通过系统研究,将沉积环境有机质分为可确定或未确定的高相对分子质量有机物质、简单物质和腐殖质3个主要部分,一般称为非腐殖质和腐殖质2个部分.非腐殖质系指那些可被列入单独的化合物类别中的有机化合物,主要包括糖、脂类和氨基酸；腐殖质系指那些很难确定的不能再分成其他化合物的有机化合物,据其溶解性质和颜色特征,腐殖质分为黄腐酸、腐殖酸和腐黑物3个部分.通过氯仿提取实验和腐殖质提取实验,证实了有机质特别是腐殖质中的黄腐酸在铀矿成矿过程中起着主要作用.%Systematic research on organic matter in the sedimentary environment reveals three organic matters, I. E high molecular weight organic matter, simple organic matter and humus. Generally they are called humus and non-humus. Non-humus (Nonhumic substances) are those that can be included in a separate category of organic compounds including mainly sugar, lipids and amino acids. Humus (Humic substances) are those that are difficult to identify and can not be classified into other organic compounds and according to their solubility and color they are divided into, humic acids, and black rot complex (Humin) and chloroform extraction and humus extraction experiments show that organic matter, especially for ful-vic acid plays an important role in formatin of uranium ore.
