Three varieties of gypsum deposits occur in numerous locations within the Senonian Fika Shale in Nafada area, northeastern Nigeria. Geological investigations at Gonja, Warum, Ganko, Shole, Sudingo, Gadi, Mada and Papa mines show the occurrence of the three varieties namely: Satinspar, Selenite and Alabaster. These gypsum deposits occur within the gypsiferous Fika Shale with thicknesses within the span of 1 to 6 cm and depth of 0.2 to 15 meters. The gypsum are hosted within veins sometimes criss - crossing in some locations, pores and fractures inter layered within the fissile Fika Shale intercalated with mud. Analyses of seventeen fresh gypsum samples by X-ray spectrophotometer technique indicate mean average compositions of 93.06,92.59 and 93.60 wt % of CaSO4.2H2O; 2.04, 2.32 and 1.80 wt % SiO2; 0.38, 0.40, and 0.70 wt % of Fe2O3+AL2O3; 0.36, 0.34 and 0.11 wt % of MgO; 0.13, 0.14 and 0.13 wt of Alkalis (Na2O +K2O) and purity of 96.43, 96.48 and 96.42 for Satinspar, Selenite and Alabaster respectively. These chemical data indicate high grade of gypsum which may be suitable in: cement, ammonium sulphate fertilizer, pharmaceutical, ceramics/pottery, cosmetics, soil amendment, building, chemical, paints and textile industries.

“…This same transgression resulted in the deposition of Dukul, Jessu and Sekuliye Formation and the Numanha shales in the Yola arm of the Northern Benue Trough. The lithology of all the marine sediments are characteristically similar consisting of sequences of shales, limestones, mudstones with few horizons of calcareous sandstones, siltstones and sandstone (Carter et al, 1963;Avbovbo et al, 1986;Zaborski et al, 1997;Ntekim, 1999).…”

Lithological mapping of the Dumne area revealed that the area is underlain by rocks that constitute members of the Basement Complex represented by migmatite-gneiss, porphyritic granite, coarse-grained granite, dolerite and pegmatite. The Cretaceous sedimentary rock is examplified by sandstone of Bima Formation and the Tertiary/Quaternary extrusives is typified by basalt. Structurally controlled, epigenetic fracture-filling, vein-type baryte-fluorite mineralization occurs in three locations of the Dumne area. The baryte-fluorite veins are hosted within fractures and fault zones in the migmatite-gneiss and porphyrytic granite. Thin-section investigation indicates that the migmatite-gneiss, porphyritic and coarse-grained granite are mineralogically similar having essential minerals consisting of quartz, orthoclase, biotite, plagioclase, hornblende and microcline with variable accessory minerals such as zircon, apatite, sericite, sphene and iron oxide. Dolerite and basalt have identical mineralogical composition characterized by presence of pyroxene, olivine, plagioclase, biotite and iron oxide while pegmatite has quartz, orthoclase, plagioclase and muscovite as its mineralogical composition. Bima sandstone is typified by presence of quartz, orthoclase, zircon and limonite. This study has succeeded in revealing the mineralogical and composition of the rocks in Dumne area and has outline baryte-fluorite mineralization as the main mineral of interest which is economically viable.
