摘　　要：研究区位于豫西多金属成矿带,区内发育多处水系沉积物地球化学异常及航磁异常,成矿背景良好。通过1:1万土壤地球化学剖面测量、岩石元素地球化学测量及野外查证,查明该区土壤、岩石元素地球化学背景特征及两者之间的联系,研究成矿元素趋势特征和地球化学异常成因,对1∶20万水系沉积物地球化学异常进行分析与评价,为该区进一步开展矿产评价工作提供可靠依据。The study area is located in Western Henan polymetallic metallogenic belt with good metallogenic back-ground,and several stream sediment geochemical and aeromagnetic anomalies are developed in this area.Through 1:10000 soil geochemical profile survey,and rock element geochemical survey with field verification,the geochemical back-ground characteristics and relationship of soil and rock element were identified,and the trend characteristics of ore-forming elements and the cause of geochemical anomalies were studied.On this basis,the geochemical anomalies of 1:200000 stream sediments were analyzed and evaluated,so as to provide a reliable basis for further mineral evaluation in this area.
