摘　　要：广东省新兴县都斛铜矿床处于吴川—四会深大断裂的中部边缘带,其铜成矿活动主要受本区燕山期斑岩体和NE向断裂构造双重控制,已发现的脉状铜矿体产状各异,在空间上整体形成一个不规则的环状,单个矿体呈细脉分布在黑云母二长花岗岩中,并具有浸染状矿化分布在花岗闪长斑岩等斑岩型矿床的矿化特征。通过对该矿床成矿地质特征的综合研究,对比粤西地区及国内类似斑岩型矿床的找矿经验,认为都斛铜矿床具有斑岩型矿床地质特征,处于斑岩矿床外围或顶部的脉状矿体带,具有寻找斑岩铜矿的潜力。Douhu copper deposit in Xinxing County of Guangdong Province,is located in the central margin of the Wuchuan-Sihui deep fault zones.The copper mineralization is mainly controlled by the Yanshanian porphyry and NE-trending fault structure in the area.The vein-shaped copper ore bodies have different occurrences,forming an irregular ring in space.A single ore body is distributed in the biotite monzogranite in the form of fine veins and disseminated mineralization is discovered in the granodiorite porphyry.Based on the comprehensive study of the ore-forming geological characteristics of the deposit and the comparison of the prospecting experience of similar porphyry type deposits in West Guangdong and China,it is considered that Douhu copper deposit has the geological characteristics of porphyry type deposit.It is just located in the vein-shaped ore body belt in the periphery or at the top of porphyry type deposit.There is a great potential to explore the porphyry copper deposit in the mining area.
