Are sulfide rocks?

sorry for quality

I resized them for you. It's a little better, yes?

gergovia:

Nice photos of some heavily mineral rocks, but I don't completely understand your statement or was it posted as a question.

Are you asking if "these" rocks are a sulphide? If so, then the answer is,,, maybe at some time in the past they might have been a sulfide mineral, but because they have been exposed to the weather for a long period of time and have now converted to an (iron) oxide. Take a hammer and break one open and examine a fresh surface. If they contained a sulfide mineral it will show on an unexposed surface.

Good luck,

John
