土壤氢测量方法在砂岩型铀矿勘查中的试验研究
Experimental Research on Soil Hydrogen Measurement Methods for Exploration of Sandstone-type Uranium Deposit
摘要
Abstract
Based on the relationship and migration mechanism between soil hydrogen concentration and uranium mineralization,this paper presented an experimental study using a portable gas chromatographic hydrogen analyzer at Barun uranium deposit in Erlian Basin and Tamusu uranium deposit in Bayingobi Basin.Verification applications were also conducted in Tumen uranium exploration area of Erlian Basin.A preliminary methodology and workflow for field data collection,data processing,and the determination of the lower anomaly limit for uranium exploration using soil hydrogen was established.The distribution characteristics and variation patterns of soil hydrogen concentration in different geological zones,including barren,anomalies,mineralization and orebodies,and fault structures were summarized.Furthermore,the mineral-induced anomalies and fault anomalies caused by soil hydrogen concentration,as well as the fault characteristics in mineralized and barren area were summarized.The mechanism of soil survey methods for sandstone-type uranium deposit exploration was discussed,along with the relationship between soil hydrogen concentration anomalies and uranium ore bodies and faults,as well as the migration patterns,advantages,applicable conditions,and influencing factors of soil hydrogen.A soil hydrogen exploration model for sandstone-type uranium deposits was established.The research results indicate that the soil hydrogen method for exploring sandstone-type uranium deposits is feasible and effective,aligning with the current understanding of soil hydrogen migration mechanisms and their correspondence with uranium ore bodies.The hydrogen measurement method can quickly and effectively delineate the planar locations of uranium ore bodies,mineralization,anomalies,and fault structures,which will be effective and novel approach in the exploration of sandstone-type uranium deposits and has significant application prospects.关键词
