Soot, though, is made of Carbon, C, and this mineral, while sooty or soot-like in texture and color, is a copper mineral with Cu in it.<BR/><BR/>Any copper geologist would get this supergene mineral right away. There are only two minerals that this could be as far as I know, but one is more common or more commonly cited, anyway.Silver Foxhttps://www.blogger.com/profile/03131032620978696727noreply@blogger.comtag:blogger.com,1999:blog-8693614218792476252.post-68398964513290990792009-03-18T12:03:00.000-07:002009-03-18T12:03:00.000-07:00"Now, what is the sooty black copper mineral?
