The Dunham classification system for carbonate sedimentary rocks was originally devised by Robert J. Dunham in 1962, [1] and subsequently modified by Embry and Klovan in 1971 [2] to include coarse-grained limestones and sediments that had been organically bound at the time of deposition. The modified Dunham Classification has subsequently ...Download scientific diagram | Photomicrographs of carbonate microfacies (all in plane polarized light) of early to late Viséan limestones.
