The Puzhengou lead-zinc deposit in this region is a hydrothermal type deposit, which is the first lead-zinc deposit discovered on the western margin of the Puzhengou rock mass. This lead-zinc deposit is expected to reach a medium scale, and associated element indium reaches a large scale. The application of multidisciplinary and multi-mean comprehensive prospecting methods can effectively improve the accuracy of geological, geophysical, and geochemical anomaly interpretation. Taking the Puzhengou lead-zinc polymetallic deposit as an example, this work utilized comprehensive geological-geophysical-geochemical information, and first established a prospecting model for hydrothermal vein type lead-zinc polymetallic deposits (associated with rare elements such as indium, thallium, cadmium, etc.) in the east Qinling metallogenic belt. We also summarized the exploration workflow, in an attempt to provide reference and guidance for searching for similar lead-zinc polymetallic deposits in this region. The geochemical characteristics of the deposit are mainly element combination anomalies of lead, zinc and silver, accompanied by anomalies of gold, tungsten, arsenic and molybdenum. The geophysical characteristics of the deposit are weakly polarized and low-to-medium resistivity-dominated IP anomalies. The selection of exploration workflow and method is as follows: first of all, the 1∶200, 000 and 1∶50, 000 stream sediments in the study area were comprehensively studied, in order to narrow the scope of key prospecting targets. Secondly, we selected a combination of soil geochemical exploration and induced polarization gradient profile to verify stream sediment anomalies and further narrow the scope of key target areas. Subsequently, an integrated geological-geochemical method combining rock geochemical profiles and trench sampling was implemented to determine the genesis of soil anomalies and evaluate the mineralization potential within surface fault-related alteration zones. Finally, a geological-geophysical prospecting approach incorporating high-power time-domain induced polarization sounding and drilling was deployed to delineate and confirm the extension of ore bodies at depth., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=20250209.pdf, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=null, pdfFileSize=null, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, fund=null), CN=ArticleExt(id=1256260907630510664, articleId=1256260907043308095, tenantId=1146029695717560320, journalId=1256213323050663944, language=CN, title=豫西蒲阵沟热液脉型铅锌多金属矿地球物理、地球化学异常特征及找矿模型, columnId=1256260903973077550, journalTitle=地质与勘探, columnName=矿产地质, runingTitle=null, highlight=null, articleAbstract=豫西崤山地区是我国重要的金、银、钼、铜、铅锌多金属成矿区，区内蒲阵沟铅锌矿为热液型矿床，是蒲阵沟岩体西缘发现的首个铅锌多金属矿床，伴生稀散元素铟金属量达到大型规模，铅锌矿规模有望达到中型。多学科、多手段综合找矿方法的应用，能有效提高地质、地球物理、地球化学综合异常解释的准确性。本文以豫西蒲阵沟铅锌多金属矿为例，在综合运用地质、地球物理、地球化学等多种勘查手段的基础上，首次建立了东秦岭成矿带热液脉型铅锌多金属矿 （伴生铟、铊、镉等稀散元素） 的综合信息找矿模型，并总结了勘查工作流程，以期为区域上寻找同类型铅锌多金属矿床提供参考和依据。该矿床的地球化学特征是以铅、锌、银为主的元素组合异常，伴生有金、钨、砷、钼等元素异常；地球物理特征以弱极化、低-中电阻率为主的激电异常特征。勘查工作流程及方法选择具体如下：首先，综合研究区域1∶200, 000、1∶50, 000水系沉积物测量的各类异常，筛选重点找矿靶区。其次，选择土壤化探扫面+激电中梯剖面扫面的地球物理-地球化学找矿方法组合，对水系沉积物异常进行查证，逐步缩小重点靶区的范围；再次，选择岩石化探剖面+槽探的地质-地球化学探测方法组合，基本查明土壤异常产生的原因以及地表断裂构造蚀变带的含矿性；最后，利用大功率时间域激电测深+钻探的地质-地球物理找矿方法组合，查明并验证矿体深部的延伸情况。, authors=吴 煜1,2 , 豆贯铭1,2 , 许保国3 , 岳 涛1,2 , 王建统1,2 , 李新萍1,2 , authorsList=吴煜, 豆贯铭, 许保国, 岳涛, 王建统, 李新萍, authorCompany=1 河南省第一地质矿产调查院有限公司，河南洛阳 471000;
