Chat OnlineThough ancient limestones and dolomites are composed of calcite and dolomite respectively other calcite group minerals such as magnesite (MgCO 3) rhodochrosite (MnCO 3) and siderite (FeCO 3) occur in limited amounts in restricted environments.
Chat Online· Calcite readily dissolves in diluted hydrochloric acid or vinegar. It is also slightly soluble in water which causes dillution and reprecipitation of calcite along fissures in limestone rocks. These processes lead to the formation of karst landscape with famous caves and dripstones. Similar processes cause the corrosion of concrete.

Chat Online· The key difference between limestone and chalk is that the limestone contains both minerals calcite and aragonite whereas chalk is a form of limestone which contains calcite.. Limestone is a type of sedimentary rock mainly contains different crystal forms of calcium carbonate. Therefore this mineral is highly alkaline. Chalk is a form of limestone.
Chat Online· 5.1 Limestone 5.1.1 Composition The main component of limestone is calcium carbonate (CaCO3) also known as calcite which is formed by the compaction of the remains of coral animals and plants on the bottoms of oceans. It varies from a soft white substance (chalk) to a very hard substance (marble). Most commercial limestone deposits are a brownish
Chat Online· Calcite limestone and marble. Calcite A mineral consisting largely of calcium carbonate (CaCO3 ). Next to quartz it is the most abundant of the Earth s minerals. Crystallizing in the hexagonal system calcite is noted for its wide variety of crystalline forms. Calcite is colourless or white when pure but it may be of almost any colour

Chat OnlineDolomitic limestone is a type of rock that includes up to 50 dolomite. Normal limestone is primarily made up of calcite and aragonite but dolomite forms in the stone when the calcium ions in the calcite part are replaced by magnesium ions — this process is called dolomitization.

Chat OnlineCalcite can form rocks of considerable mass and constitutes a significant part of all three major rock classification types. It forms oolitic fossiliferous and massive limestones in sedimentary environments and even serves as the cements for many sandstones and shales. Limestone becomes marble from the heat and pressure of metamorphic events.
