How are limestone rocks formed.

Limestone. Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common non-siliciclastic ( sandstone and shale are common siliciclastic rocks) sedimentary rock. Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite). Limestone is a sedimentary rock, formed by the settling and consolidation of deposited materials. Sedimentary rocks are formed from deposits of material which has originally come from living organisms (chemical/organic sedimentary rocks) or from material derived from weathering and erosion of older rocks (clastic sedimentary rocks).Limestone is a sedimentary rock made almost entirely of fossils. Fossils are the remains of ancient plants and animals, like an imprint in a rock or actual bones and shells that have turned into rock. Fossils are found in sedimentary rocks and hold the clues to life on Earth long ago. Limestone: You humans would know so little without rocks ...Updated on December 01, 2019. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. In its pure form, marble is a white stone with a crystalline and sugary appearance, consisting of calcium carbonate (CaCO 3 ). Usually, marble contains other minerals, including quartz, graphite, pyrite, and iron oxides.Dolomite, also known as "dolostone" and "dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater. Dolomite and limestone are very similar rocks.

Limestone. Limestone is a sedimentary rock consisting of more than 50% calcium carbonate ( calcite - CaCO 3 ). There are many different types of limestone formed through a variety of processes.
