英文摘要	Distinctive land plant biomarker distributions have been described for Triassic-Jurassic source rocks in the Dampier sub-Basin, Northwest Shelf of Australia. Proxies like the higher plant parameter [HPP = retene/(cadalene + retene)] cannot be applied to describe palaeoclimate globally; in fact, the HPP showed similar values (similar to 0.8) for Triassic and Jurassic source rocks despite the difference in sea level. The higher plant fingerprint [HPF or relative distribution of retene, cadalene and 6-isopropyl-1-isohexyl-2-methylnaphthalene (ip-iHMN)], however, represents a potential discrimination tool for source rock intervals. Here, we name this proxy as plant fingerprint (PF) since our investigation supports a non-vascular plant origin for ip-iHMN. The most distinctive patterns in the PF are found in the Early Jurassic with a predominance of cadalene (similar to 65%) in an arid climate, and the Middle Jurassic with a predominance of retene (similar to 70%) during a climate recovery under more humid conditions. Petroleum fluids from the Dampier sub-Basin are cadalene-dominated compared to fluids from the Barrow sub-Basin, which are retene-dominated. We emphasise that the present approach has only local implications and the parameters used herein (including the higher plant parameter or HPP) cannot lead to interpretations at a global scale.
