摘要
综合分析了个旧南部地区区域构造演化、火山沉积作用及花岗岩与成矿的关系 ,推断成矿过程实际上是由于区域构造应力的作用 ,导致花岗岩的侵入 ,花岗岩入侵一方面为成矿提供了大量的成矿物质 ,为主要的成矿物质源 .另一方面强大的侵入体是“热动力泵”或“动力源” ,它所产生的热量和动力活化并萃取了地层和基性岩层中的有用金属元素 ,与岩浆后期的含矿热液构成混合矿浆溶液 ,在上升运移过程中 ,在有利的构造部位和有利的地层层位中形成锡铜铅多金属矿床 (体 )
The relationship between the regional tectonic evolution, volcano-sedimentary, granite and metallogenesishe is synthetically analyzed. It comes to the conclusion that the process of mineralization acted by the driving force from region tectonics stress is granite intrusion. On the one hand, the granite intrusive provides a lot of metallogenetic materials as the source of metallogenetic material, on the other hand, as the thermo-source or thermo-dynamic source, it produces the thermo-energy and driving-force to extract the metallogenetic elements from strata and basic volcano, which blends the ore-bearing fluid to form the compounding ore paste. And the orebody forms in the propitious structure and strata during the course of ascending migration.
