ynot Posted March 13, 2021 Share Posted March 13, 2021 Where was it found? Looks more like limestone than chert. Could be caliche, quick lime or oxidized surface on chert. 1 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

LabRatKing Posted March 13, 2021 Share Posted March 13, 2021 Looks like calcite on quartzite. We see a lot of this in Millard county Utah and other fossil sites. Under a black light, you may find these glow orange. Link to comment Share on other sites More sharing options...
daves64 Posted March 13, 2021 Share Posted March 13, 2021 I'm curious about what is in the area circled in red. Accomplishing the impossible means only that the boss will add it to your regular duties. Link to comment Share on other sites More sharing options...

I agree; this is not chert. It's likely limestone with "cherty" inclusions and calcareous encrustations. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
