九瑞矿集区金鸡窝矿区热液型层控式矿床地质特征
|
摘要
金鸡窝矿床是近些年赣西北大队在已探明的城门山大型铜矿床的边深部查明的大型铜矿床,通过以往以及现阶段的工作成果,重新分析、总结矿区热液型层控式矿床的矿体成矿地质条件、矿床地质特征以及矿石特征,研究其控矿因素、矿化富集规律。通过宏观、微观的矿石特征对其成矿过程进行初步探讨,明确岩体热液中心为成矿物质来源,矿床受热液中心控制走向延伸规模,受黄龙组与五通组平行不整合面、层间破碎带、化学差异面制约及富集成矿,矿床具有矿化分带特征、多期次交代特征以及强烈侵入特征。
Jinjiwo deposit is a large-scale copper deposit identified by Northwest Jiangxi Geology Team in recent years,where is in the deep and edge of Chengmenshan largee-scale copper deposit. Based on the past and the present stage of work results,this paper sums up metallogenic geological conditions of hydrothermal stratabound ore deposit,deposit geological characteristics and ore features,to research ore-controlling factors,mineralization enrichment regularity. The metallogenic process is preliminarily discussed through macro and micro ore characteristics. It is clear that the hydrothermal center of rock mass is the source of metallogenic material. Deposit scale of extension is controlled by the magmatic hot liquid. There is a interface of parallel unconformity,fracture zone and chemical differences in middle of Huanglong Formation and Wutong Formation,which restrict and enrich ore. Deposit with mineralization zone which is the typical characteristics of hydrothermal ore deposit,multistage metasomatism and strong invasion.
