sTamprockcoin Posted June 7, 2019 Share Posted June 7, 2019 Brought home and broke up a small boulder from an area the town used as a rock dump. This is either Marcellus or Harrel/Brallier Shale. Very sparkly. I know that they'll rot eventually but I'll enjoy them in the meantime! I think that the 4th photo shows a trilo bit or maybe another brach. 1 Link to post Share on other sites
Mark Kmiecik Posted June 8, 2019 Share Posted June 8, 2019 Nice finds. Search pyrite disease or pyrite rot both on this forum and online. Lots of info and various methods. I believe most have failed, but you may find something useful. Link to post Share on other sites
sTamprockcoin Posted June 8, 2019 Author Share Posted June 8, 2019 Thanks Mark, I've read the info & debates. To be honest none of this stuff is worth much if any effort. If the tubular thing turns out to be pyritized poop as Rockwood suggested (in the ID forum) I'll coat it with clear nail polish and see what happens. Most of the time my attitude is what I expressed in my post - enjoy it while I can then move on. Link to post Share on other sites
Plax Posted June 18, 2019 Share Posted June 18, 2019 My experience with paleozoic pyrite older than carboniferous from PA is that it doesn't rot so much as just discolor. On the other hand Cretaceous pyrite or marcasite form Delaware, NJ, NC etc rots in just a couple of decades. Link to post Share on other sites
