摘　　要：河南栾川钼钨铅锌银多金属矿集区位于东秦岭地区多金属成矿带,区内中生代岩浆活动剧烈,是我国重要的钼多金属矿集区。以河南栾川矿集区为研究区,以成矿系统和地质异常理论为指导,根据矿集区内典型钼钨铅锌银多金属矿床成矿模式和3D建模流程,利用矿集区的矿产勘查大数据和智能矿山/矿业大数据等资料,对地质-地球物理剖面进行2D/2.5D重磁交互反演,建立三维地质-地球物理找矿地质与勘查模型;在此基础上,结合构造地球化学,深层次挖掘三维勘探变量,优选了重磁三维勘探模型和构造地球化学勘探变量模型,准确快速地建立综合找矿模型和圈定深部靶区。The Luanchuan molybdenum tungsten lead zinc silver polymetallic ore concentration area in Henan Province is located in the East Qinling polymetallic mineralization belt.The Mesozoic magmatic activity in the area is intense.It is an important molybdenum polymetallic deposit area in China.Taking Luanchuan ore concentration area in Henan Province as the study area,guided by metallogenic system and geological anomaly theory,based on the typical mineralization mode and 3D modeling process of molybdenum tungsten lead zinc silver polymetallic deposits in ore concentration area,using mineral exploration big data and intelligent mining/mining big data in ore concentration area,2D/2.5D gravity magnetic interaction inversion was conducted on the geological geophysical profile to establish a 3D geological geophysical prospecting geological and exploration model.On this basis,combined with structural geochemistry,3D exploration variables were deeply excavated,and the gravity and magnetic 3D exploration models and structural geochemical exploration variable models were selected to accurately and quickly establish a comprehensive prospecting model and delineate deep target areas.
