摘要
对金牙金矿田构造地质及地球化学的研究表明,金牙金矿田成矿元素的分布、迁移和富集是受构造运动及构造形迹控制的。巴合背斜总体上控制了成矿元素的分布;而断裂构造则控制了成矿元素异常的分布。矿床(点)毫无例外地分布于断裂构造复合部位的构造围压、最大剪应力和应变能的低值区,严格受北西向构造(体系)控制。
The study of structure and geochemistry in Jinya ore field indicated that the distribution, migration, and accumulation of the ore-forming elements were mainly controlled by tectonization and structural features. The distribution of the anomalous area of the elements was controlled by faults and fractures. All deposits in the ore field are iocated in the intersection of tectonic syntaxis, where the values of the structural confining pressure, the maximum shear stress, and the strain energy are lower. The formation and distribution of the deposits are strictly controlledby NW direction structural system.
