Can you tell us where you found the rocks, I see several things but am unsure looking at pics as the high resolution bump up is distorted to much to see the structure.

It all appears to be very mineralized quartz, the first two pictures look to be limonite *black* in quartz, pic 3 has some nice color to it.

Perhaps Manganese as well.
