摘要
广东省连州市坑头冲锡多金属矿位于郴州-怀集大断裂带北东构造带与大东山—贵东东西向构造岩浆带的交汇处,通过对矿区地质、构造、矿床地质特征等进行分析,工作区锡多金属矿主要分布于三叠系下统大冶组(T1d)当中,圈定了8条锡矿(化)体,对区内矿(化)体有了新的认识和前景评价。综合分析矿床分布特征,矿床类型可分为锡石—矽卡岩类(风化残积型、矽卡岩型),锡石—碎裂岩类(构造破碎带型)。初步认为工作区地质条件优越,找矿潜力较大,具有较好的找矿前景。
Kengtouchong tin polymetallic ore deposit in Lianzhou City, Guangdong Province is located at the intersection of the northeast structural belt of Chenzhou Huaiji great fault zone and the east-west tectonic magmatic belt of Dadongshan Guidong.Through the analysis of the geology, structure, and geological characteristics of the deposit, the tin polymetallic ore deposits in the working area are mainly distributed in the lower Triassic Daye Formation(T1d), and eight tin ore(chemical) bodies are delineated,A new understanding and prospect evaluation of the ore(chemical) bodies in the area have been made. Based on the comprehensive analysis of the distribution characteristics of the deposits, the types of the deposits can be divided into cassiterite skarn(weathering residual type, skarn type) and cassiterite cataclastic rock(structural fracture zone type). It is preliminarily believed that the geological conditions in the working area are superior, the prospecting potential is large, and the prospecting prospect is good.
