| description | Major and trace element compositions of lignite from the Tertiary Ogwashi-Asaba formation, Southern Nigeria, have been investigated to determine the prevailing environmental conditions which controlledtheir formation. Seven samples were obtained from outcrops along river valleys, streams and springs in seven localities; these samples were subsequently analysed using fusion combined with inductively-coupledplasma (FUS-ICP) and total digestion with inductively-coupled plasma (TD-ICP). Geochemical analysis revealed the following concentration range in weight percent (wt. %) for major oxides: SiO2 (0.04-9.78);Al2O3 (0.56-6.40), Fe2O3 (0.05-1.22), MnO (0.001-0.004), MgO (0.02-0.11), CaO (0.05-0.15), K2O (0.01 - 0.04), TiO2 (0.016-0.299) and S (0.08-0.39). Trace elements indicated the following concentrationrange in parts per million (ppm): Be (2-5), Zr (4-63), Sr (5-22), Y (13-68), Ba (9-89), V (4-216), Zn (17- 176), Ni (8-28), Co (5-13), Cr (2-31), Cu (1-22) and Ga (1-14).
