摘要
元素地球化学研究表明:广西龙胜地区上元古界浅变质含砾砂岩、细砂岩、粉砂岩及大理岩的成矿元素丰度普遍较高,具有显著浓集和后期叠加作用;含砾板岩、板岩、千枚岩及硅质岩的元素丰度较低。
Study of element geochemistry shows that the Late proterozoic light metamorphic gravel bearing sandston, fine sandstone, siltstone and marble in Longsheng area, Guangxi, are commonly higher in element abundance, indicating obvious concentration and later superposition;gravel bearing slate, slate phyllite and siliceous rock are lower in element abundance, implying no obvious concentration and later superimposition.
