摘要:

河台金矿床产于燕山早期左行直剪作用下形成的韧性剪切带和糜棱岩带中,其成矿地质背景和矿床地质特征都较为特殊,成矿作用过程复杂。分析了成矿物质来源、构造与成矿的关系、成矿物理化学条件、金的迁移、沉淀机制和成矿作用阶段等成因特征,认为:河台金矿床的定位受韧性剪切带等构造因素的控制;成矿物质来源是多源的,但主要来源于震旦系c组地层,其次是来源于深源岩浆热液;矿床成因类型归纳为韧性剪切带中有深源叠加的层控型热动力变质+热液循环富集金矿床。

关键词: 河台金矿, 矿床, 成因特征, 韧性剪切带, 热液循环

Abstract:

The Hetai gold deposit is strictly controlled by ductile shear zone and mylonite zone.On the one hand,both the background of mineralizing and geological charcter of deposit are especial,the other,the process of mineralizing is complicated.The paper begins with the analysis of ore material source,relation between structure an d mineralizing,physiochemical condition of ore formation and transportation-precipition mechanism of gold.The results of research is that the deposit location is controlled by ductile shear zone and ore materials are multi-sourced but primarily by that from Sinian C bed,subsidiarily by magmatic fluid.The metallogenic model is ductile shear zone+thermal dynamic metamorphison + hydrothermal fluid circulation enrichment.

Key words: Hetai gold mine, Deposit, Characters of genesis, Ductile shear zone, Hydrotherm alfluid circulation
