通过对湘东北及其邻区的地质背景和铜多金属矿床地质 -地球化学特征的综合研究 ,提出斑岩型和热液脉型铜矿的成矿物质主要来自同含矿斑岩体或岩脉有联系的深部岩浆分异演化而析出的含矿气液流体 ,与此同时 ,含矿斑岩体或岩脉定位—结晶时通过周围受热地下水的对流循环作用 ,还可从围岩中萃取少量成矿物质加入成矿作用。
Based on the comprehensive study of the geologic background and the geo-geochemical characteristics of copper-polymetallic deposits in the northeast and adjacent areas of Hunan Province, it is proposed that the ore-forming materials of porphyry-type and hydrothermal vein-type copper deposits come from the same ore-bearing porphyry or rock At the same time, the ore-bearing porphyry or dikes locate and crystallize through the convective circulation of the surrounding heated groundwater and can also be extracted from the surrounding rock A small amount of ore-forming material added to the mineralization.
