| 中文摘要: |
| 文章以成矿系统理论为指导研究了扬子区黔西南金矿成矿系统.扬子区黔西南中二叠统-下三叠统基岩与第四系松散沉积物中的微细浸染型金矿,分别属于中二叠统-下三叠统低温热液成矿子系统和表生成矿子系统,后者为前者风化改造而成,两者共同构成为一个金矿成矿系统--扬子区黔西南金矿成矿系统.初步讨论了该成矿系统的地质背景、成矿要素、成矿作用过程和产物,以及成矿后的变化情况等,重塑了该成矿系统的整体面貌. |
| 英文摘要: |
| Base on mineralization system, disseminated - type gold deposits hosted in the Middle Permian to Upper Triassic basements and lateriric - type gold deposits hosted in Quaternary sediments in the southwest Gulzhou province, southwestern Yangtze block, belong to Middle Permian to Upper Triassic low temperature hydrothermal mineralization subsystem and supergene mineralization subsystem, respectively. The latter was resulted from the former weathered transformation. These two subsystems form a gold mineralization system in the southwestern Guizhou province, Yangtze block. Geological setring, mineralizing factors, process, products and post - mineralized changes are initially discussed. The results have advantageous to comprehensively understand dynamic mechanism of gold mineralization, evolution history and ore space - rime distribution regulation in the area. |
