3-8-2014 · There are three basic types of sedimentary rocks. Clastic sedimentary rocks such as breccia, conglomerate, sandstone, siltstone, and shale are formed from mechanical weathering debris. stone sedimentary rocks, such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution.
Sedimentary rock - Origin of limestones | Britannica
30-4-2020 · Sedimentary rock - Sedimentary rock - Origin of limestones: Limestones originate mainly through the lithification of loose carbonate sediments. Modern carbonate sediments are generated in a variety of environments: continental, marine, and transitional, but most are marine. The present-day Bahama banks is the best known modern carbonate setting.
What Are Sedimentary Rocks? - ThoughtCo
Sedimentary rocks are the second great rock class. Whereas igneous rocks are born hot, sedimentary rocks are born cool at the Earths surface, mostly under water. They usually consist of layers or strata; hence they are also called stratified rocks.Depending on what theyre made of, sedimentary rocks fall into one of three types.
Types of Sedimentary Rock - ThoughtCo
Breccia, pronounced (BRET-cha), is usually listed under sedimentary rocks, but igneous and metamorphic rocks may become shattered, too. It is safest to think of brecciation as a process rather than breccia as a rock type. As a sedimentary rock, breccia is a variety of conglomerate.

Limestone | Types, Properties, Composition, …
During the 1700s, limestone was used for lithography which is when pictures are drawn on stones and then copied to other stones. Because limestone contains the remains of dead organisms, it is considered an organic sedimentary rock. There are rare stone sedimentary rocks that form from the precipitation of calcium carbonate from ocean water.
What are sedimentary rocks? - USGS
Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earths surface. Sedimentary rocks often have distinctive layering or bedding. Many of the picturesque views of the desert southwest show mesas and arches made of layered sedimentary rock.Common Sedimentary Rocks:

Sandstone and limestone are common rocks found throughout the world. They create some of the dramatic landscapes you can find across the U.S. As sedimentary rocks, they share certain similarities. However, their different origins and compositions make them unique.
Uses of Sedimentary Rocks - Civil Engineering
Limestone is a form of sedimentary rock that is composed of calcium carbonate. The organic formation of limestone occurs from the accumulation of decayed coral, shell, algae and fecal. The stone formation of limestone occurs from the precipitation of calcium carbonate from lake and ocean water. Limestone is used for the production of cement.
limestone | Characteristics, Uses, & Facts | Britannica
Limestone, sedimentary rock composed mainly of calcium carbonate, usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.
