Learning Geology: Submarine Fans
Jul 01, 2015Carbonate shelves can be important sources of sediment redeposited in the ocean basins by turbidites, but the supply of carbonate sediment is rarely focused at discrete points along the continental slope: submarine fans composed of carbonate material are therefore rarely formed, and most carbonate turbidites are associated with slope-apron systems.

Sediments and Sedimentary Rocks
1. Carbonate sediments and sedimentary rocks are formed from the accumulation of carbonate minerals precipitated either organically or inorganically from seawater. The minerals are either calcium carbonate (calcite, aragonite) or calcium-magnesium carbonates (dolomite). Carbonate formation occurs mostly in warm, tropical regions.
