mr fossil Posted October 5, 2022 Share Posted October 5, 2022 Hello, I found this rock in a metamorphesized area of chlorite schist with tons of giant quartz veins everywhere. I found this mineral which I have never seen before and it was also present in the quartz. it’s brown and coarse as if it were sandstone. What could it be?

FranzBernhard Posted October 5, 2022 Share Posted October 5, 2022 Could be calcite or dolomite. Put a small fragment in vinegar or HCl - what happens? Franz Bernhard Link to comment Share on other sites More sharing options...
ynot Posted October 5, 2022 Share Posted October 5, 2022 I think it looks like oxidized iron. Maybe staining a granular quartz vein. Darwin said: " Man sprang from monkeys."
