摘　　要：区内发育古生界浅变质岩系和中生界陆相火山岩系,华力西期—燕山期的岩浆活动强烈而频繁,形成一系列的侵入岩和火山岩。依据区域地质和遥感、物探、化探异常研究结果,运用新理论、新技术、新方法在申请工作区开展金及多金属矿调查工作,确定成矿有利地段,圈定找矿靶区,为进一步找矿提供依据,对本区地质特征进行总结,具有十分广阔的找矿远景。Paleozoic epimetamorphic rocks and Mesozoic continental volcanic rocks are developed in this area.Magmatic activities from Variscan to Yanshanian are intense and frequent,forming a series of intrusive rocks and volcanic rocks.Based on the results of regional geology and remote sensing,geophysical prospecting and geochemical anomaly research,new theory,new technology and new method are used to carry out gold and polymetallic ore survey in the application work area,determine favorable metallogenic areas,delineate prospecting target areas,submit for general survey,summarize the geological characteristics of this area,and have a very broad prospecting prospect.
