东天山觉罗塔格成矿带成矿系列及成矿谱系

Minerogenetic Series and Lineage in Jueluotage Metallogenic Belt of East Tianshan

据矿床成矿作用差异,划分了12个三级矿床类型和20个四级矿床类型,其中斑岩型铜、钼矿,基性-超基性岩型铜镍矿,海相火山气液型铁、铜、铅锌矿,动力变成(动力热液)型金矿为成矿带内最具找矿潜力的矿床类型。基于成矿带构造演化及矿床在空间、时间上的分布及物质组成特征,划分为6个成矿系列,10个亚系列,其中以与海相火山作用有关的铁、铜、铅、锌等矿床成矿亚系列,与中酸性侵入岩建造有关铁、铜、钼、金、银等矿床成矿亚系列,与镁铁-超镁铁岩有关铜、镍矿床成矿亚系列,与花岗岩建造有关钼、稀有金属成矿系列最具找矿潜力。不同矿床成矿系列间具一定成因联系,不同成矿系列可以彼此复合,共同组成成矿带成矿谱系。

According to the difference of the mineralization of the deposits,there are There are 12 tertiary deposit types and 20 quaternary deposit types,including porphyry copper and molybdenum,basic-ultrabasic rock-type copper-nickel deposits,marine volcanic gas-liquid iron,Copper,lead-zinc ore,and the power-driven(hydrothermal)type gold ore is the type of ore deposit with the most prospecting potential in the metallogenic belt.Based on the tectonic evolution of the metallogenic belt and the spatial and temporal distribution and material composition characteristics of the deposit,six metallogenic series and 10 sub-series are divided.Among them,the ore-forming sub-series of iron,copper,lead,zinc and other deposits related to marine volcanism,the ore-forming sub-series of iron,copper,molybdenum,gold and silver deposits related to the formation of intermediate acidic intrusive rocks and Sub-magnesite related copper and nickel ore deposits in the sub-series,and molybdenum and rare metal mineralization series related to granite construction have the most prospecting potential.Different metallogenic series can be combined with each other to form the metallogenic spectrum of the metallogenic belt.
