Fine-grained carbonates formed in the open ocean from the settling of calcareous plankton.

High photosynthetic activity removes CO2CO sub 2 , shifting the balance to promote CaCO3CaCO sub 3 precipitation. 3. Mechanisms of Formation: Sedimentary Components

When the water became too crowded with minerals, calcium and bicarbonate joined forces, crystallizing directly out of the water like snowflakes in a liquid sky. This formed the first limestones The Biological Revolution: origin of carbonate sedimentary rocks pdf extra quality

The Genesis of Carbonate Sedimentary Rocks: Origins, Pathways, and Diagenetic Evolution

Endolithic algae and fungi bore holes into skeletal grains; these holes fill with fine micrite, destroying internal shell structures.

solubility, triggering precipitation (commonly seen in upwelling zones or springing waters). Autotrophic organisms extract dissolved CO2cap C cap O sub 2 HCO3−cap H cap C cap O sub 3 raised to the negative power , locally elevating pH and inducing carbonate saturation. 2. Controls on Carbonate Production Let me know which or regional case study

Shallow marine environments host the highest concentration of carbonate production.

The two dominant minerals are (CaCO₃) and dolomite (CaMg(CO₃)₂). A rock composed primarily of calcite is a limestone , while a rock where the calcite has been mostly replaced by dolomite is a dolostone (or dolomite rock). It is important to note that carbonate sediments are not merely detrital fragments transported from elsewhere; they are "born" within the depositional environment. They form either through direct chemical precipitation from seawater or as the calcitic or aragonitic skeletons of countless marine organisms.
