[QUOTE="shivan, post: 158622, member: 194"] I think mfdes has got it. When i first started my Geo course, i spent a few trips out to a local hard rock mining area to try and put my knowledge to work. I found an outcrop very similar to your pictures and thought it was Bornite (peacock ore) because of the rainbow staining. I was then told by my lecturer it was from the oxidation of sulphides. Bornite is more of a iridescent blue and purple as oppose to the rainbow stain. This is what i had found: [url=http://s1198.photobucket.com/user/shivanemissary/media/Rocks/DSCN3402_zps8fbc6d4b.jpg.html][img]http://i1198.photobucket.com/albums/aa454/shivanemissary/Rocks/DSCN3402_zps8fbc6d4b.jpg[/img][/url] [url=http://s1198.photobucket.com/user/shivanemissary/media/Rocks/DSCN3406_zpse9076c81.jpg.html][img]http://i1198.photobucket.com/albums/aa454/shivanemissary/Rocks/DSCN3406_zpse9076c81.jpg[/img][/url] [/QUOTE]
