Limestone

Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common nonsiliciclastic (sandstone and shale are common siliciclastic rocks) sedimentary are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite). Carbonate rocks where the dominant carbonate is dolomite (calcium magnesium carbonate) are ...

The Ponce Limestone is composed of three carbonate sequences of shallowwater deposits that developed on a gently (<3°) dipping ramp environment in response to relative sealevel fluctuations. Facies are dominated by heterozoans and large benthic foraminifera (LBF) along with coralline red algae and cool and turbidwater tolerant photozoan corals (Montastraea, Goniopora, Porites, and Agaricia).
