Limestone

2022-1-2 · Description. Limestone (See also Marble and Dolomite) Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate. Limestone varies in colour from cream through whiote to medium dark grey (when freshly broken).

Uses of Marble – Types, Properties and Advantages

Minerals that naturally occur like calcite and rocks like limestone and Marble are examples of inorganic crystalline solids. They depict the multiple faces of Calcium Carbonate. So, all these subclasses of Calcium Carbonate have the same chemical formula. The Marble chips are white limestones that have the same chemical formula CaCo₃.

rock composed marble

Marble is a non-foliated metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Geologists use the term "marble" to refer to metamorphosed limestone; however, stonemasons use the term more broadly to encompass unmetamorphosed limestone.[1] Marble is commonly used for sculpture and as a building material.
