Marble: Metamorphic Rock: Pictures, Definition, Properties
Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO 3 ) and usually contains other minerals, such as clay minerals, micas, quartz , pyrite , iron oxides, and graphite .
Marble - Wikipedia
Marble is a rock resulting from metamorphism of sedimentary carbonate rocks, most commonly limestone or dolomite. Metamorphism causes variable re-crystallization of the original carbonate mineral grains. The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals.

Metamorphic Rock Types: Pictures and Descriptions - ThoughtCo
2019年5月10日 · Marble is made by regional metamorphism of limestone or dolomite rock, causing their microscopic grains to combine into larger crystals. This type of metamorphic rock consists of recrystallized calcite (in limestone) or dolomite (in dolomite rock).
Metamorphic Rocks: Pictures, Descriptions & Identification
There are many different types of metamorphic rocks, and if you know what to look for it can be fairly easy to identify them and distinguish them from other rock types. Metamorphic rocks are typically classified first by their texture and then by their mineral composition and protolith (the rock type they formed from).
