辽东地区前寒武纪地层分布很广,出露面积约占总面积的70%。与老地层有关的矿产资源比较丰富,铀矿和老地层的关系特别与混合岩化作用更为密切。作者于1960年初在本溪沈家堡子填图时,将原弓长岭花岗岩(对面山花岗岩)改定为混合岩,1972年发现,每次造山运动后的沉积间断面控制着铀和钍的集中和矿化。元古界底部不整合面的确定,以及元古界
Precambrian strata in the Liaodong area are widely distributed, exposing an area of about 70% of the total area. The mineral resources related to the old formation are relatively abundant, and the relationship between uranium deposits and the old formation is particularly close to that of the mixed rock formation. When the author mapped the original Gongchangling granite (opposite granite) into a mixed rock during the mapping of the Shenjiapuzi in Benxi in early 1960, it was found in 1972 that the sedimentary facies after each orogeny controlled the concentration of uranium and thorium Mineralization. The determination of the unconformity at the bottom of the Proterozoic, and the Proterozoic
