Oolitic limestone rock.
Limestone is a sedimentary rock that is usually white in color, as it is largely composed of calcium carbonate. Limestone can be colored by impurities, however; iron oxide can make limestone red, brown or yellow, while carbon can make it gr...
Oolitic limestone. Oolitic limestone is made up of small spheres called ooiliths that are stuck together by lime mud. They form when calcium carbonate is deposited on the surface of sand grains rolled (by waves) around on a shallow sea floor.Question: You are hiking in the Grand Canyon one sunny day and notice a rock sequence consisting of a thick bedded, quartz sandstone with cross- and graded-bedding on top, followed by a layer of black shale containing brachiopod and pelecypod (seashell) fossils below that, followed by a gray, oolitic limestone below that, followed by a layer of chert.Oolitic limestone is a carbonate rock formed from the cementation of thousands of ooids.

Browse Science products at School Specialty!Limestone is a sedimentary rock having more than 50% calcium carbonate in the form of calcite by weight. It also contains some percentage of other materials as well. The chemical composition of pure calcite is CaCO3. The limestone comprises calcite or double carbonate consisting of calcium and magnesium (dolomite).
Limestone rock comes in a variety of forms and names, including chalk, Coquina, travertine, tufa, fossiliferous limestone, lithographic limestone, and oolitic limestone. They have been divided into groups based on how each rock was produced, how it appeared, its content, other variables, and uses of limestone.Rock Type-4 represents good to a very good type of limestone rock (yellow color) where the effective Porosity is more than 0.10 % and Water saturation less than 35%. This type coincides with Microfacies type (Peloidal–oolitic Grainstone Microfacies), FZI-4, Mega port type, and with a low irreducible Water saturation (Swi) in capillary pressure …
