| 摘 要： | 富金斑岩型铜矿床作为斑岩型矿床的一类,自20世纪70年代起逐渐引起了人们的重视.近年来又取得了很多重要进展,主要体现在以下5个方面:①富金斑岩型铜矿不仅在全世界范围内大量发现,而且部分矿床规模巨大;②绝大多数富金斑岩型矿床集中在新生代和中生代产出,尤以第三纪最为普遍;③富金斑岩型铜矿床不仅仅发育于汇聚板块边缘的岩浆弧环境,在大陆碰撞带甚至是陆内环境也发现了大量此类矿床;④含矿斑岩绝大多数为钙碱性岩浆系列,但部分矿床与高钾钙碱性(甚至钾玄质)岩浆密切相关;⑤富金斑岩型矿床金的富集,与大地构造背景、成矿时代、含矿斑岩性质、围岩性质、蚀变与矿化类型等因素关系不大,而主要受地幔岩浆过程、岩浆-热液过程及热液过程控制.

| Abstract: | The gold-rich porphyry copper deposits, one group of porphyry deposits,have aroused much interest among geologists after 1970s. On the basis of previous researches in classification, distribution, geological epochs, regional tectonic settings, intrusive rock compositions, and hydrothermal alteration-mineralization types, a great amount of progresses have been made in recent years, which can be summarized in following five aspects. ① Gold-rich porphyry Cu deposits can be found worldwide and most of them are large scale. ② The most gold-rich porphyry Cu deposits discovered are concentrated in Cenozoic and Mesozoic, commonly Tertiary. ③ Gold-rich porphyry Cu deposits occur commonly in magmatic arc settings at convergent plate boundaries, but a great number of such deposits are found recently in the continental collision belt, even in intracontinental environments. ④ Most of the ore-bearing porphyry are calc-alkaline magmas series, but part of deposits of this kind are closely related to high-K calc-alkaline and shoshonotic magmas. And finally, the enrichment of gold in Cu-rich porphyry-type deposits has little relation with geotectonic setting, metallogenic age, intrusive rock compositions, wallrock composition, hydrothermal alteration-mineralization types, but are controlled by mantle magma process, magma-hydrothermal process and hydrothermal process. |
