摘要
新太古代绿岩是鲁西铜石地区金矿的矿源层,矿体主要赋存于寒武系中不纯净的白云岩层和灰岩层中,含矿岩体的侵位主要受区域性大断裂的控制,接触带、滑脱破碎带以及不整合面等构造控制了矿体的空间定位,岩浆的活动是金元素的活化、迁移及富集的主要热源和动力。该区与铜石杂岩体有关的断裂及杂岩体周边的滑脱构造面和不整合面是金矿有利的产出部位,经进一步工作可望有新的突破。
The Neoarchean greenstone is the main ore source bed of the gold deposits in Tongshl area. The orehodies hosted in the impure dolomite and limestone layers in Cambrian. The emplacement of ore-formlng intrusions was controlled by regional faults,and the orebodies were controlled by the structures of contact zones, detachment fault zone and unconformity surfaces. Magmatie activities provided the heat and power for the activation, migration, enrichment of Au. In the area, the faults and detachment structure and unconformity surfaces related to the Tngshi intrusive complex are often the spots favorable for ore-forming. The new breakthrough can be reached with the further study.
