There's a lot going on in this block. First, there's the exquisite weirdness of blueschist, which never really gets old, no matter how much time you spend at Bandon's jetty. Next, it looks as if the rock was cataclastically shattered during metamorphism; the white slabs (quartz?) on the left can be sensibly reassembled into a more or less coherent whole. On the other hand, the clasts around and above the hammer's head look more chaotic. Finally, there are a number of what appear to be veins shooting through in a few places. The two that are clearest are running through the slabs on the left.
