Limestone environment of deposition
Carbonate depositional settings. (A) Marine environment with a marginal reef separating the forereef from a lagoon; oblique aerial view of a reef system on the coast of Caicos Island. (B) Hot-spring environment with carbonate (travertine) deposits formed of dendritic calcite crystals; spring KL6 at Loburu, Lake Bogoria, in the Kenyan Rift Valley.Fossiliferous limestone often contains information about the environment of deposition, and where the organisms lived (or were deposited). Paleontologists can often examine the fossils and determine the geologic age of the rock.Siltstone. Siltstone is a clastic sedimentary rock that formed from grains whose sized between that of sandstone and mudstone. It can found different environmental conditions different color and textures. Siltstone generally are red and gray color with flat bedding planes. Darker colored siltstone have plant fossils and other carbon-rich matter.

Feb 15, 2023 · Rock deposition. The story of how Grand Canyon came to be begins with the formation of the layers and layers of rock that the canyon winds through. The story begins about 2 billion years ago when igneous and metamorphic rocks were formed. Then, layer upon layer of sedimentary rocks were laid on top of these basement rocks. Description This limestone deposit in the karst of Dinaric Alps near Sinj, Croatia, was formed in the Eocene. Limestone is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate ( CaCO3 ).What do the cross-bedding, presence of crinoids, and oolitic nature of the limestone indicate about the environment of deposition? The depositional environment was a carbonate sand deposited in shallow water. The depositional environment was a reef. The depositional environment was a lake. The depositional environment was a delta and streams.
