... observations on cherts ...

für deutsche version hier clicken!

This column is dedicated to observations on cherts, particularly on those with fossils. It is meant to show the broad diversity of types, the richness of detail in their fossil content, or the sheer beauty of their cut and polished faces. Devoting some of one's spare time to cherts can be emotionally rewarding since there are a lot of enigmatic features awaiting explanation, and there are fair chances for anyone to find out something remarkable or even unique.

The contributions could be readily understandable concise versions of published or unpublished papers, ideas concerning observations, or plain reports on finds which might be of interest. Professionals as well as non-professionals are invited to contribute. Please contact me.
