The most incredible geological outcrop I've ever seen. A diapir of Triassic red mud (left) thrust up through younger Cretaceous limestone (right), partially melting and recrystallising it. #geology

Chunky gypsum crystals near Alicante, Spain. A fascinating area where Triassic sands have been thrust up through younger Cretaceous limestone and overlain by Miocene lacustrine muds. All run through with gypsum veins and evaporites. #geology

Wish I had more time to sit down and sketch the folding and faulting here, bit of a mess! #geology

These stromatolites were formed in a circle around a depression, possible rock pool?

Orkney surprised me with some lovely geology - stromatolites, folds, faults and stacks #geology #orkney

Lots of fun little critters. Foraminifera, algae and bryozoa found in a reef from the early Eocene (~50 million years ago). #thinsectionthursday

The wonderful tiny worlds of minerals and fossils down a microscope. Identifying them is the hardest part of being a #geology student.
