Dolomite is a common mineral. It is also known as CaMg (CO 3) 2 and is a type of compact limestone consisting of a calcium magnesium carbonate. In combination with calcite and aragonite, dolomite makes up approximately 2% of the earth's crust. The mineral was first described by and then named after the French mineralogist and …Marine Limestone. Marine limestone can be found in shallow water areas either 30 degrees north of or south of the equator. This includes the Indian Ocean, Caribbean Sea, Persian Gulf, Gulf of Mexico, water around the Pacific Ocean islands, and water within the Indonesian archipelago.

Sebastian Junger investigates.How long does it take limestone to form? Limestone stalactites form extremely slowly – usually less than 10cm every thousand years – and radiometric dating has shown that some are over 190,000 years old. Stalactites can also form by a different chemical process when water drips through concrete, and this is much faster.

The most common chemical sedimentary rock, by far, is limestone. Others include chert, banded iron formation, and a variety of rocks that form when bodies of water evaporate.

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 process of limestone formation typically occurs in shallow, warm, marine environments where the accumulation and compaction of sedimentary materials takes place over long periods of time. Limestone can also form from the evaporation of water in caves and other confined spaces.

Sandstone also commonly known as arenite is a clastic sedimentary rock composed mainly of sand-sized minerals or rock grains of about 0.05mm to 2cm, matrix, cement and pore space. (figure 2). . .
