Diggingd 2 Posted March 5 Me again with another new find, me and a buddy were out in the desert mountains when we found this, at first guess I thought it was calcite, but it does not react in vineagar, but does scratch with a fingernail. any ideas on what it could be would be super helpful. Also it grows in these super interesting formations. the last picture is a small piece I cleaned up. Quote Share this post Link to post Share on other sites
Old Tom 837 Posted March 5 Asbestos grows like that but I see some what looks like quartz in there. Hard to tell unless it is in hand. Old Tom Quote Share this post Link to post Share on other sites
Morlock 1,023 Posted March 5 I'm thinking selenite. Can you scratch it with your fingernail? 1 Quote Share this post Link to post Share on other sites
d_day 145 Posted March 5 Yeah, most likely selenite, but might also be a number of borate minerals. Quote Share this post Link to post Share on other sites

Diggingd 2 Posted March 5 Cool that's awesome, I've found some desert rose in a sand wall at the base of this mountain so I would not be surprised if it is selenite Quote Share this post Link to post Share on other sites
Diggingd 2 Posted March 5 Oh forgot to add the top white part is another rock (most likely the matrix it grew on) which is super soft almost clay like, but slightly harder. Quote Share this post Link to post Share on other sites
bigrex 52 Posted March 8 I'd also say selenite. Quote Share this post Link to post Share on other sites
