Geotourism experts with scenery, volcanoes and fossil holidays around the world and the UK, and polar expedition cruises.

<p>Another great day in the #jurassiccoastworldheritagesite Our first stop was the @etches.collection in #kimmeridge where we were lucky enough to have a guided tour by Steve Etches who found the fossils in the museum. Pic 1 shows one the most amazing finds: the world’s first known #ammonite eggs. Great to see on Easter Day! Pic 2 shows an #icthyosaur with a deep chest cavity suggesting it was a deep diver. Pic 3 shows a #plesiosaur bone with a cut from a #pliosaur tooth. Pic 4 is a model of a pliosaur eating an icthyosaur Pics 5 and 6 are of fossils on Kimmeridge beach where no fossil collecting by the public is allowed. Incidentally Kimmeridge lends it’s name to the #kimmeridgian stage of the #jurassic and is the source rock of North Sea Oil. Pic 7 is of #chesilbeach a barrierbeach formed by longshore drift. Pic 8 is of the ammonite graveyard on #monmouthbeach #lymeregis  Pic 9 is James Cresswell with a giant ammonite on Monmouth Beach and Pic 10 is also a large ammonite. We are staying the next 2 nights here in Lyme Regis. @jurassiccoastofficial #geology #geotourism #palaeontology (at The Etches Collection)<br/>

<p>Great first day of our #england trip. We left London Heathrow Airport this morning and drove to the #stonehenge #worldheritagesite Here we learnt how the henge was built in 3 phases from 3100 BC to 2000 BC. The larger stones the Sarcens are derived from 25 miles away while the smaller Bluestones, which are dolerite, derive from 150 miles away in the Preseli Mountains while the altar stone has come from the #breconbeacons. Next we drove south to reach the #jurassiccoastworldheritagesite Our first step was #oldharryrocks a sea stack made from Cretaceous chalk. We then visited a #brachiosaur #dinosaur trackway in Purbeck limestone of the latest #jurassic This was followed by a welcome drink in the #squareandcompass pub which hosts it’s own geology museum. We are spending the night in the charming village of #corfecastle  (at Stonehenge)<br/>

<p>This week we did 2 day tours in the #fforrestfawr #geopark in the #breconbeacons #nationalpark #wales Pic 1 shows the summit of #penyfan the highest summit in southern Britain. The top layers are upper #devonian sitting uncomformably on lower Devonian layers. Pic 2 taken on the summit of Pen-y-Fan shows ripples in the Upper Devonian Plateau Beds which are fluvial in origin. Pic 3 shows the neighbouring summit of #cribyn Pic 4 is me at the summit. Pic 5 is a 5,600 year old #yewtree which is possibly the oldest in Europe. Pic 6 is #bwamaen (The Stone Bow) which is a Variscan aged fold in #carboniferous #limestone Pic 7 is of #sgwdyreira (The #waterfall of snow). It is possible to walk behind this fall. Pic 9 is of #henrhyd the highest #waterfall in the Geopark which flows over the #farewellrock the boundary of the coal measures. At this site a fossil tree trunk was discovered, and the waterfall was filmed as the entrance to the bat cave in a Batman movie. Pic 10 also taken this week is additionally included.  It is #minchinhole #cave not in the Geopark but on #gower. I took a personal trip there with my son. This cave is the discovery site of Straight Tusked Elephant, rhino, mammoth, wolly rhino and hyena fossils. (at Fforest Fawr Unesco Global Geopark)<br/>

