达到了1.3%,而它的含硫多环芳烃的含量低于50t培∥gC鸭.实验证明,取自Sieroszowiee―l,Si. eroszowice一2,Polkowice一1和Konrad地区的样品中的含硫多环芳烃含量较高(450ttg/gC哪一 85099/sC哪),它们的成熟度介于O.7%一O.9%民,贱金属含量低于5%.形成于静海相环境下 的高矿化度样品的贱金属含量达到23.1%,而舍硫多环芳烃的含量仅为52倒gC哪,这是因为在 沉积的过程中,硫优先与贱金属反应,只有当金属被消耗完时,硫才会与有机质反应形成含硫的 多环芳烃.所以沉积环境、干酪根类型和含硫多环芳烃在地层中的迁移不是含铜页岩中含硫多 环芳烃形成的主要因素. 关键词:舍硫多环芳烃;

50 (tc/g C啷.Higher PASC contents(450~850(t^g/g Corg)are observed in the samples of SCl,SC2,PKl and the samples from Konrad section.Their Ro values are between 0.7 and O.9%.and their base metal contents黜lower than 5%.In a highly mineralized sample with base metal content of 23.1%.the PASC content is only 52(倒g C哪.This phenomenon may be explained by the preferential reaction of sulfur with base metals during the depositional process.Only after metals are used up.sulfur would react with organic matter and form PASCs.The depositional environment,kerogen type and the migration of PASCs from oth- er strata are apparendy not the predominant factors for the formation of PASCs in the Kupferschiefer.
