广东省英德官渡镇陈村金属矿地质特征与成因探讨

Geological characteristics and Genesis of Chencun Metal Deposit in Guandu Town,Yingde,Guangdong Province

矿区位于粤北山字型构造前弧东翼南部边缘地区,与佛岗岩所代表的纬向构造带相交接的部位,区内不同强度地发育有粤北系、经向带、纬向带、新华夏系的褶皱、断裂、劈理和破碎带,构造较为复杂。最主要的构造线以"翁江复向斜"为代表,呈北东向,广泛分布的主要是上古生界地层。矿体产出受断裂构造影响,并受火山热液的叠加,通过对矿体特征、矿石质量的分析论述,认为该矿床为多金属矿床。

The mining area is located in the southern edge of the eastern wing of the forearc of the northern Guangdong mountain type structure,and intersects with the zonal structural belt represented by the Fokangyan.There are different strengths of the northern Guangdong system,meridional belt,zonal belt,fold and fault of the New Huaxia system.Cleavage and fracture zone,the structure is more complex.The main tectonic line is represented by Wengjiang compound oblique,which is north to east and widely distributed in Upper Paleozoic strata.The ore body is influenced by fault structure and superposed by volcanic hydrothermal solution.Through the analysis of ore body characteristics and ore quality,it is considered that the ore deposit is a polymetallic deposit.
