Okeke, Adaobi Isabella, Anike, Luke Okechukwu, Ezeh, Hilary & Okoyeh, Elizabeth Ifeyinwa · Asian Journal of Geological Research · 2019

The Ishiagu galena - sphalerite vein mineralization was investigated for its stable isotope composition to determine the characteristics and source of the mineralizing fluid. The δ34S of galena, sphalerite and chalcopyrite range from -5.00/00 to -8.00/00, -2.00/00 to -4.90/00 and...

Establishing the Conditions of Formation of Ishiagu Galena-Sphalerite Mineralisation, Southeastern Nigeria Using Stable Isotope

Okeke, Adaobi Isabella, Anike, Luke Okechukwu, Ezeh, Hilary & Okoyeh, Elizabeth Ifeyinwa · Journal of Scientific Research and Reports · 2018

The study area is located at southwestern extreme of the Benue Trough of Nigeria. The area is bounded by latitude N50 57’0’’ - N50 54’0’’ and longitude E70 32’ 0’’- N50 54’0’’. The Ishiagu galena-sphalerite deposit occurs in the Cretaceous (Albian) carbonaceous shale intruded by...
