?How is marble formed

Scientific definition of marble
Scientific definition of marble: it is a type of metamorphic rock that is the result of the regional transformation of clayey limestone and dolomite rocks. In weak and medium grades, dolomite also turns into marble like calcite, provided that there is no silica in the environment. As a result of metamorphism of limestones that are composed of pure calcite, only the grain size becomes larger. According to the above definition, marble, porcelain or crystal, onyx and marble are in this group.
  Standard definition
Marble refers to a group of limestones that have recrystallized under the influence of regional metamorphism or are the result of changing the temperature and pressure conditions of travertines during crystallization.

Marble stones are limestone formed from the deposits of warm and infinite seas and combined with granite millions of years ago. Marble has veins and fossils that give this stone a special beauty. Marble has chains called stylolites, which can be seen in the texture of the stone like heart rhythms. Due to the presence of impurities, this stone can be seen in light to dark colors such as: cream, red, brown, pink, black, mustard, green, etc. Marbles are suitable for facades and carpet floors inside and outside the building. One of the best marble stones can be extracted from the mines of India.
By carefully studying this stone and conducting petrographic tests, the stone texture is completely composed of carbonate minerals, and the main minerals of the stone include calcite, aragonite, and iron carbonate.
Uses of Traunix stone:
Travinix is used in construction for both external and internal facades of buildings such as stairs, floors, columns, walls and facades, etc.
