黑色页岩中硫的存在状态较为复杂 ,包括有机硫、黄铁矿和硫酸盐等不同形式 .含硫矿物的结构、各种形态硫的含量和同位素特征与黑色页岩形成环境及成岩变化有密切关系 .通过对湘西黑色页岩中多种形态硫的定量分析和同位素测定 ,讨论了湘西晚震旦世 早寒武世黑色页岩硫的分布和形成条件 .
The existing state of sulfur in black shale is more complicated, including different forms of organic sulfur, pyrite and sulphate, etc. The structure of sulfurous minerals, the contents and isotopic characteristics of various forms of sulfur, the formation environment of black shale and the diagenetic changes The relationship between the distribution and the formation of sulfur in the black shale of Late Cambrian in the Late Sinian in western Hunan was discussed through the quantitative analysis and isotopic measurements of various forms of sulfur in the black shale of western Hunan.
