This research investigates the distribution of n-alkanes (m/z 85), Steranes (m/z 218) and hopanes (m/z 191) in Chikila, Lamja, Lafia Obi, Maiganga and Okaba coals from Northern Nigeria in order to assess their source organic matter, depositional environment and thermal maturity using GC-MS. The results revealed that the source organic matter of the coals is terrestrial higher plants while the depositional environment is terrestrial under oxic condition. The coals have the potential to generate oil but are not yet thermally matured.
