摘　　要：1∶5万区域矿产地质调查工作是寻找矿产资源的重要手段。四川盆地西南金阳县一带铅锌矿位于扬子地台西缘,属上扬子中东部Pb-Zn-Ag Cu成矿带,本次结合研究区矿产地质填图成果,对区域地质背景、矿产成矿条件以及控矿地质因素进行细致的研究分析,确定了区内寻找铅锌矿床的有利标志,研究表明区内铅锌矿床分布与地球化学异常套合率高,且受地层岩性、岩相古地理以及构造控制明显,为区内铅锌矿靶区圈定和潜力评价提供地质依据。The geological survey of 50000 regional mineral resources is an important means of searching for mineral resources.The lead-zinc deposits in Jinyang County,southwest of Sichuan Basin,are located in the western margin of the Yangtze platform,belonging to the Pb Zn Ag Cu metallogenic belt in the middle east of the upper Yangtze.This time,combined with the results of mineral geological mapping in the study area,the regional geological background,mineral metallogenic conditions and ore controlling geological factors were carefully studied and analyzed,and the favorable indicators for searching for lead-zinc deposits in the area were determined.The research shows that the distribution of lead-zinc deposits in the area has a high matching rate with geochemical anomalies,and the distribution of lead-zinc deposits in the area is affected by the formation lithology The lithofacies,paleogeography,and structural control are obvious,providing geological basis for the delineation and potential evaluation of lead-zinc ore exploration targets in the area.
