摘要
通过对中国典型的淡水湖相(茂名)和盐水湖相沉积环境(江汉)岩样的生物标志化合物单体碳同位素数据的分析,探讨了产生两环境化合物的来源和沉积环境.研究发现茂名油页岩中姥鲛烷和植烧来源于叶绿素α的植基侧链,含量高的4-甲基甾烷通过与藿烷和甾烷的同位素对比,推测其源与细菌有关.江汉油页岩中的化合物明显不同于茂名油页岩,伽马蜡烷(Gammacerane)来源于喜盐的原生生物,δ13C值为-25‰左右,与报道的值一致.植烷和姥鲛烷与来源于浮游植物的甾烷及4-甲基甾烷接近,说明其三者均来源于浮游藻类.报道了卟啉化合物的GC-IRMS碳同位素测定方法及中国样品中的卟啉碳同位素值.江汉盆地的DPEP,etio δ13C值相似,来自于叶绿素.而茂名油页岩中etio和C31DPEP较C32DPEP轻,说明C32DPEP来源于叶绿素a,而etio和C31DPEP有别的来源.
