| 中文摘要: |
| 通过区域成矿地质背景结合矿产分布特征的总结分析，认为峨眉地幔柱活动是幔源成矿物质来源的重要地质事件，深部岩浆活动为区内成矿提供了另一部分物质来源和重要的热源，断裂和沉积不整合界面是深源成矿流体运移的主要通道；从成矿系列的角度对黔西南金等中低温热液成矿进行了探讨，物源、热源和液源为成矿系列的形成、运移、成矿提供了物质基础，成矿系列与印支—燕山期沉积作用—构造活动—岩浆活动密切相关，初步分析认为黔西南地区金等中低温矿床属南盘江—右江地区燕山期与岩浆活动、沉积作用、构造活动有关的金、砷、锑、汞（铊）矿床成矿系列。通过成矿分析提出本区域横向和纵向找矿方向。 |
| 英文摘要: |
| According to the geological background of regional mineralization and comprehensible mineral distribution features, it’s thought Emei mantle plume activity is an important event of mantle-sourced mineral material origin, the deep magma activity affords others material origin and important heat source for the mineralization in this area, the fracture and sedimentary unconformity interface are the main tunnel of deep mineral fluid migration. In the angle of mineral series, gold and other middle-low temperature hydrothermal mineralization in southwest Guizhou are discussed, material source, heat source and fluid source afford material foundation for the formation, transition and mineralization series. The mineralization has deep relation with indosinian-Yanshan sedimentation-tectonic activity-magmation. It’s thought gold and other middle-low temperature hydrothermal deposits are gold, arsenic, antimony and mercury (thallium) mineralization series which have relation with magmation, sedimentation and tectonic activity of Yanshan period in Nanpanjiang-Youjiang area. The horizontal and vertical prospecting direction are carried out. |
