calcitecemented
Calcitecemented refers to sedimentary rocks in which the pore spaces or grain contacts have been cemented by calcite, a calcium carbonate mineral. This type of cement commonly forms during diagenesis when calcium-rich fluids transport carbonate ions and precipitate calcite within pore spaces, binding grains together and reducing porosity.
Formation typically occurs in burial and diagenetic environments. Calcite cement can precipitate from marine pore waters
Effects on rock properties are most notable in porosity and permeability. Calcite cement reduces connected pore
Identification typically relies on thin-section petrography, where calcite cement appears as crystalline bands or pore-filling material,
