Explanation
A metamorphic rock composed of caldte and dolomite, which is formed by carbonatite such as limestone and dolomitite through regional metamorphism or thermal contact metamorphism. Is it generally fine? Coarse grained balastic texture, massive structure, sometimes with banded structure. Due to the different impurities and metamorphic conditions of the original rocks, marble can contain a small amount of metamorphic minerals such as serpentine, forsterite, diopside, tremolite, phlogopite, almandine, wollastonite or quartze. marble are further named in detail according to the types of carbonate minerals, characteristics of metamorphic minerals, special structures and colors. Such as marble, dolomitic marble, wollastonite marble, spotted marble, pink marble, etc. The white marble with pure composition, fine and uniform grain size and density is called "Hanbaishi", and the serpentinized marble is called lamianyu. People with various impurities present in different colors and flowers, which are very beautiful after polishing. marble is an excellent raw material for artistic decorations and building stones. Dali College is widely distributed and abundant in Dali County, Yunnan Province, China, hence its name.
