All sorts of compressional #tectonic features today: thrusts, shear zones with kinematic indicators and c-s fabrics, two generations of folds and cleavage along with some later normal faults and dykes. Prof Gawen Jenkin @gawenjenkin.bsky.social Geology at Leicester

Final full day of geology at Rhoscolyn with North Wales looking at its finest! A beautiful example of how crustal thickening occurs in fold and thrust belts. The local wildlife came to see what all the fuss was about too! Geology at Leicester Prof Gawen Jenkin @gawenjenkin.bsky.social

Sampling the Foyers granite with its various facies, enclaves and magmatic fractures! Marc Reichow Sam Bright

From granulite facies metamorphism to Britain's oldest undeformed sediments and a #meteorite impact deposit that is actively being researched by those at the Leicester, today's tour of Assynt offered a bit of everything. Geology at Leicester Stewart Fishwick

Another #Assynt visit over. Today was spent looking at both the opening and closure of the Iapetus ocean and all in the same view! What a place! Geology at Leicester Stewart Fishwick

Unravelling the polyphase deformation in the Moine at Ardalanish, #Mull Stewart Fishwick Geology at Leicester

Rapid upheaval following the Cretaceous... Brilliantly white chalk hills and black lavas filling the valleys must have been quite a sight. All finished with a #caldera eruption recorded by a world class ring dyke. Topped off with a night of haggis! Geology at Leicester Stewart Fishwick

Day 1, Tenerife, 2024. An odd one without Mike leading, but a classic introduction to volcaniclastic rocks. Distinguishing eruption units, plinian fall and flow deposits and unravelling the unique features of each Cañadas eruption. Geology at Leicester #Tenerife #volcano

Some sunset geology in the mountains of Teno. Started the day in the youngest major eruption unit on Tenerife and finished on some of its oldest lavas on the shield volcano of Teno. #Masca #Tenerife Geology at Leicester

Day three and time to check out where all the action that produced the Bandas del Sur eruption units was taking place: the Las Cañadas caldera. Including cone sheets, ring dykes, pahoehoe, obsidian lavas and a major sector collapse. Geology at Leicester

Some different perspectives of Arran to those traditionally seen on undergraduate fieldtrips. The northern granite combined with some glaciation has resulted in some impressively formidable hills for such a small island, especially in winter. #Arran #granite.

Lovely spring day to get some practice in for Anglesey! Caledonian deformation in the Beacon Hill Fm offers great training in identifying and measuring bedding, cleavage, bedding-cleavage intersections and folds. All set for Anglesey now!@DrDaveHolwell Prof Gawen Jenkin @gawenjenkin.bsky.social Geology at Leicester

Day one of the 2025 Anglesey trip... What a welcome back! The type locality for the #SouthStack Formation in glorious sunshine! Plenty of folding to get familiar with here! Geology at Leicester Prof David Holwell

One of the best Anglesey days... A transect through a classic fold and thrust belt. Thrust faults, C-S fabrics, kinematic shear indicators, folds and mapping. #geology Geology at Leicester Prof David Holwell.

Congratulations to Arran Geopark on being awarded 🗻 UNESCO Global Geopark 🏔️ status! It’s fab to see Arran being recognised for its unique geological heritage, rich biodiversity, and commitment to protecting their natural heritage.
