广东省揭西县金坑铜锡铅锌矿位于惠阳—梅县新华夏构造体系之莲花山深大断裂带，矿体受断裂控制，呈脉状产于上侏罗统高基坪群火山岩层间滑动带。通过对该矿床地质及地球化学特征研究，认为该矿床成矿物质来源主要是地壳同熔型花岗岩，热液来源与花岗岩关系密切，是岩浆期后热液裂隙充填(交代)型矿床。
廣東省揭西縣金坑銅錫鉛鋅礦位于惠暘—梅縣新華夏構造體繫之蓮花山深大斷裂帶，礦體受斷裂控製，呈脈狀產于上侏囉統高基坪群火山巖層間滑動帶。通過對該礦床地質及地毬化學特徵研究，認為該礦床成礦物質來源主要是地殼同鎔型花崗巖，熱液來源與花崗巖關繫密切，是巖漿期後熱液裂隙充填(交代)型礦床。

Jinkeng copper-tin-lead-zinc deposit in Jiexi County,Guangdong Province is located in the Lianhuashan deep fault belts of Huiyang-Meixian Neocathaysian tectonic system.The ore bodies that con-trolled by fractures,are occurred as veins in the interlayer-gliding belt of volcanic layers of Gaojiping For-mation,upper Jurassic.By studying on the characteristics of geology and geochemistry of the deposit,it is concluded that the source of the ore-forming materials are related to the I-type granitic bodies,the hydro-thermal source is closely to granite.The deposit belongs to post-magmatic hydrothermal deposit of fissure filling (metasomatism)type.
