| 摘 要： | 本文以沂南金厂金铜矿田为例,提出本区热液成矿物质的迁移、聚集主要受成矿期构造形变的控制。成矿元素富集于构造变形强烈的部位,并且在变形构造的不同部位存在有不同类型的矿体。另外通过室内岩石力学实验,测取岩石的力学参数,进行应力场的反演,并以渗流力学理论来模拟矿液运移势的分布,从而定量的评价构造的控矿性。

| Abstract: | Taking the Jingchang gold-copper deposit of Yinan county, Shandong, for example, the authors propose that the migration and concentration of ore-forming substances in the hydro-thermal solutions might be mainly controlled by structural deformation taking place during the stage of mineralization. Ore-forming elements are concentrated in the places with strong structural deformation, and there occur different types of ore body in different places of the deformational structures. Besides, the structural control of the ore deposition has been evaluated quantitatively through experimental studies on the mechanics of the rocks, measurements of mechanical parameters of the rocks, inversion of the stress field concerned and simulation of the distribution of the migration potential of ore-forming solutions by use of the theory of infiltration mechanics. |
