摘要
东杨泉地区位于鲁西地块尼山凸起东南部,紧邻龙宝山杂岩体,成矿条件优越。为进一步分析东杨泉地区找矿前景,通过梳理以往区域地质资料和矿区地层、构造、岩浆岩和地球化学等调查结果,总结了东杨泉地区金多金属矿成矿地质特征,并与周边已有矿床的对比研究。研究结果表明,矿区出露寒武系地层是中低温热液型矿产的有利赋矿地层,以北西向为主的断裂构造发育;银、铅、金等元素异常规模较大,异常套合较好;燕山期岩浆活动为有益元素的运移提供了物源、热源和动力。东杨泉地区与龙宝山金矿具有极为相似的成矿环境,具备良好的成矿物质来源和活化、迁移、富集条件,中低温热液型金及金属矿床找矿前景较好。
Dongyangquan area is located in the southeast of Nishan Uplift of West Shandong block,close to Longbaoshan complex,and has superior metallogenic conditions.In order to further analyze the prospecting prospect of Dongyangquan area,the metallogenic geological characteristics of the gold polymetallic deposit in Dongyangquan area are summarized by combing the previous regional geological data and the investigation results of strata,structure,magmatic rocks and geochemistry.The results show that the exposed Cambrian strata are favorable ore-bearing strata for the middle-low temperature hydrothermal minerals,and the fault structure mainly develops in the north west direction.The anomaly scale of silver,lead,gold and other elements is large,and the anomaly integration is good.The Yanshanian magmatic activity provided the source,heat and power for the migration of beneficial elements.The Dongyangquan area has a very similar metallogenic environment to Longbaoshan gold deposit,with good ore-forming material sources,activation,migration and enrichment conditions,and good prospecting prospects for medium-low temperature hydrothermal gold and metal deposits.
