The rock was most likely a granite...judging by the mineral contents of the rock and the coarseness of the grain. There are some relict textures present in that rock, but it's pretty much been busted up and re-crystalised for the most part. A bulk composition analysis would tell you what the source rocks were. A basaltic cataclasite looks different to this because it's bulk composition doesn't match granite...it would be a gabbro or dolerite instead.
