摘　　要：根据蚀变分带及矿物组合、矿田地球化学分带及元素组合特征,对矿床类型及成矿模型特征进行探讨。成岩与成矿作用在时空上总体具有由西南向东北迁移演化的特点,上厂矿段为中高温Mo(Cu、Pb、Zn)矿→金竹坑矿段为中低温Cu、Pb、Zn(Ag)矿→雷母寨矿段为中低温Ag、Pb、Zn矿。三者从时间、空间、物源等方面有依存关系,以及矿化类型专属性等,可以将矿田矿床划分斑岩型铜钼多金属矿床及火山-次火山热液型铅锌银多金属矿床2个成矿类型,并类比预测矿田矿化类型及找矿方向。Based on the alteration zoning, mineral assemblages, geochemistry zonation and element association characteristics of the ore field, the types of mineral deposits and metallogenic characteristics, it is considered that the diagenesis and ore-forming process take on the characteristics of evolution and transplantation from south-west to north-east in time and space, namely, from the intermediate and high temperature ores such as Mo, Cu, Pb and Zn in the Shangchang ore segment to the intermediate and low temperature ores such as Cu, Pb, Zn and Ag in the Jinzhukeng ore segment and to the intermediate and low temperature ores such as Ag, Pb and Zn in the Leimuzhai ore segment. The Shangchang mining field can be divided into 2 mineralization types of the porphyritic copper and molybdenum polymetallic deposit and the volcano-subvolcano hydrothermal lead, zinc and silver polymetallic deposit according to the dependence relationship of the above-mentioned three type ores in time, space and material source and the special property of mineralizing types. Finally, the author put forward a mineralizing type and an ore-finding target of the ore field by analogy.
