Can anyone identify these black and metallic rocks ? Black kidney hematite photo -red streak. Black stand alone rock - black streak. Black and crysta rock - the black substance - black streak. Silver mica looking metallic rocks - black streak. Splattered black paint look rock - no idea what it is. Nothing appears magnetic. General area - White quartz reef outcropping, lots of white quartz, brown/green slate, a lot of assorted black rocks. Also found reasonable amount of what looks like smoky quartz. (No real rusty quartz or gold at first view). Just looks volcanic/iron rich different to another quartz reef I have seen. Pinpointer over rocks collected - set off no noise. Appreciate any feedback.
