MOROPUS Posted May 28, 2008 Share Posted May 28, 2008 i found this last weekend looking for arrowheads in ohio,its heavy,about 2 lbs,a magnet wont stick to it ,but a metal detector goes off on it,anybody know what it could be try to heat it with a lamp;if then attract a magnet, it is pirrotine(spell like that?),with the formula:Fe11S12.If not, no idea.It cold be a tipe of rock,with many minerals (including iron): Skarn... There are very good mineral pages in internet.Try to look there.Hope it helps you! Link to comment Share on other sites More sharing options...
Guest solius symbiosus Posted May 28, 2008 Share Posted May 28, 2008 It is virtually impossible to ID a mineral from a photo. Whatever it is, it looks like a piece of road metal from a RR track, or something that was deposited by glaciers. THIS site has some good links for IDing.
