The abundance of hopanes, homohopanes (C31-C35), benzohopanes and C29 steranes and diasteranes in most of the samples indicate terrestrial plant, phytoplankton and cyanobacteria contributions to the organic matter that formed the coal. High (Pr/Ph) ratio (1.73-12.47 indicates Mamu samples consisted of terrestrial organic matter with marine incursion deposited under oxic/suboxic-oxic in lacustrine-fluvial/deltaic environment. The distribution patterns of C32-C35 benzohopanes in Mamu samples confirmed the redox condition of organic matter deposition within the Formation. The presence of unsaturated oleanenes in Mamu samples further confirmed their thermal immaturity status. The kerogen types of the samples have capacity to generate both oil and gas. Benzohopanes (C32-C35) and three oleanene isomers; olean-12-ene, olean-13 (18)-ene and olean-18-ene were present in samples collected from Mamu Formation. Coals from Mamu Formation have potential to generate both oil and gas but are presently immature to have formed any significant hydrocarbons.