<p>Our #namibia #geology tour is virtually at an end. We depart to tomorrow after visiting the Geology Museum in Windhoek. Here are some pictures of the last 4 days which in addition to geology included 2 days of game viewing in #etosha #nationalpark Pic1 shows James Cresswell and the Hoba #meteorite which fell to the earth 80,000 years ago and is the largest meteorite ever found. Pic2  the Tsumeb mining museum which is just up the street from the now abandoned #tsumeb mine. The mine was one of the world’s best mineral mines and in it were found the world’s best crystals of Azerite and Dioptase. Pic3 shows the #waterberg escarpment. The rock is #jurassic sandstone. The escarpment is caused by the reactivation of a Precambrian fault (Damaran) when Gondwana split to form the South Atlantic. Pic 4 shows cap carbonates that signify the end of #snowballearth   Pic5 is an African #elephant. Pic6 shows a mother and calf Black #rhino Pic7 shows a Spotted #hyena Pic8 shows Zebra Pic9 shows sleeping lions and Pic10 is of an Angolan #giraffe  (at Hoba Meteorite site - Grootfontein Namibia)<br/>

<p>Today was an absolutely superb #geology day on our #namibia trip. We saw a #petrifiedforest , #snowballearth dropstones, the #twyfelfontein #worldheritagesite rock engravings, foliated granite and the oldest rock of our trip. Pics 1-4 show 270ma #permian petrified trees which grew in cold humid conditions and were up to 30m high. The trees are contained within fluvial sediments of the Karoo supergroup. Pics 5&6 show dropstones: pebbles that were dropped out of iceshelves or icebergs in Snowball Earth 630ma a time when the whole planet was glaciated. These pebbles were then stretched and deformed as the Damara mountains uplifted. Pic 7  shows a syntectonic granite with large feldspar crystals orientated to the stress field. The granite is around 600ma. Pics 8 and 9 are from the Twyfelfontein WHS and are between 4 and 8 thousand years old. Pic 8 is the most famous is the ‘Man-lion’ Pic 9 shows a giraffe but also a furseal and penguin showing the people travelled to the coast 200km away. Pic 10 was the oldest rock of the trip, a 2.2 billion year old paragneiss of the Congo craton. (at Namibia)<br/>

<p>Today was spent in the vicinity of Brandberg, Namibia’s highest mountain a granite intrusion emplaced by the Tristan da Cunha hotspot around 130ma. Pic 1 shows the ‘White Lady’ a 2000 year old rock painting that is actually a man, a shaman. Pic 2 shows a dolerite dyke coated in desert varnish at the base of the Brandberg. Pic 3 shows a tree damaged by Nambia’s famous Desert Elephants. Pic 4  shows more rock art. Pics 5 and 6 tell a fascinating story. They are polished granites on with a palaeo surface that is the base of the Karoo (700ma granites but 300ma surface) The surface appears to have glacial striations from the ice age that covered Gondwanaat this time! Pic 7 shows a type of rock called Pyrophyllite it is a metamorphic rock (a hornfel) that was once a lacustrine Karoo sediment. It was brecciated (broken up) by the Brandberg granite busting through and was contacted metamorphosed. It forms a beautiful rock that was once mined as ornamental stone. Pic 8 shows a pit where a pegamatite vein was mined out for it’s gem quality green tourmaline crystals. Abundant black tourmaline and mica sheets can still be found here. Pic 9 shows the national emblem plant of Namibia: Welwitschia. This amazing desert plants can capture moisture from coastal for and can live to over 2000 years old. Pic 10 shows Karoo sediments stacked against the Brandberg granite that previously pushed through them.<br/>

<p>Today we left the Erongo volcano complex and headed via some dolerite dykes to #spitzkoppe the most beautiful mountain in #namibia After this we visited the #uis #tin #mine at the foot of #brandenburg Namibia’s highest mountain. Pic shows Spitzkoppe. The mountain is a granite intrusion that was emplaced around 120 million years ago by the Tristan da Cunha hotspot as the Gondwanaland was beginning to split. Pic 2 is the view under an arch of Spitzkoppe granite. Pic 3 shows boulders of the granite. Pic 4 shows a dolerite dyke with a chilled margin. It and many other dykes were emplaced as Gondwanaland began to split and the South Atlantic begin to form. Pic 5 shows a larger dolerite dyke. Pic 6 shows the eroded remains of the #erongo #volcano  a 35km diameter volcano that had a 7 caldera forming eruptions 128 million years ago. Pic 7 shows the Uis tin mine and a white #pegmatite vein can be made out. These veins contain the tin ore kassiderite and rare earth elements. The mine is built over a swarm of 120 pegamatites. Pic 8 shows Nicole describing a piece of Pegmatite at Uis mine. Pic 9 is also Uis Mine and Pic 10 is the group having a sundowner drink on a feldspar spoil heap above the mine. (at Namibia)<br/>

