准噶尔盆地铀矿地质工作回顾及今后找矿方向

摘要

准噶尔盆地自1955年开始进行铀矿地质勘查及评价工作,60年来共完成钻探工作量超过26×104 m,已经发现铀矿床1处,矿点10余处。近年来,在地浸砂岩型铀矿找矿方面虽取得了大量成果,但由于对这些成果缺乏系统的梳理并受一些因素的影响,该区的找矿工作还难于深入推进。笔者试图通过对前人在该盆地的铀矿地质工作进行全面总结,在明确已经取得的主要成果认识基础上,从中发现可能被疏忽的主要地质问题,并提出今后的找矿方向,为该盆地砂岩型铀矿找矿工作取得新突破提供参考依据。%Uranium exploration and resource evaluation in Jungar basin was began in 1 955,and over 26 ×10 4 m drilling efforts was finished in the past 60 years and one uranium deposit and more than 10 oc-currences were discovered up to now.In recent years,great achievements was made in the exploration of leachable sandstone type uranium deposit,but break through efforts was not yet preformed due to the restricting factors and the lack of systematic and comprehensive clear up of the achievement.This paper is try to make an overall summary of the finished efforts and find out the question which was passed into si-lence on the basis of ascertaining the achievement so as to put forward the orientation for the future ex-ploration and provide reference evidence for the break through of prospecting of sandstone type uranium deposit in the basin.
