摘　　要：元台子银铅锌多金属矿位于兴城首山—大英昌—杨家杖子NW向断裂带与黑风山—梁家沟—季家沟NE向断裂带的交汇部位。银铅锌多金属矿体主要赋存于长城系常州沟组石英岩与燕山早期花岗岩的接触带中,矿体多呈似层状、脉状产出,为热液充填型矿床,成矿与断裂构造与岩浆热液的活动关系密切。该区成矿地质条件优越,是银、铜、钼、铅锌等金属元素的富集区域,找矿潜力较大。The Yuantaizi Ag-Pn-Zn polymetallic deposit is located at the intersection of NW Shoushan Mountain-Dayingchang-Yangjiazhangzi fault zone and NE Heifengshan Mountain-Liangjiagou-Jijiagou fault zone in Xingcheng county. Genetically, it is a hydrothermal filling deposit and ore bodies are layeroid or vein like. On basis of the geological characteristics and geophysical analysis are elaborated metallogenic condition and prospecting potential in the area. Ore bodies occur mainly in the contact of quartzite in Changzhougou formation of Changeheng system and the Early Yanshanian granite intrusion and are closely related to the multiple tectonic activities of the main fault zone and rnagmatic hydrotherrnal activities. The rnetallogenic geological conditions are superior and Ag, Cu, Pb, Zn etc. are concentrated thus here is po- tential for further prospecting.
