Title: Geophysical Evaluation of Gold Potential in Southeastern Part of Kafin-Koro, Northwestern Nigeria Authors: Alabi, Abdullahi, S. A. A. Abstract: Gold mineralization in Nigeria is traversed by regional northwest - southeast lineaments or shear zone which have been considered as continental extension of oceanic transform fault - fracture zone, and it is suggested that the migmatization and metamorphic deformation of the metasedimentary and metavolcanic rocks gave rise to dispersion of gold in quartz veins within the Nigeria basement complex. Combined geophysicaln methods have been used in the exploration for ore mineral bodies. Induced polarization (IP) technique has proved favourable for mineral exploration in hard rock terrain, as well as for ground water exploration and environmental geology studies. Also, magnetic technique has been used in identifying massive sulfide hosted quartz veins. The study area lies within the Kushaka schist Formation of the north-western block of Nigeria basement complex and Nigeria metallogeny province, the formation has been intruded by large volumes of granitic rocks that led to extensive migmatization of metasedimentary and metavolcanic rocks carrying substantial gold mineralization. Combined magnetic and IP and resistivity imaging technique was used in the study. The magnetic profiles in the study area showed anomalies of varying amplitudes. The variation in amplitudes of the residual intensity may be due to the presence of geological structures such as faults, dykes and contacts in the area. The total magnetic intensity map of the area exhibits zonation and alteration that indicates hydrothermal alteration which is usually associated with mineralization probably as a result of intrusion. Observed apparent resistivity and IP data presented as pseudo-section and 2-D inverted resistivity-IP mode shows a qualitative idea of resistivity and chargeability distribution in the subsurface. The ground magnetic survey generally suggests a step or an edge structures like dyke or intrusion, such structures are of interest may hold mineralization at certain depth. Description: xxxx

Title: A Self-Starting Block Methods (SSBMs) for the Solution of Ordinary Differential Equations Authors: Bako, Deborah; IBRAHIM, Sani Doro; SAGIR, Abdu Masanawa Abstract: In this paper, self-starting block numerical methods for the solution of stiff initial value problems ordinary differential equations were developed. The Backward Differentiation Formulas and Generalized Backward Differentiation Formulas are used in the derivations. The E-transformation is applied to the triples and self-starting methods are obtained. The numerical implementation of the methods on ordinary differential equations are reported to show the effectiveness and efficiency of the methods. The computational of convergence of absolute stability and consistent tends to the theoretical order as h tends to zero

Title: Geoelectrical Prospecting for Fractured Basement Aquifer in Northern Portion of Futminna's Bosso Campus, Minna, North Central Nigeria Authors: Alabi A. A.; Christopher Unuevho; Amadi Akobundu Nwanosike Abstract: Only one out of three boreholes in the northern portion of FUTMINNA's Bosso Campus is productive. Values of hydrogeophysical parameters characterising fracture column at the productive borehole site were captured from vertical electrical resistivity and spontaneous potential (SP) sounding data. The values were employed to identify other sites with potential for groundwater production in the area. Sounding locations LI, L8, L14, L19 and L20 contain fracture column characterised by 200-400?m resistivity: -10 to 20mV SP. 1200-2400?m² transverse unit resistance and 0.05-0.1?' longitudinal unit conductance. Boreholes sited at these locations would be productive because the fracture column therein has identical values of hydrogeophysical parameters with the fracture column at the productive borehole site. Sounding locations 14 and 20 were found to be groundwater convergence zones respectively within north-western and eastern portions of the investigated area. The fracture column in the vicinity of sounding location 20 is thickest and more spatially extensive, thereby making the eastern sector the most suitable for drilling productive borehole Description: xx

Title: GEOLOGY AND INDUSTRIAL APPLICATIONS OF KWAKUTI MARBLE, NORTH-WETERN NIGERIA Authors: Alabi. A. A., Olasupo, B. A. Abstract: Carbonate sedimentary rock formed at the bottom of lakes and seas as silt and organic matter that settle from the water body to the bottom. It is formed as a result of the recrystallization of limestone. It is composed essentially of calcite (CaCO3), but it is called dolomite CaMg(CO3)2 when its magnesium content is high. Generally pure marble is composed of total CaCO3 content of between 97% - 99%, and pure dolomite is composed of 45.7% MgCO3 and 54.3% CaCO3 or 30.4% lime (CaO) and 21.8% magnesia (MgO). Despite abundant reserves of marble, not very much of the country’s marble has been properly utilized. Kwakuti marble has so far been underutilized, therefore this research will unravel geology and economic potential of the study marble. Ten (10) samples of marble were selected for analysis using XRD and XRF techniques. Comparison of the chemical composition of Kwakuti marble with typical calcitic and dolomitic marbles; the Kwakuti marble compare favourably with typical calcitic marbles from different environments. Comparing the study marble to standard and specification it revealed that the Kwakuti marble is well suitable for agricultural productions. Description: xxxx
