Re: Cacite from unknown locality

[quote=”Pete Richards”]This specimen has a strong affinity with travertine, which is a rock composed of layered deposits of calcite, such as might be found in cave formations, but differs in having obvious tooth-like structures oriented perpendicular to the travertine layers. I suspect that these may be due to selective dissolution of an originally solid travertine, but how this happened I will not hazard to guess. Unless some list members with detailed knowledge of the Ilfeld (or some other) locality have specific knowledge of other specimens like this, I would say there is minimal possibility of determining a locality for this specimen.[/quote Dr. Richards, Thank you for your reply. The more I look at this specimen the more it looks like a cave formation that could come from many different places. Perhaps I took this picture with the specimen “upside down.”. 🙂 Again thank you.
