    摘要:

    广西大厂铜坑矿床位于桂西北丹池锡多金属成矿带中段,是国内外著名的超大型锡多金属矿床。该矿床由上部锡多金属矿体和新发现的深部矽卡岩型锌铜矿体组成,前人对上部锡多金属矿体的矿化特征和成矿作用等进行过大量研究,但对层状锡多金属矿体的成因分歧较大,且对深部锌铜矿体研究较少。本文在详细的野外地质调查基础之上,结合前人勘查成果及研究分析,对铜坑矿床地质特征、矿石特征及矿床成因等进行了初步的分析研究,认为铜坑矿区存在泥盆纪海底喷流沉积成矿作用,燕山晚期成矿作用的叠加改造是矿床形成的主要事件。

    Abstract:

    The Dachang Tongkeng deposit in Guangxi is located in the middle of Danchi Tin polymetallic metallogenic belt in northwest Guangxi.It is a famous super-large Tin polymetallic deposit at home and abroad.The deposit is composed of the upper Tin polymetallic ore body and the newly discovered deep skarn type Zinc-Copper ore body. Previous researchers have conducted a lot of studies on the mineralization characteristics and mineralization of the upper Tin polymetallic ore body, but there are big differences on the genesis of layered Tin polymetallic ore body, and there are few studies on the deep Zinc-Copper ore body.Based on the detailed field geological survey, combined with the previous exploration results and research analysis, this paper conducts a preliminary analysis on the geological characteristics, ore characteristics and genesis of the Tongkeng deposit, and believes that the Devonian submarine spray exists in the Tongkeng mining area. the superposition of the late Yanshanian mineralization is the main event of deposit formation.
