Formation of limestone

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO 3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite. Under the conditions of metamorphism, the calcite in the limestone ... .

Explore the ...Limestone has two origins: (1) biogenic precipitation from seawater, the primary agents being lime-secreting organisms and foraminifera; and (2) mechanical transport and deposition of preexisting limestones, forming clastic deposits. Travertine, tufa, caliche, chalk, sparite, and micrite are all varieties of limestone.

Limestone formation began as early as the Archean Eon, more than 2.5 billion years ago. However, the earliest direct evidence of limestone comes from rocks that formed during the Proterozoic Eon, about 1.8 billion years ago.limestone and sandstone (Fig. 7). Principal Mississippian formations in southern Oklahoma (excluding the Ouachi-tas) are the Caney Shale, Goddard Formation, and Springer Formation (which is partly Early Pennsylvanian): these and the underlying Sycamore Limestone are 1,500–6,000 ft thick in the Ardmore and eastern Anadarko Basins and …Friday, May 16, 2014.

Over millions of years these shells collected on the ocean floor. As layers of shells and mud built up, the lower layers slowly hardened into limestone. Limestone is found all over the world. Dover, England, is famous for its white cliffs made of chalk, a soft form of limestone.

It is the most common non-siliciclastic ( sandstone and shale are common siliciclastic rocks) sedimentary rock. Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite).

kelly oubre jr. Limestone, or its metamorphic cousin, marble, is rock made primarily of calcium carbonate. These rock types are often formed from the bodies of marine plants and animals, and their shells and skeletons can be preserved as fossils. Carbon locked up in limestone can be stored for millions—or even hundreds of millions—of years.Another significant region where limestone formation is ongoing is the Bahamas Platform, situated in the Atlantic Ocean about 100 miles southeast of southern Florida.
