摘要
Abstract
Erlian basin is an important Mesozoic-Cenozoic uranium-bearing basin in northern China,and significant exploration progress has been achieved in recent years.This study focuses on the Manglai-Bayanwula-Naren study area by systematically collecting and organizing geological,drilling,geophysical,and remote sensing data.SKUA-GOCAD three-dimensional modeling software was used to construct a three-dimensional geological model of boreholes,strata,and ore bodies.By analyzing the geological background,geological characteristics,mineralization patterns,a geological exploration model was established first.Subsequently,quantitative extraction of geological anomaly information was carried out to set a three-dimensional spatial model for the metallogeinic prediction.The"cube prediction model"was employed for the three-dimensional quantitative prediction by using a comprehensive delimitation method that combines the three-dimensional information method and the weights-of-evidence method.Finally,seven metallogenic potential areas were delineated with total estimated resource of over 58,000 tons.The study not only points out the uranium exploration directions in the peripheral and deep parts of the existing mining areas,but also consolidate the uranium resource reserves.关键词
