Dunham classification: History & Overview

The Dunham classification system for carbonate sedimentary rocks was originally devised by Robert J. Dunham (1924–1994) in 1962, and subsequently modified by Embry and Klovan in 1971 to include coarse-grained limestones and sediments that had been organically bound at the time of deposition. The modified Dunham Classification has subsequently become the…
