Both classifications distinguish allochems, matrix or micrite, and sparry calcite cement and both schemes emphasize texture (depositional texture and hence depositional setting). Both are widely used today with some modifications (Embry and Klovan, 1971; James, 1984) to the virtual exclusion of all other limestone classification schemes. Many ...Our data suggest that the limestones of the Taiyuan Formation recorded the REE patterns that are characteristic of chemical precipitation from seawater. Slight …History Original classification. Robert J. Dunham published his classification system for limestone in 1962.

Oolitic limestone is made up of small spheres called ooiliths that Sedimentary rocks are emplaced and then folded. Erosion takes place, followed by more deposition. Be able to order the steps of the formation of a nonconformity. Sedimentary rock layers are deposited and then intruded by a pluton. Erosion exposes the pluton at the surface. Sediments are once again deposited, covering the erosional surface.When base level rises, deposition increases as the stream adjusts attempting to establish a new state of equilibrium. A stream that has approximately achieved equilibrium is called a graded stream. 11.5.5 Fluvial Landforms .
