How does fossil containing limestone form.

Chert (/ ˈ tʃ ɜːr t /) is a hard, fine-grained sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO 2). Chert is characteristically of biological origin, but may also occur inorganically as a chemical precipitate or a diagenetic replacement, as in petrified wood.. Chert is typically …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.According to Discovering Fossils, chalk occurs naturally in nature as calcium carbonate, a form of limestone.

In chemical sedimentary rocks, the process is ...Apr 23, 2023 · Chemical composition and properties of limestone. Limestone is primarily composed of calcium carbonate (CaCO3) in the form of the mineral calcite. It may also contain other minerals such as dolomite (CaMg (CO3)2), clay minerals, and other impurities. The purity of limestone depends on the geological conditions under which it formed. 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.
