Question: What Rock Is Marble?

This reaction can only occur when a rock is composed of the mineral calcite (CaCO3).

Is marble an igneous rock?

Is marble a rock or a stone?

Marble is a metamorphic rock that is created as a result of the metamorphosis of a combination of rocks under intense pressure and temperatures. These rocks include calcite, limestone, dolomite and serpentine. The main component of marble is calcium carbonate and contains acidic oxide.

Does marble contain quartz?

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 (CaCO3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.

What is unique about marble?

Unlike granite and other natural stone types, marble is a softer stone. Marble is naturally more porous, which makes it softer. Since it is softer than other stone types, it makes it a great material for sculptures.
