安徽省处在3个I级构造单元的接合部即华北板块、扬子板块和大别造山带,金矿分布率极广泛,安徽已知金矿床共100余处,按照成矿构造地质不同,安徽境内金矿主要分布在皖北蚌埠、大别山、长江中下游和江南古陆东段等金成矿区带。本文以长江中下游金矿带为例分析安徽省金矿成矿的地质情况、矿床类型及找矿远景区划。
Anhui Province is located in the junction of three I-level tectonic units, namely, the North China Plate, the Yangtze Plate and the Dabie orogenic belt. The distribution rate of gold is very wide. There are over 100 gold deposits in Anhui Province. According to the geological structure of the ore-forming tectonics, Anhui Domestic gold mines are mainly distributed in the gold mineralization zones such as Bengbu, Dabieshan, the middle and lower reaches of the Yangtze River and the eastern section of the southern ancient land in Bengbu, northern Anhui. In this paper, taking the gold ore belt in the middle and lower reaches of the Yangtze River as an example, this paper analyzes the geological conditions, deposit types and ore prospecting zoning of gold deposits in Anhui Province.
