An oil shale deposit, possibly of high economic value and corresponding to the Turonian Ezeaku shale (lower Nkalagu formation) of the Lower Benue Trough, was found in a 1.5 × 1.0 km belt in Lokpanta near Okigwe, in Imo State, Nigeria. The characteri

The variation of the absolute concentration of oleananes in three selevted sedimentary columns of the Tertiary Niger delta is paralleled by the corresponding oleanane parameter (OP) profile, thereby confirming that the latter can be utilized for esti

Asphaltenes from the Athabasca and Nigerian tar sands were chemically degraded by reducing metal reaction to yield, in each case, non-asphaltenes material (“maltene-I”) that afforded a homologous series of long-chain n -paraffins maximizing at n

The major steranes of the non-asphaltene fraction of Nigerian tar sand bitumen (maltene) are the c27-c29 diasteranes [13β(H),17α(H); 20R + S] and C28-C29 regular steranes [14β (H),17β (H); 20S]. The reducing metal reaction products of the corresp

Oleananes occur within well-defined age and paleogeographic boundaries in the sedimentary province of Southern Nigeria thus signifying that the biomarkers may be analogous to Index Fossils. In Anambra Syncline/Lower Benue Trough the biomarkers are fo
