Marble Rock


Marble rock can be either regional or contact metamorphic rock. 

That means it can form by rising temperatures and pressures, or by heat only.





The main mineral it consists of is calcite (there is also a dolomitic version that consists of dolomite).

Other minerals - impurities - include quartz, mica, pyrite, iron oxides and graphite.

More rarely sphene, tourmaline, epidote, zoisite, spinel, garnet, albite, labradorite, tremolite and/or diposide can also be present.

So unless it's white and consists of calcite only, some impurities are giving it a different colour.

It has a crystalline structure and it is soft, much softer than quartz, which can look similar. It has a fine to coarse texture.

It forms from limestone (or dolomite - the dolomitic version).

It is easy to distinguish from quartz by trying its softness or testing it with HCl - it reacts to the acid.

Due to its softness it is perfect to sculpture and has been sculptured since ancient times.
