The Geological Society of ...Limestone can contain various types of fossils, ranging from microfossils to macrofossils, depending on the depositional environment and age of the rock. Microfossils found in limestone can include foraminifera, coccoliths, and diatoms, while macrofossils can include shells of marine invertebrates such as mollusks, bryozoans, and corals.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.

A series of sedimentary beds is deposited on an ocean floor. The sediments harden into sedimentary rock. The sedimentary rocks are uplifted and tilted, exposing them above the ocean surface. The tilted beds are eroded by rain, ice, and wind to form an irregular surface. A sea covers the eroded sedimentary rock layers.Abstract. Limestone, a major part of the global sedimentary succession, susceptible to post-depositional diagenesis. Studies of limestone geochemistry are essential in the discrimination of tectonic settings of basins in which the limestones were deposited.

Within the Mescal Limestone, algal stromatolites form a conspicuous biostrome, commonly 20–25 m thick. The basal 1–5 m of the biostrome …Limestone forms in a deep marine environment from precipitation of calcium carbonate. Shale is made of fine clay particles, and therefore indicates deposition in relatively still water. In contrast, sandstone is made of slightly larger grains and therefore deposition of sand can happen in water that is moving slowly.

Sedimentary rocks can tell us a great deal about the environmental conditions that existed during the time of their formation. Make some inferences about the source rock, weathering, sediment transportation, and deposition conditions that existed during the formation of the following rocks.They are a product of deposition from a slowing current (Figure 6.4.4 6.4. 4 ). Most graded beds form in a submarine-fan environment (see Figure 6.4.1 6.4. 1 ), where sediment-rich flows descend periodically from a shallow marine shelf down a slope and onto the deeper sea floor. Some graded beds are reversed (coarser at the top), and this ...
