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。
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 key word 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 metal-logenic system of gold. Hetai area possessed main geological condition that took place large scale mineralization in the Yanshanian period.
