A geogas prospecting technology suitable for the exploration of concealed sandstone-type uranium deposits in desert areas
摘要
Abstract
This study developed a geogas prospecting technology suitable for concealed sandstone-type uranium deposits in desert areas.This prospecting technology consisted primarily of three parts:A geogas information collection device and sampling method tailored to desert,a method for geogas information preprocessing using the detector and material composition tests,and a method for data process-ing and anomaly inference and interpretation.This technology was developed based on the mechanisms behind geogas material migration and utilized a desert-specific,dust pollution-resistant geogas material sampling device equipped with a detector made of low-background polyurethane foam.Through cumulative sampling for around 45 d,this technology can effectively capture the content of U,rare earths,and associated(paragenetic)elements in concealed sandstone-type uranium deposits within desert-covered exploration areas and delin-eate deep uranium enrichment zones,thus achieving the goal of ore prospecting.The world's first geogas exploration section for sand-stone-type uranium deposits in a desert area has been completed in an exploration area in Xinjiang,demonstrating the effectiveness of the geogas prospecting technology developed in this study.关键词
