岫岩金矿控矿断裂生成定位的边界条件和机理

辽宁岫岩金矿是岩浆热液成因的石英脉型金矿床，然而矿区内的一系列石英脉体尽管其空间分布上关系密切，但其矿化程度却有显著差异。本文就这种差异的原因从区域构造应力场－岩体形态－岩石力学性质－控矿（脉）断裂的性质及时、空定位的相关上进行了深入分析探讨，认为岩体形态、岩石物理力学性质是影响断裂时、空定位和性质的主要因素，而且是控制矿化程度差异的根本因素。井由此推断，在１￣＃，２￣＃断裂带南东侧延伸的深部有望找到矿体。

THE BOUNDARY CONDITION AND MECHANISM OF ORE-HOSTED FAULTS FORMING AND LOCATING IN XIUYAN GOLD DEPOSIT

Through study,wes uggest that Xiuyan gold deposit be of quartz-vein gold deposits ofmagmatic hydrothermal. But the intensity of mineralization of differemt quartz veins largelyvaried in the small area of mining district. The reason of this dif-ference is analysized deeplyby studying the tectonic stress energy-the shape and occurrence of rock mass(metamorphicrock xenolith)-the physical and mechan-ical property-the forming ttime,location and natureof faults. We find that the shape and ocurrence of xenolith and the physical and mechanical ofrock is the crucial factors to that difference,these factors control the forming time,locationand nature of ore-hostedfaults. And as a conclusion,we think that some new ore bodies could be found in thedeepplace of the southeast part of 1#, 2# faulted zone.
