Unusual intraclastic limestones in Lower Triassic

These intraclastic conglomerates are believed to have formed from lithified seafloor that was broken into clasts by storm events (Sepkoski Jr., 1982).

Characteristics and controlling factors of carbonate

2015-3-1  The intra-platform shoal deposits consist of intraclastic limestones with visible intraclastic grains. The reservoir of 5468–5486 m of the Yingshan Formation is composed of intraclastic limestone interbedded with argillaceous limestone and micrite limestone. This may be interpreted to have been caused by frequent changes in hydrodynamic conditions during deposition.

Mixed siliciclastic and carbonate sedimentation within

Intraclastic limestone, thin fossiliferous limestone, and oolitic limestone interbedded with fissile shale are characteristic of the Nolichucky Shale (Upper Cambrian) in the Whiteoak Mountain thrust sheet, eastern Tennessee. These lithologies are interpreted as slope and basinal units deposited in water depths that may have exceeded 250--300 m.

Limestone Types, Properties, Composition,

Lithographic limestone is a type of limestone that contains fossils. Powered limestone is used in coal mines as a safety precaution because it absorbs pollutants. It can also be used on roofs to prevent or reduce weather or heat related roof damage. Its turns into the metamorphic rock marble when subjected to high amounts of pressure and heat.

How are Different Rock Types Formed

2021-5-3  Limestone is sometimes partly formed of coral, in fragments or in reefs. Fossils are plentiful in limestone, particularly those of shell-fish, the shells of which sometimes form the greater part of the stone. The hardness of limestone is close to that of calcite (for which H=3) of which it mostly consists. Its specific gravity is from 2.7 to 2.9.
