Crystalline limestone sedimentary rock.
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 ...
economic natural resources involve sedimentary rocks. Resources such as coal, oil, natural gas, gypsum, aggregate (sand and gravel), and salt are all found within sediments. Sedimentary Structures .

This rock formed when water was saturated with calcium carbonate that precipitated as tiny crystals of calcite. Organic Sedimentary Rocks. Organic sedimentary rocks form from the action of ...Sedimentary rock - Clastic, Chemical, Organic: Conglomerates and breccias are sedimentary rocks composed of coarse fragments of preexisting rocks held together either by cement or by a finer-grained clastic matrix. Both contain significant amounts (at least 10 percent) of coarser-than-sand-size clasts. Breccias are consolidated rubble; their clasts are angular or subangular. Conglomerates are ...Gneiss usually forms by regional metamorphism at convergent plate boundaries. It is a high-grade metamorphic rock in which mineral grains recrystallized under intense heat and pressure. This alteration increased the size of the mineral grains and segregated them into bands, a transformation which made the rock and its minerals more stable in ...
