Leaves in turbidite sands: The main source of oil and gas in the deep-water Kutei Basin,Indonesia:Discussion
Sailer et al. (2006) have concluded that leaves in the upper Miocene turbidite sands were the main source of oil and gas in the deep-water Kutei Basin, East Kalimantan (Borneo), Indonesia. They have reported that oils from the Kutei Basin have high (4-7) pristane/phytane ratios, suggesting a coaly organic source. This is consistent with other observations made on oils from the Gippsland Basin in Australia, showing high pristane/ phytane ratios (5-6) that were attributed to coniferous rain forests and related land-plant organic matter (Shanmugam, 1985).
