摘　　要：戈塘金矿田地处扬子陆块与华南褶皱带交接部位,包括戈塘大型金矿床与豹子洞、万人洞、苞谷地三个小型金矿床。矿田内探明储量已开采多年接近枯竭,为增加戈塘矿田远景储量,依据矿床后生变化理论,对戈塘金矿田进行基础地质研究。认为戈塘金矿田内的矿床(点)皆为蚀变角砾岩型金矿,成矿主要受古地貌、构造断裂、地下水综合影响,在构造有利位置、热液蚀变强烈、剥蚀程度较低部位是戈塘矿田的重点找矿方向。The Getang gold field is located at the junction of the Yangtze block and South China fold belt,including three small-scale gold deposits of Baozidong,Wanrendong and Baogudi and Getang large-scale gold deposit.The proven reserves in the ore field have been nearly exhausted for the mining in many years.In order to increase the potential reserves of the Getang ore field,the basic geological study of the Getang gold ore field is carried out according to the deposit theory of post variation.The gold mineralization is mainly influenced by ancient terrain,tectonic fracture and groundwater.The favorable position of structure,the strong hydro-thermal alteration and the lower part of denudation is the key prospecting targets and direction.
