摘要
庐江县龙冲铁硫矿床位于长江中下游地区庐枞盆地北东部,是近年实施安徽省地勘基金项目新发现的矿床,是一个由中型硫铁矿、小型磁铁矿组成的隐伏矿床,属燕山早期火山堆积-潜火山热液交代的硫、铁复合矿床。本文阐述了区域成矿地质背景及矿床地质特征,分析了控矿条件及矿床成因,提出了找矿标志和找矿方向,不仅丰富该地区矿产勘查资料,也为今后寻找类似矿产提供借鉴意义。
The Longchong pyrite deposit in Lujiang County is located in the eastern part of the Lu-Zong basin in the middle and lower reaches of the Yangtze River.It is a new deposit discovered under the Anhui geological exploration fund project in recent years.As a concealed deposit,it is composed of medium-size pyrite and small-size magnetite ore bodies,belonging to sulfur-iron composite deposit formed by volcanic accumulation and subvolcanic hydrothermal metasomatism in the early Yanshan period.This paper discusses the regional metallogenic geological background and geological characteristics of the deposit,analyzes the ore-controlling conditions and the genesis of the deposit,and puts forward the prospecting indicators and prospecting directions,not only adding to the mineral exploration data on this area,but also providing reference for the future prospecting of similar minerals.
