| 摘 要： | 介绍了正常海相硅质细碎屑沉积物有机碳与硫化物硫比值（C／S）的含义。以秦岭镇旬盆地南羊山组不同沉积环境沉积物C／S值为例，讨论了还原环境中活性铁的不足对沉积物C／S值的影响，以及有深部成矿物质参与的沉积物具后期发生流化物化沉积物特征的可能性。

| Abstract: | The meaning of organic carban and sulfide sulfur ratios (C／S) in nnrmal marine silicate fine-grained sedi-ments is briefly introduced .Taking the ratios in different environment sediments of the Nanyangshan Formation in the Zhenxun Basin ,Qinling for example ,the effects of deficiency of active iron on the C／S ratios of sediments in the reducing environment ,as well as the possibility that the sediments with deep-source ore-form- ing materials involved are characteristic of epigenetic sulfidation are discussed . |
