格陵兰东北霍克斯特郎半岛地区的富树脂、高硫煤是优质的油源岩。I_H可能超过了700,其总生烃潜力估计为27×10~6bbl/km~2。这种低阶煤还没有完成生烃潜力,其整体上以壳质组显微组分为主,其中树脂为最主要的组份,占煤的70%。抽提饱和烃组分的生标分布显示出一系列特征,包括高含量的倍半萜和二萜、高Pr/Ph比值、低CPI、烷基和甲基烷基环己烷优势、低含量的三环三萜和藿烷及明显的C_(29)比C_(27)甾烷优势。泥炭沉积于静水近海岸环境,以少量的碎屑物注入和偶尔的海侵为特征,母质植物以未知的裸子植物为主。
The resin-rich, high-sulfur coal in the Hawkeshire Peninsula in northeastern Greenland is a good source rock. I_H may exceed 700, and its total hydrocarbon generation potential is estimated at 27 × 10 ~ 6bbl / km ~ 2. The low-rank coal has not yet completed hydrocarbon generation potential, and the whole is dominated by chitin microstructures, of which resin is the most important component accounting for 70% of the coal. The biomarker extraction of the saturated hydrocarbon components shows a series of characteristics including high content of sesquiterpenes and diterpenes, high Pr / Ph ratio, low CPI, advantages of alkyl and methyl alkylcyclohexanes, low content of Of tricyclic triterpenes and hopanes and obvious C_ (29) C_ (27) steranes. Peat sediments are deposited in the hydrostatic offshore environment, characterized by small debris influxes and occasional transgressions, with the parent plant being dominated by unknown gymnosperms.
