摘要：

详细论述了浪全金矿床地质特征, 该矿床为微细粒浸染型金矿床,规模为中型。从矿床地质特征、矿石物质成分、金矿的赋存状态、围岩蚀变、成矿期次以及地层含金性、矿物包裹体、稳定同位素等方面探讨矿床成因,认为浪全金矿床先后经历了沉积、热液和表生3个成矿期富集成矿,矿床主要受地层和断裂构造控制。中三叠统百缝组是主要的矿源层;主要的控矿构造是浪全断裂带,矿体产于构造活动较强部位;热液期可分为4个阶段,金矿化主要与中、低温热液的二、三阶段有关。

Abstract:

The geological features of gold deposit at langquan are described detailedly.With middel scale, this deposit is microfine-grained disseminated gold deposit.From geological features of gold deposit, material composition of ores,hosting status of gold,alteration of wall rocks,metallogenetic epoch as well as gold-bearing proerty of strata,inclusions of minerals,stable isotopes,etc.,the author has discussed the genesis of this gold deposit and considered a hat this deposit underwent sedimentary,hydro thermal and supergene enrichment stages and was controlled by strata and fault structures.The strata of Beipeng Formation of Middle Triassic have high abundance of gold and are the major source beds;The langquan fault zone is the main ore control structure and the ore bodies occur in the stronger active structures;The hydro thermal epoch may be divided in to four stages and the gold mineralization is principally associated with the second and the third stages,namely mesothermal stage and epithermal stage.

Key words: Guangxi, microfine-grained disseminated gold deposit, geological fealtures, discussion on genesis
