This paper investigates the removal of chromium III from aqueous solutions by adsorption process using abundant vesicular basalt available around Abbay River in Ethiopia The batch adsorption method has been employed to evaluate the effect of various experimental parameters pH ionic strength initial concentration and contact time on Cr
Res 98 1993 15803] and in one Oligocene basalt from the Ethiopian Plateau [Geochim Cosmochim Acta 63 1999 2263] Trace element Sr and Nd isotope systematics suggest the involvement of a discrete but minor LREE depleted component in the genesis of these basalts The latter is not depleted MORB mantle but is possibly an intrinsic part of
The Axum volcanic rocks constitute an important outcrop of trap basalts at the northern end of the great Ethiopian flood basalt province They constitute about 5 480 m thick sequences exposed around Axum and Shire regions covering a total area of about 900 km though the Axum volcanic rocks were previously assigned to the low Ti LT tholeiitic
The Ethiopian plateau is made up of several distinct volcanic centres of different ages and magmatic affinities In the NE a thick sequence of 30 Ma flood basalts is overlain by the 30 Ma Simien shield volcano The flood basalts and most of this shield volcano except for a thin veneer of alkali basalt are tholeiitic In the centre of the province a far thinner

et al 1999; Ukstins et al 2002 These are part of the larger Ethiopia/Yemen Igneous Province which is related to the Afar plume and the Red Sea Gulf of Aden Ethiopia triple junction Flood Basalt magmatism resulted in a basaltic lava pile of more than 2 000 m thick with an estimated volume of 106 km3 Rochette et al 1998 The upper
The beneficiation methods for Ethiopian Kenticha pegmatite spodumene ores were assessed through mineralogical and quantitative analyses with X ray diffraction XRD and energy dispersive X ray
The Ethiopian flood basalt province embraces the Afar triple rift junction where the African Rift System meets the Red Sea and Gulf of Aden sea floor spreading zones Prolific eruption of basalt and subordinate other lavas during Tertiary time has built up a subaerial volcanic pile typically 500 1500 m thick and locally attaining 3000 m This eruptive process was particularly active
Ethiopian flood basalt province has not been studied in sufficient detail to detect any 80 stratigraphic variations in the petrological and chemical compositions of the erupted lavas 81
