Details of Marble Stone

             Marble is a metamorphic rock composed chiefly of recrystallised limestone. It is characterised by a granulous texture but the grain size shows considerable variation in different varieties. It varies from finely sachhroidal to highly coarse grained. Marble shows a banded structure.
Composition:- Marble is composed chiefly of mineral calcite in its recrystallised form. Small amount of many other granular mineral like olivine,serpentine,garnet and some amphiboles are also present in many varieties, which are derived from the impurities present in the original limestone present in it during the process of metamorphic recrystallisation.
Varieties:- various types of marbles are distinguished on the basis of their colour,composition and structure
Origin:- Marble is formed from contact of carbonate group of sedimentary rocks. Pure white marble results from pure limestone; coloured marbles from those limestone that have some impurities and dolomitic marble from magnesian limestones.
Uses:- Marble is commonly used in the construction of palatial and monumental buildings in the form of blocks, slabs,arches and in the crushed form as chips for flooring. Because of its restricted occurrence and transport costs, it is mostly used as ornamental stone in costly construction.
