The Chemical Composition of Marble Actforlibraries.org
The exact chemical composition of marble will greatly vary dependong on the location and the minerals or impurities present in the limestone during recrystallization. Typically, marble is composed of the following major constituents: 38-42% Lime (CaO), 20-25% Silica (SiO2), 2-4% Alumina (Al2O3), 1.5-2.5% various oxides (NaO and MgO), and 30-32% various carbonates (MgCO3 and others).

What Is the Chemical Composition of Chalk? - Reference
2020-3-27 By Staff Writer Last Updated Mar 27, 2020 1:37:10 AM ET. Chalk is calcium carbonate and has the same chemical composition as limestone, marble, ground calcium carbonate and precipitated calcium carbonate. Chalk, like the other types of calcium carbonate, is in the form of calcite, which is a crystal. Chalk derives from shells of coccoliths or algae.

Formation of Chalk and Marble - Compare Rocks
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes. Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone. 1.2

Difference Between Limestone and Marble Difference
2018-11-6 Limestone is a rock that is formed when mud, sand, and shells are deposited in oceans and lakes and develop into a sedimentary rock. Since it is made up of fossilized particles, it is porous and is soluble in water. It is composed of silica, clay, silt, and sand. It also has many colors and may be crystalline, clastic, granular, or massive.

All limestones contain at least 50% calcium carbonate by weight. Limestones also contain a considerable amount of magnesium carbonate (MgCO3), also known as dolomite. Minor constituents include clay, iron carbonate, siderite, sulfate, feldspar, pyrite, and quartz. Pure limestone is white or almost white.
