Fossildude19 Posted January 10 Share Posted January 10 Chert, for the first 4, ... then an agate, and finally a piece of limestone. Maybe a fossil in the limestone. 3 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

daves64 Posted January 10 Share Posted January 10 I'm not sure the 5th one is agate or chert. The chipped areas are all wrong for either type, not conchoidal. The raised chipped areas look too rough, like from a softer stone, or maybe slag. But I do agree on 1-4 being chert. 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...
