鄂东南地区铜金矿找矿方向

Discussion on prospecting direction of copper and gold depositsin Southeast Hubei

鄂东南地区是我国重要矽卡岩型铁、铜、金矿成矿区之一,位于长江中下游铁铜成矿带大冶—九江铜金成矿带的西段。区内岩浆岩活动强烈,种类较多,大小侵入体达50个之多,众多小岩体及其周围形成铜金矿床(点)。依据鄂东南地区成矿地质条件及成矿规律,结合区内地球物理、地球化学找矿成果,以在小岩体周围寻找接触交代矽卡岩型铜矿床和热液充填蚀变岩型金矿床,指导该区铜金矿找矿工作。

Southeast Hubei is one of the important skarn-type iron,copper and gold ore-forming areas in China,which is located at the western part of Daye-Jiujiang copper-gold metallogenic belt in the middle and lower reaches of Yangtze River.Magmatic rocks in the area are active and have many types,with as many as 50 large and small intrusions,and many small rock bodies and their surrounding areas form copper-gold deposits(spots).According to the geological condition and regularity of mineralization in Southeast Hubei,combined with the geophysical and geochemical prospecting results in this area,the purpose is to explore for the contact metasomatic skarn type copper deposits and hydrothermal filling altered rock type gold deposits around the small rock mass,and to guide the prospecting work of copper and gold deposits in this area.
