Minette Lamprophyre dyke on Sale Fell

 



We found this dyke close to the summit of Sale Fell on the Cockermouth side. The rock is a type of Lamprophyre called a Minette. I'm just getting to grips with this type of rock so seeing a known example was helpful. It seems to have large pink crystals. The dark patches look like lichen where some crystals have eroded out.
