Have you done a hardness test? An acid test? It is hard to tell from just a picture. Looks like quartz or calcite, but with just a picture it is hard to tell.

Obviously a breccia- likely from a fault zone.  Likely that the white veins are quartz, but as OW said, they could be calcite. Not sure what the host rock is- the purple color could either be quartzite or altered rock.
