滇东黔西大中型层控锑汞矿床的类型及其若干地质评价准则

The Kinds of Large and Middle Strata-Bound Sb-Hg Ore Deposits in Eastern Yunnan and Western Guizhou and Discussion on Their Geological Valuation Criteria

本文在对滇东黔西10余个主要大中型层控锑汞矿床详细解剖和分类研究的基础上,从控矿构造、地层和岩石组合、岩相古地理、围岩蚀变、成矿的多阶段性、有用组分的复杂性、同位素、包裹体、主要成矿元素和微量元素、REE元素等方面总结出10项评价大中型层控锑汞矿床的标志和准则,并指出了这些准则在找寻和评价层控锑汞矿床规模时的作用和意义。

Based on the Detailed analysis and Classification researches on more than ten main large and middle strata-bound Sb-Hg ore deposits in eastern Yunnan and western Guizhou t ten standards and criteria for valuating large and middle strata-bound Sb-Hg ore deposits have been summed up from ore-controlling structures, strata and rock associations, litho-facies paleogeography, wall rock alterations, multi-stages of mineralization, complexity of useful components, isotope, inclusions, main ore-forming elemepts and trace elements, REE element, etc. , pointing out the effect and significance of these creteria in prospecting for and valuating the scales of strata-bound Sb-Hg deposits.
