Rock in a surprising place

Yesterday we demonstrated the ioLight field microscope at The University of Oxford’s Earth Sciences department. Owen Green (also fellow of the Royal Microscopical Society@RoyalMicroSoc ) had some fantastic rock samples to test the ioLight pocket microscope with, including this rather exciting one.

We took the above image with the ioLight pocket microscope. The image is 1mm wide showing a polished section of rock. (ioLight pocket microscope)

If you are a geology expert, you will recognise this as a rather nice section through a sedimentary rock – ie one that was formed from debris that has accumulated at the bottom of the sea. This doesn’t sound that exciting until you find out where the rock sample came from – the summit of Mount Everest!  – proof that the tip of the highest mountain on earth was once at the bottom of the sea.
