Chemical Sedimentary Rocks - CliffsNotes

Limestones. The most common chemical sedimentary rock is limestone. Composed mostly of the mineral calcite (CaCO 3), limestones are usually formed by biochemical processes in shallow seawater. Coral and algae are especially important limestone builders. Oolitic limestones form in ocean shallows from the accumulation of oolites, sand‐sized spheres of chemically precipitated calcite that ...

Organic Matters of Limestones

Such formations, peculiarly favorable for ore, are rocks easily crushed by movements of disturbance, readily permeated by circulating-waters, and, from their chemical composition, rapidly attacked by solutions carrying carbonic acid. Where situated at the surface, they are cavern-forming limestones.

Schist - Wikipedia

Such rocks as limestones, dolomites, quartzites, and aluminous shales have very definite chemical characteristics that distinguish them even when completely recrystallized. The schists are classified principally according to the minerals they consist of and on their chemical composition.

Oolite - Sedimentary Rocks

Ooids occurring in Ordovician limestone in Estonia are strikingly similar in chemical composition, internal structures and REE (rare earth elements) distribution to modern iron-bearing ooids described from a vicinity of volcanically active island in Indonesia 3. Oolitic limestones form prolific oil reservoirs.

limestone | Characteristics, Uses, & Facts | Britannica

Limestone, sedimentary rock composed mainly of calcium carbonate, usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.

The chemical composition of pure limestone approaches the theoretical composition of calcite (56 percent CaCO and 44 percent CaCO 2). Limestones in which the content of MgO is between 4 and 17 percent are called dolomitic limestones. As the magnesium content increases, limestones pass through a series of intermediate varieties into the dolomites.

Limestone - Sedimentary rocks

Chalk (upper left) is a marine limestone consisting of tests of microscopic algae and foraminifera. Tufa (upper right) is a chemical precipitate of calcium carbonate. Fossils are very common in marine calcitic sedimentary rocks. Rocks such as coquina are wholly composed of fossils but so-called normal limestones may be also highly fossiliferous.
