All the Stratigraphies
Preamble: This post outlines the development of formal stratigraphy, focusing on Chronostratigraphy. Entire books have been devoted to this topic; one of the most entertaining and enlightening is Martin Rudwick’s excellent account of the conduct of 19th century gentlemen who argued the case for the Devonian. My account is woefully brief, but there you have […]
