| 摘 要： | 通过分析区域成矿作用背景及河台地区加里东-燕山期成矿物质活化、迁移、富集、沉淀条件,认为燕山期华南地幔柱活动对河台金矿的形成起到关键作用,深源流体携带的大量成矿物质是金的主要来源,地幔柱构造、深大断裂、深部构造及韧性剪切带-韧脆性构造构成了完善的金的运移和再富集成矿体系。河台地区在燕山期具备了发生大规模成矿作用的主要条件。

| Abstract: | Based on the analysis of the regional deposit-forming background and the conditions of activation,migration,enrichment and precipitation of ore-forming materials in Hetai area from Caledonian to Yanshanian period,believe that the pulsation and upwelling of the mantle plume in late Yanshanian period in South China plays a keywords on formation of Hetai gold deposit.mass of ore-forming materials caarried by deeply-derived fluid is major source of gold.Mantle plume tectonics,deep big fault belt,deep structure and ductile shear zone,ductile-brittle structure composition perfect migration,enrichment once more and metallogenic system of gold.Hetai area possessed main geological condition that took place large scale mineralization in the Yanshanian period. |
