Marble is a metamorphic rock originated from limestone exposed to high temperatures and pressure. For this reason, the largest deposits of marble are found in regions of limestone bedrock and volcanic activity. Marble is a rock explored for use in construction.

Main Mineralogy – calcite, dolomite

Minor constituents – quartz, pyrite, amphibole, diopside, etc.

Chemical Composition – carbonate (calcite magnesium)

Structure – massive to foliated

Textures – granoblastic, granoblastic polygonizada

Types of metamorphism – regional and contact metamorphism

Main metaderivadas rocks – limestone and dolomite.

Comments – are classified commercially as marble, all carbonate rocks capable of receiving polish. The mineralogical composition depends on the chemical composition of sediments and metamorphic grade. In this way, have a variety of colours and textures, structures that become quite profitable in the industry of ornamental rocks. (By Mark unb Agronomy).

In Portugal, the largest explorations of marble are located around the area of Estremoz.
