| 摘 要： | 陕西马元铅锌矿石的显著特征之一是富含有机质。除了肉眼和显微镜下能够识别的沥青外,还有丰富的呈分散状的有机质,要通过有机化学分析来确定其成分。笔者试图通过岩矿石光薄片显微鉴定、有机质含量、有机质碳同位素、饱和烃气相色谱等的测试分析,了解有机质在岩矿石中的赋存状态、有机质组成,认为沥青成因类型属于同生-成岩沥青、后生(改造)沥青及表生沥青;并根据正构烷烃、姥鲛烷、植烷等生物标志物,判别有机质母源,分析成矿环境,认为有机质与铅锌成矿有一定的关系。

| Abstract: | The existence of rich organic matter constitutes one of the notable features of the Mayuan lead-zinc deposit in Shaanxi Province.In addition to the asphalt that can be identified by naked eyes and microscope,there occurs extremely abundant scattered organic matter whose composition needs to be analyzed by means of organic chemistry.Based on a microsection identification of rocks and minerals,an analysis of content and isotopes of the organic matter,and chromatography of saturated hydrocarbon gas,the author ... |
