龙胜古生界地球化学特征

GEOCHEMICAL CHARACTERISTICS OF PALAEOZOIC ERATHEM IN LONGSHENG COUNTY

文章运用正态检验估计法确定地层元素含量背景值。结果表明，龙胜地区古生界在沉积成岩过程中，砂质岩和碳酸盐岩大多数元素的原始富集程度较高，而泥质岩多数元素的原始富集程度较低。整个岩系多数元素的后期叠加作用不明显。

This paper uses normal test-estimate method to ascertain the background value of elements' content in strata. The consequence makes known, in the diagenetic process of sedimentation, that the primary concentration degrees of most elements in sandy rock and carbonate rock were fairly high, but those in argillaceous rock were lower. The late superpositions of most elements in the whole rock series weren't obvious.