<p>Today was the 7th day of our #namibia #geology tour. We started in the town of Swakopmund which is cooled by the Benguela current. Here pics 1&2 We visited the Kristall Gallerie. Pic 1 shows James with the world’s biggest quartz crystals that are on display. Pic 2 shows the crystal garden which had many minerals e.g. tourmaline, amethyst, and flourite  inside the pegmatite dykes they were mined from. We then return to the desert our first stop was a road side mineral market where incredible specimens were for sale (Pic 4). We then moved the the Jurassic volcano of #erongo that was formed by the Tristan da  Cunha hotspot and has been intruded by granite. In the granite we learnt about arid weathering and saw 2,500 year old rock art  Pic 4 shows some of this granite. Pic 5 shows a nest of tourmaline crystals within the granite. Pic 6 shows how the tourmaline nests are more resistant to weathering than the surrounding granite. Pic 7 shows the rock art. Pic 8 shows where ochre was prepared for the painting. Pic 9 shows a granite stack that has been formed purely from wind erosion and sand blasting. Pic 10 shows our luxury tent accommodation.<br/>

<p>Days 5 and 6 of our #namibia #geology tour: Picture 1 shows our German/Namibian guide Nicole Grunert explaining boudains in #amphibolite. This amphibolite formed when the Congo and Kalahari cratons separated during the splitting of the Rodinia super continent 900 million years ago. In the basin inbetween the cratons, sediments were deposited which were intruded by basalt dykes. 620 million years ago the 2 cratons re-collided crumpling the sediments up into fold mountains and changing the dykes to amphibolite. The boudins ‘sausage structures’ have formed as the amphibolite was extended during the crumpling. Pics 2 and 3 are of 20 million year old dunes that lie directly beneath the modern dunes of the Namib desert showing it’s the oldest desert in the world. Pic 3 has a burrow or plant root structure going through the dune sandstone. Pic 4 shows our group crossing the Tropic of Capricorn. Pic 5 shows detail of the boudins also shown in picture 1. Pic 6 might look ordinary but has an incredible story to tell. It is a graphite schist and is part of a metamorphosed #ophiolite sequence called the “Matchless Belt”. Ophiolite is oceanic crust that has been thrust onto the continent and this occurred here when the Damara sediments were crumpled up. The organic material of the graphite is thought to derive from organisms that lived around hydrothermal vents on the ocean floor!  Pic 7 shows a Quiver Tree the branches of which are hollow and have been used to carry arrows. Picture 8 shows the coast at Walvis Bay. Here the temperature was 20 https://www.instagram.com/p/BvJuG7agKKp/?utm_source=ig_tumblr_share&igshid=1oqwv5r0ozcjc

Here the temperature was 20'C cooler than inland due to the cold Benguela current from Antarctica. This cold current is responsible for Namibia’s aridity. Pics 9 and 10 show a boat tour we tour on Walvis Bay Lagoon in search of wildlife, it was so cool we had to wrap up warm - a marked contrast to the 40'C temperatures of the interior!

