Glassballhoarder Posted March 6, 2013 Share Posted March 6, 2013 I came upon these two things and I can't figure out what they might be. I found them in the White river formation in SD. Is it corrall? it almost has a mettalic ring when tapped, and seems alot denser than most things I pick up. Thanks for all the help! Link to comment Share on other sites More sharing options...
Herb Posted March 7, 2013 Share Posted March 7, 2013 I have seen cherty limestone that looks similar and had a sort of ring to it.

MammothPaleoGuy Posted March 7, 2013 Share Posted March 7, 2013 There are big fat veins of silica running filling in cracks all through the White River. Seriously hard stuff. Link to comment Share on other sites More sharing options...
Glassballhoarder Posted March 11, 2013 Author Share Posted March 11, 2013 Thanks for all the help! when I first found it, I had thought it was a piece of ore of some kind, judging by the density and the ring when tapped. Link to comment Share on other sites More sharing options...
