New Members Larie213 Posted April 22, 2022 New Members Share Posted April 22, 2022 Identification help, the microscope picture is pretty bad but it is a handheld and my cell phone, hopefully this helps though. I rinsed this stone in a 70% muriatic acid and water solution, initially it was smooth but once rinsed with the acid water solution it became very rough like sandpaper. The crystals that have been exposed on the surface jut outwardly, perpendicular from the surface, some are tetragonal or trclinic and some are orthorhombic or monoclinic in shape, it is hard to tell with my microscope.

Rockwood Posted April 22, 2022 Share Posted April 22, 2022 Might be a good idea to keep looking for micro fossils like conodonts. I doubt it is a fossil as a unit though. Link to comment Share on other sites More sharing options...
