Limestone environment.

Limestones may be divided on the basis of their depositional environments into three categories: 1) platform, 2) basin, 3) geosynclinal. Platform limestones are thin, widespread, light colored, fossiliferous limestones which are often dolomitized. Basin limestones of the open basin type are lithologically similar to platform limestones, but ...They are usually located at or near where the land meets the sea. Transitional sandstone environments include deltas beaches, lagoons, tidal flats, salt marshes, and barrier islands. Delta is a sandstone marine depositional environment located at the mouth of a river. Possible cross-beds and ripple marks characterize it.This layer formed as a result of meteorite explosion on the Yucatán Peninsula in Mexico. The event marks the end of the Mesozoic Era and is associated with the mass extinction that also ended the reign of dinosaurs. Dark gray spots are chert nodules and the boulders on the coast are also made of this rock type. Limestone forms in a deep marine environment from precipitation of calcium carbonate. Shale is made of fine clay particles, and therefore indicates deposition in relatively still water. In contrast, sandstone is made of slightly larger grains and therefore deposition of sand can happen in water that is moving slowly.
