A characteristic feature of Cenoman- ian–Turonian age oils from the Canadian Arctic is a relatively high abundance of C28 regular steranes, compared to C27 and C29 regular steranes, whereas Upper Jurassic oils generally show a rather low abundance of C28 regular steranes.	cache/geusb-4783.pdf	txt/geusb-4783.txt
