江西范家坳铅锌矿区的成矿构造类型及成矿前景

江西范家坳铅锌矿矿区是由两条主边界断裂控制,其内发育的北东向的脆性剪切破裂带为所夹块体内的P型剪切破裂——北东向压扭性剪节理系,该剪节理带控制着本矿区的矿化（点）的分布.通过构造解析后认为,江西范家坳铅锌矿控矿构造为节理型脆性剪切带,成矿构造类型主要为构造细脉型,本文试图从构造控矿的角度出发,去探讨成矿构造控矿的本质及其内在的成因联系.从该区铅锌矿床成矿构造类型的划分及控矿构造类型的研究,初步讨论了江西范家坳铅锌矿主要矿化异常（点）的成矿前景.

METALLOGENESIS STRUCTURE TYPE AND PROSPECT OF FANJIAAO PB-ZN OREFIELD,JIANGXI

Fanjiaao Pb-Zn orefield in Jiangxi is controlled by 2 main boundary faults,the NE brittle shear fracture zone developed in them is the P type shear fracture in the block between them - NE compression torsion shear joint series. The distribution of metallogenesis （point） in this orefield is controlled by this shear joint zone. According to the analysis of structure, we think the ore control structure of Fanjiaao Pb-Zn de- posit of Jiangxi is the brittle shear zone of joint type, the main metsllogenesis structure type is the structure fine veined type. In this paper, we try to probe into the essence of ore control of metallogenetic structure and the inner genesis connection. According to the classification of metallogenesis structure type and the study of ore control struc- ture type, the metallogenesis prospect of main metallogenesis anomaly （point） of Fanjiaao Pb-Zn deposit in Jian- gxi is discussed preliminarily.
