河南汝阳青岗坪铅锌矿矿体特征及找矿方向

Ore Body Characteristics and Prospecting Direction of Qinggangping Lead-zinc Deposit in Ruyang,Henan

受河南省汝阳南部太山庙花岗岩体影响,汝阳县付店—王坪地区岩浆活动强烈,断裂构造发育,形成了以铅锌钼为主的多金属矿床。本次以汝阳县青岗坪铅锌矿床为研究对象,通过地质测量和工程揭露等方法,探索区域矿床特征,为找矿工作提供指导。结果表明,铅锌矿体主要赋存于近东西向构造带内,呈豆荚状顺带产出,矿体产状北倾,断裂构造是影响矿床分布的主要因素。通过分析该矿床成矿机理,认为该区已发现的铅锌矿体周围及大型钼矿床外围区域仍有较大找矿空间。

Influenced by the Taishanmiao granite body in the south of Ruyang,Henan Province,the magmatic activity in Fudian-Wangping area of Ruyang County is strong,and the fault structure is developed,forming a polymetallic deposit dominated by lead,zinc and molybdenum.This paper takes Qinggangping lead-zinc deposit in Ruyang County as the research object,and explores the characteristics of regional deposits through geological survey and engineering exposure,so as to provide guidance for prospecting work.The results show that the lead-zinc ore bodies mainly occur in the nearly east-west tectonic belt,and are produced in a pod-like belt.The occurrence of ore bodies is northward,and the fault structure is the main factor affecting the distribution of deposits.By analyzing the metallogenic mechanism of the deposit,it is considered that there is still a large prospecting space around the discovered lead-zinc ore bodies and the periphery of large molybdenum deposits in this area.
