What are limestone made of

The limestone is mostly made up of one of two types of mineral - calcite or aragonite. Both of these are different crystal arrangements of calcium carbonate (CaCO3). All limestones contain at least 50% calcium carbonate by weight. Limestones also contain a considerable amount of magnesium carbonate (MgCO3), also known as dolomite..

According to the caller, the mysteries had actually been solved by Joseph Davidovits, director of the Geopolymer Institute in St. Quentin, France, more than two decades ago. Davidovits claimed that the stones of the pyramids were actually made of a very early form of concrete created using a mixture of limestone, clay, lime and water.Igneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the molten rock solidifies.Intrusive ...Marble is formed from limestone when the limestone is affected by heat and high pressure during a process known as metamorphism. During metamorphism the calcite limestone recrystallizes, forming the interlocking calcite crystals that make u...

stromatolite, layered deposit, mainly of limestone, formed by the growth of blue-green algae (primitive one-celled organisms). These structures are usually characterized by thin, alternating light and dark layers that may be flat, hummocky, or dome-shaped.

Dolostone is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO3)2 CaMg ( CO 3) 2. Dolomite contains nearly equal amounts of magnesium and calcium. Most dolomites formed as a magnesium replacement of limestone or lime mud before lithification. Rock Composition Limestone is primarily made of the mineral calcite and aragonite. Both these minerals are different crystallized forms of calcium carbonate. The calcite is limestone and often contains some magnesium in it. Calcite in limestone is divided into two types based on magnesium content. The dividing point is 4% magnesium content.Common Metamorphic Rocks: Common metamorphic rocks include phyllite, schist, gneiss, quartzite and marble. Foliated Metamorphic Rocks: Some kinds of metamorphic rocks -- granite gneiss and biotite schist are two examples -- are strongly banded or foliated.
