摘要
本文详细研究了四川中梁山、南桐矿区晚二叠世龙潭组煤中硫的赋存状态,发现煤中存在黄铁矿化的动物、植物遗体,尤其存在大量硫细菌和硫酸盐还原菌化石。通过煤岩学及沉积学研究,探讨了聚煤环境对煤中黄铁矿形成的控制作用。通过对煤中植物残体的扫描电镜-能谱检测,发现不同成煤植物有机硫含量不同,辉木类硫高,石松类硫较低,在各组显微组分中镜质体有机硫含量高于丝质体。
In a detailed investigation of occurrence of sulphur in coal of Late Permian Longtan Formation from Zhongliangshan and Nantong coal fields in Sichuan province,pyritized animal and plant remains were found in coal,especially a lot of sulfur bacteria and sulphate reducing bacteria fossils. Based on coal petrology and sedimentology,the controlling effects of coal accumulating environment of pyrite formation in coal are discussed in this paper. Observations of plant remains in coal by SEM-EDAX have revealed that the organic sulfur contents vary with different coal-forming plants,for example,organic sulfur in Psaronius is high and that in Lepidophyta is low. In addition,the organic sulfur in vitrinite is higher than that in fusinite.
