Title: Couple of unknowns Im trying to ID.
Post by: Gergis on November 30, 2015, 10:58:04 AM

Got a few new unmarked mineral specimens this past weekend and need some help with identification on these two definitely. I think this first one is a possible riebekite but uncertain. The second piece is a pyrite psuedomorph of some sort I believe. Any help is appreciated :-)  (http://images.tapatalk-cdn.com/15/11/30/c60e5b437fa1a71e31f1ac8f97e37e95.jpg) (http://images.tapatalk-cdn.com/15/11/30/38c78e2d945a53acb0002925f82313eb.jpg) (http://images.tapatalk-cdn.com/15/11/30/d3b215f126453f628dfa11337734d304.jpg) (http://images.tapatalk-cdn.com/15/11/30/0e0d07ca40a4c3506d503720bebef93f.jpg)

The first thing that popped in my head was bismuth for the first.  Hard to say on the second. If you come up bring them as I have lots of mineral books.
