John Strachey (born May 10, 1671, Chew Magna, Eng.—died June 11, 1743, Greenwich) was an early geologist who was the first to suggest the theory of stratified rock formations. He wrote Observations on the Different Strata of Earths and Minerals (1727) and stated that there was a relation between surface features and the rock structure, an idea that was not commonly accepted until a century later.
