几年来,径迹蚀刻测量在攻深找盲和扩大老矿区的工作中已取得了较好的经济效益。我队在砂砾岩地区利用径迹测量预测远景地段也取得了较满意的效果。 1.测区的地质概况 测区岩性为第三系红色砂砾岩,东侧为燕山期花岗岩,二者呈断层接触或沉积接触。盆地基底为花岗岩,铀矿化赋存于基底花岗岩内。其盖层为红色粘土质砂砾岩,它可以作为早期矿化的盖层,有利于矿化的保存,其厚度由一百米到几百米不等。砂
In recent years, track etch measurements have achieved good economic benefits in tapping the blind and expanding the old mining area. Our team also made satisfactory results in the prediction of long-term locations in the glutenite area by using track measurements. 1. Geological Survey Area The lithology in the survey area is red sand conglomerate of Tertiary, Yanshanian granite on the east side, and the two are in fault contact or sedimentary contact. The basement of the basin is granite, and uranium mineralization occurs in the basement granite. Its cover is red clay conglomerate, which can be used as an early mineralized cap layer, is conducive to the preservation of mineralization, and its thickness from a hundred meters to several hundred meters. sand