<p>Today was the final day of our #oman #geology tour. The first picture of the post was our last stop - a large scale fold inside a larger sheath fold. The first stop of the day was to inspect an unusual lava called #carbonatite which contained veins of #amerthyst We then stopped at a notch cut into rock by molluscs when the sea level was higher in the last interglacial. Then we visited a Miocene #wavecutplatform which was overlain by Quaternary corals. We then took a boat across a river and headed into #wadishab which is considered by many to be Oman’s most beautiful Wadi. After a picnic lunch at the Wadi we visited a fascinating site with a #tsunami deposit. This was followed by the #bimmahsinkhole which is actually a #doline. And our final stop was the the world’s largest sheath fold that contained many smaller  isoclinal #folds (at Muscat, Oman)<br/>

<p>Today was the penultimate day of our #oman #geology tour. Our first stop (picture 5) was to see rocks of the precambrian crystalline basement (800 - 1000 million years old). At this site granites were intruded by basalts which were themselves cut by #pegmatite veins. Our next stop (pictures 6 & 7) was to see a rare volcanic rock called #kimberlite that brings rock up from very deep in the mantle and sometimes contains diamonds (although not in this case). We then visited the #motherofalloutcrops seen in pictures 1-4.  Here red radiolarian chert is interbanded with white porcellanite. These sediments were deposited in water 4000-4500 meters deep. They are folded and faulted and were trusted onto Arabia as the Batain Nappe 15-20ma after the emplacement of the Semail Ophiolite. We then had our picnic lunch before heading to a Manganese Pit which is located in the same sediments. Our final stop was Ras al Hadd where there is a Bronze Age settlement and a turtle nesting beach. Here we are spending the night. (at Oman)<br/>

<p>Another day in #oman We started by visiting the #bahla fort #worldheritage Site which sits on ophiolitic rocks. We then took a train ride into Al Hoota cave (photography was not allowed inside the cave). We then visited<br/>
Falaj Daris Nizwa World Heritage site to see the ancient irrigation system. After a traditional Onani lunch in Nizwa we drove to a site where plagiogranite could be seen. This forms by partially melting of gabbro within the ophiolite. We then had a distal view of the #moho on a mountain side with the bulk of the mountain made of peridotite and the top of the mountain capped by gabbro (the cover photo of the post). Finally we reached the #wahiba sands where we drove into the dunes for a desert experience.<br/>

Today we were joined by 2 geologists from the ‘German University of Technology’ in Muscat, including Gosta Hoffmann who wrote the excellent book: a 'Field Guide to the Geology of Northeastern Oman’. Our first stop was the Al Ayn beehive tombs #worldheritage Site. Here we not only observed the early #bronzeage #tombs we also observed the Hawasina sediments on which they stood. Our next stop was viewpoint of Jebel Misht - an 'Oman exotic’. The whole mountain represents and submarine volcano with atol on top which was scrapped on to the continent as part of the Hawasina nappe! We then viewed a large chevron fold in the Hawasina sediments, before climbing to one of the highest points in Oman to view the 'Grand Canyon of Arabia’. Here the entire #cretaceous and #jurassic autochotonous sequences could be seen. After a picnic lunch we observed some rudist fossils before visiting the abandoned old town of Al Hamra. Our final stop of the day was another archaeological one at 'Coleman’s Rock’ to observe important ancient rock engravings. (at Oman Grand Canyon Jabel shames)

<p>Today we focused on the oceanic  #sediments of the Hawasina group that were also thrust onto Arabia with the Semail #ophiolite In the morning (photos 10 and 9) we visited a fossil white smoker distinguished from the black smoker from yesterday by the large amount of opal found at the site. We then moved on to the site of a 1000 year old copper mine that had pillow basalts, dikes and columnar cooling joints to be seen. We then crossed off the Semail Ophiolite nappe and on the the Hawasina nappe. Where the hot Semail nappe thrusted over the Hawasina nappe an ‘ironing’ effect occurred, metamorphoseing the rocks along the thrust fault. This is called the #metamorphic sole. We stopped to examine rocks in the metamorphic sole (photo 8). We then moved into the spectacularly folded Hawasina sediments. These sediments were lain down in deep water conditions but were still partially made of turbidite flows. The highlight of the sediments were the amazing mullions observed in photo 1. #geology #geotourism #oman #structuralgeology  (at Oman)<br/>

