安徽省庐江县朱岗铅锌矿床地质特征及找矿方向
|
摘要
庐江县朱岗铅锌矿床位于庐枞盆地北东部边缘,是近年实施安徽省地勘基金项目新发现的矿床,为一大型规模主要为铅锌矿共生少量铜矿的隐伏矿床,属火山、次火山气—液作用形成的斑岩型铅锌矿床。本文阐述了区域成矿地质背景和矿床地质特征,分析了控矿条件及矿床成因,提出了找矿标志及找矿方向,不仅丰富了该区矿产勘查资料,也为今后寻找类似矿产提供借鉴意义。
The Zhugang Pb-Zn ore deposit,Lujiang County lies at the northeastern fringe of the Lu-Zong basin.It is a new deposit found in recent years as the efforts of a geological exploration fund project of Anhui Province.This is a big concealed ore deposit composed mostly of Pb-Zn ore and less of copper,a deposit formed by a volcanic,subvolcanic gas-liquid process.This paper described regional metallogenic geological setting and geological features of the deposit,analyzed ore-control conditions and genesis of the deposit,showed oreprospecting indicators and direction,adding much to the database of mineral exploration in the area and giving a clue for finding similar deposits in the future.
