摘要
通过对目的层层间氧化分带岩石学、地球化学指标、常量元素及其变化规律的分析,初步研究了准噶尔盆地东部将军庙地区砂岩型铀矿的地质地球化学特征。研究认为:(1)将军庙地区的层间氧化带可分为强氧化亚带、弱氧化亚带、过渡带和原生还原带;(2)研究区氧化作用存在长时期间断,造成过渡带铀富集较弱,矿带范围较局限;(3)SiO2、MgO和TiO2与铀元素的富集具一定相关性。
Based on the analysis of petrology,geochemical indicators,macroelements and their changing laws of the alteration zones of the ore-bearing target layer,this paper comprehensively studies the geological and geochemical characteristics of sandstone-type uranium deposits in the Jiang Junmiao area,the eastern Junggar Basin.According to the research,the post-alteration alteration in the study area can be divided into strong oxidation sub-band,weak oxidation subband,reduction zone and transition zone;the inter-oxidation failed to develop continuously,which is the reason for the low grade of ore-bearing sandstone;the enrichment of SiO2,,MgO and Ti O2 in the study area has a certain concomitant relationship with uranium.