<p>Another great day in #oman Today was all about seeing rocks of the mid ocean spreading ridge that have now been obducted on the surface as part if the Semail #ophiolite We visited the #geotimes Wadi al Jizzi #pillowbasalts - the best pillow basalt outcrop in the world! We visited a fossil black smoker examining it’s copper #mineralization We saw metal rich umber sediments. We saw the sheeted dike complex, hexagonal cooling structures and lava feeder tubes. We ended by visiting a copper mine that had been mined for most of the last 4000 years and saw what may be the only ziggurat in Arabia, built by early copper miners from Mesopotamia. (at Wadi Al Jizi Power Company)<br/>

<p>A fantastic first day on our #oman #geology tour which we are running with the help of @goldenhighlands Our first stop was Wadi al Abyad the best place in the world to see the #moho - the boundary between the earth’s crust and #mantle We then moved to Wadi Haslan where we had a sumptious picnic lunch and examined #snowballearth deposits: 712ma #tillites and glacial lake deposits with dropstones immediatly overlain by tropical dolomites. We then moved on to a site of an #unconformity between #precambrian rocks and #permian rocks. The precambrian rocks contained #stromatolites while the Permian rocks showed a marine transgression from a beach to limestone. A great first day in wonderful Oman! (at Oman)<br/>

<p>Today was our last day on #lapalma we travelled up to the highest point of the island: Roque de los Muchachos here we saw a large number of #telescopes from many nations around the world and were able to look down into the #taburiente #caldera Then after lunch drove to the other #volcano #cumbrevieja and hiked to Llano del Banco #vent In 1949 lavas flowed from this vent down the west side of the island producing the lava delta we had seen the day before. #canaryislands #spain #geology #geotourism #volcanoes  (at Roque de los Muchachos Observatory)<br/>

<p>Just completed our 2nd day on La Palma part of our #canaryislands : #volcanic island hopping tour. Today we focused on the #cumbrevieja #volcano that forms the southern half of the island. We inspected several #lava flows, saw lava deltas and levees and also visited the San Antonio cone this is a prehistoric #phreatomagmatic cone that also erupted in 1677. From the summit of the cone there were superb views of the Canary’s most recent eruption: #teneguia that erupted in 1971. (at Volcan san Antonio)<br/>

<p>We had a great walking day today in #lapalma ’s #taburiente #caldera <br/>
 #nationalpark Our first stop was #cumbrecita viewpoint where we took a short hike and learnt how this ‘caldera’ (the first place in the world to be called a caldera) formed. It was by https://www.instagram.com/p/BrYO0WbgIJk/?utm_source=ig_tumblr_share&igshid=5knbhig2sdr3

We had a great walking day today in #lapalma ’s #taburiente #caldera
#nationalpark Our first stop was #cumbrecita viewpoint where we took a short hike and learnt how this ‘caldera’ (the first place in the world to be called a caldera) formed. It was by 'sector collapse’ of the Taburiente #volcano (a giant landslide with a large part of the island slipping into the sea) and the subsequent emergence of the #bejenado #volcano followed by erosion. We then visited the National Park Visitor Centre followed by a hike into the base of the caldera where some incredible #geology was seen. The rocks here show the story of an emerging #seamount with slightly metamorphosed deep water #pillowbasalts, then shallow water pillow basalts, followed by volcanic breccias formed as the island was emerging. The whole suite of rocks was then intruded by many #dykes as the island continued to grow above. It was an amazing and beautiful hike. (at Caldera de Taburiente)

<p>Wonderful day on La Gomera today. We did a complete loop of the island seeing the inner eroded plumbing of a Miocene and Pliocene volcano. We saw many #phonolite and #trachyte intrusions + #dykes as well visiting #garonjonay national park and #worldheritagesite In the park we walked and checked out the unique botany. Finally we boarded a ferry to La Palma which will be our base for the next 4 nights. #lagomera #canaryislands #geology #geotourism  (at La Gomera, Islas Canarias)<br/>

