Composition, Classification And Quality Of Lignite In Nnewi And Environs, Niger Delta Basin, Nigeria

Abstract X-ray diffraction (XRD) analysis and x-ray fluorescence stereoscopy (XRF) have been carried out on eleven (11) lignite samples from the Ogwashi-Asaba Formation. Results of X-ray diffraction analysis suggest the lignite samples are composed of some impurities which include the clay mineral kaolinite and non-clay minerals such as quartz, pyrite, cristabolite and graphite. X-ray fluorescence...

ABSTRACT The rhythmic thickness variations in the Nanka Formation exposed in a roadcut at Umunnya were measured and analyzed to confirm (i) that the rocks were deposited under strong tidal influence, and (ii) to determine the specific tidal system that prevailed at the time of sedimentation. Facies analysis reveals three lithologic intervals: sandy, claystone and...

ABSTRACT The textural characteristics of the of the Oweli Sandstone are evaluated to reveal the depositional processes A total of 400 pebbles and twenty sandstone samples were systematically collected from two horizons along the outcrop belt in the study area were subjected to pebble morphometric and sand-size particle analyses. Results of the pebble analysis show...

ABSTRACT Geochemical analysis of water samples collected from Mbieri and environs in Imo State of Nigeria, was conducted to evaluate the levels of physical and chemical contamination and their impacts on public health. The results reveal that the pH of the water samples analysed are all within the World Health Organisation permissible limits (ranged between...

X-ray fluorescence analysis of the sandstone component of the Nsukka Formation in the Inyi-Okigwe area of the Anambra Basin, was conducted to determine the mineralogical composition and interpret the depositional history. The results revealed that the sandstone has an average silica (SiO2), alumina (Al2O3), and iron oxide (Fe203) contents of 93.89%, 1.91%, and 1.28% respectively....
