West Sichuan will be Lala Cotai Copper Mine and Shilong Iron Mine is a well-known mining area in this area, copper, iron ore body produced in albite as the main component of a set of metamorphic complex in the stratigraphic division of the fore-shock Dan Department of Management Group estuary group. The causes of copper, iron ore and the closely related sodium metamorphic complexes have long been debated. The number of the rock is easy to call its name, has been called the angle of rock, granulite, fine Bib Kok porphyry, metamorphic sedimentary rock, altered sodium volcanic rock series; copper, iron ore genesis gas into a high temperature hydrothermal, Sedimentary metamorphism, volcanic rock type that.