<p>We’ve just finished our 2nd day of our #canaryislands #volcano tour. We went to Garachicoand saw how lava destroyed the port in the 1600’s we then moved on to Punta de Teno and examined an eroded scoria cone. We then travelled through the eroded Miocene #teno volcano on a single track and very winding road. We were rewarded with breath taking views and saw many dykes. After lunch we headed to #chinyero crater to see #tenerife ’s most recent eruption (1909). After this we had coffee in Adeje and viewed the oldest rocks in Tenerife. Next we checked out the Adeje #ignimbrite deposits formed by #pyroclastic flows after Plinian eruptions. Our final stop was #calderadelrey an unusual felsic and highly explosive phreatomagmatic crater. We then boarded a ferry to La Gomera island where we are spending the night. (at Tenerife)<br/>

<p>We had a great first day on our #canaryislands #volcano trip. Our first stop was Amarilla phreatomagmatic cone to see palagonite tuff, before we headed up to the #teide  #nationalpark and #worldheritagesite In the park we saw accretionary phonolite lava balls, cone sheet dykes, the 1798 Chahorra eruption of #picoviejo #losazulejos  and the #roquesdegarcía before the highlight of the day - the summit of #spain ’s highest #mountain : Teide. We took the cable car up to 3550 meters above sea level, then walked (using a permit we had to obtain 3 months in advance) to the summit at 3718 m. At the top we looked into the summit crater which contained #fumeroles and #sulfer and had incredible views! After our descent we saw #obsidian and #pumice visited a visitor centre and had coffee. We are spending the night in La Laguna World Heritage Site. (at Teide)<br/>

<p>Our #morocco trips has come to end end. Yesterday we left the Sahara and visited one more Devonian #trilobite site in the Anti-Atlas before stopping for lunch at the amazing #todragorge The gorge in the High Atlas has formed as a river cut down through well jointed #jurassic #limestone as the High Atlas have simultaneously been uplifted as Africa collides with Europe. We then spent the night in Ouarzazate, continuing today to Marrakesh via the #kasbah #aitbenhaddou #worldheritage site. This amazing fortified settlement was built in the 11th centuary and is on the trading route from Marrakesh to Timbuktu. We will be repeating this trip in November 2019 and already have 5 people signed up: <a href="http://www.geoworldtravel.com/morocco.php">http://www.geoworldtravel.com/morocco.php</a><br/>

<p>Another great day in #morocco after leaving our hotel which is situated in the Erg Chebbi #sanddunes in the #sahara we visited the #devonian carbonate mounds known as the Kes Kes. Here we observed #coral and #trilobite fossils. We then visited Erfoud quarry seeing where Orthoceras slabs are quarried. We then had a picnic lunch at a mid Devonian site with many more fossils to see. Next we visited bell pits that were being dug by miners who mine #crinoids this site was in the lowest Devonian, from here we walked to another Orthoceras site that was in #silurian sediments. Next we went to an Orthoceras factory where the giant quarried slabs we saw earlier are fashioned into table tops, basins, shower trays, plates and almost anything else you can imagine. The day ended with a visit to Erfoud Museum where many magnificent fossils were on display. (at Merzouga - Sahara Desert)<br/>

<p>Today we visited the famous #kemkem beds which are #cretecous (Cenomanien) river channels and are the discovery sites of #dinosaurs #spinosaurus   and #carcharodontosaurus At the site we examined the river channels and saw fossils that were being mined by miners including fragments of bone, crocodile skin, dinosaur teeth and fish vertebrae. We then continued to the #filon12 mineral mine and took an underground tour. The miners showed as samples of #vanadinite #goethite #haematite and many other minerals. After this we visited a late #silurian site where #crinoids have been mined. These crinoids were actually a pelagic form that floated in the water column aided by a float or lobolith. There were many of these floats and #crinoid stems that could be examined. We then visited #merzouga lake with the hope of seeing flamingos before spending a second night here in Merzouga.
