滇东南三保银多金属矿床地质特征

GEOLOGY AND METALLOGENESIS OF THE SANBAO SILVERPOLIMETALLIC DEPOSIT,THE SOUTHEAST YUNNAN

三保银矿是近年新发现的多金属矿床，已初具中型规模，可望发展成为大型矿床。通过矿床地质特征的研究，提出了“层－构－岩－带－相”五字控矿规律，并认为该矿床具有层控性、多源性和多期次的成矿特点，应属变质－岩浆热液叠加改造型层控矿床。

The Sanbao silverpolymetallic deposit is a middlesized one which was found in recent years. It might be enlarged to a largesized deposit. On the basis of geology, the orecontrolling patten of stratumstructuregraniteelement zonationfacies was established. The deposit shows stratabound, multisource and multistage in metallogenic characteristics. It belongs to stratabound deposit with superimposition of metamorphism and magmatic hydrothermal processing.
