Magmatic rock mass and information for large and superlarge mineral deposits and its ore-prospecting effect in deep crust
地壳深部岩浆岩岩基体与大型、超大型金属矿床的形成及找矿效应

Geophysical study based on parts large, super large and polymetallic deposits discover, substance and energy intense exchanges in depths of Earth under the affect of heat power. When hydrothernal (magma) upwelling along channel (shatter belt, weak formation or faults), the mineral elements are congregated in deep suitable position of rock stratum. It is necessary that there are formed large and relatively large in acidity,intermediate acidity and basic-ultrabasic magmatic rock mass at the same time. There these types magmatic rock are carried thermal energy and actuated the deep matter divergence,regulate again replacement, alteration and metamorphism with effect of wall rocks. In this deep process and under environment of medium and structure, mineral elements are congregated nearby the large or relatively large magmatic rock mass and coupling. Thus there are formated large, superlarge and polymetallic deposits.
