“…Two major regional (transcurrent) fault systems (Anka-Yauri-Iseyin-AYI and Kalangai-Zungeru-Ifewara-KZI fault systems) trending NE-SW occur in Nigeria and these had probably developed during the late Pan-African orogeny [31]. These fault systems are dextral wrench faults with displacements in the order of tens of kilometers and have associated locally developed conjugate sinistral faults [32]. The most prominent structural trends are the N-S planar structures but relicts of E-W, NW-SE and NE-SW structures are preserved [33,34].…”

Reconnaissance exploration for ore mineralization in Kaiama and environ have been carried out using integrated geological mapping and geochemical survey of soils, stream sediments and exposure of pegmatite/quartz veins. This was done in order to define the ore forming elements distribution and recognising type and area of possible mineralization in Kaiama and environ.. Eighteen samples were collected and analyzed for major and trace elements by x-ray fluorescence (XRF) and particle induced x-ray emission (PIXE) methods. Petrological description of thin sections of rocks was also carried out under the petrological microscope.The rocks underlying Kaiama consist of amphibolites, mica schists and granites along with fracture controlled mostly sheared mineralised pegmatite and quartz veins The fractured filled veins mainly trend NW-SE, NNE-SSW and E-W, N-S as to compare closely to the general trend of structures resulting from Pan-African orogeny. The mineralisation notably includes columbite-tantalite, rutile, cassiterites, ilmenites, wolframites, gold and gem stones. Geochemically, the trace elements concentrations shows significant anomalous concentrations of Sn, S, Ti, W, Au, Cu, Ti and Nb in the soil and stream sediments and Sn, W, and Nb in the veins. In addition, Zn, Cr, Co, Ni, Cd, Sb, Mo, V, As, Pb, Rb occurs in less significant anomalous concentrations in all the geologic media. The anomalous magnitude however decreases from soil to stream sediments and least in the veins. Further exploration work should be concentrated on soils and stream sediments towards delineating the possible ore deposit in the area of Kaiama and environs.

“…The older metasediments are deeply weathered and the hills in the area are covered with thick lateritic ironstone cover and exposures are difficult to find. This may explain why Turner (1983), Ajibade et al (1987) and Danbatta (1999;2003a) have mapped the area as a gneiss-migmatite-granite terrain.…”

“…The geology, structures, metamorphic history and mineralization of the KZSB have been summarized in a number of reports and papers, such as those of Morton (1967), Turner and Web (1974), Aderotoye (1977), Turner (1983), Ajibade et al (1987), Danbatta (1999;2001;2002;2003a) and Ibrahim (2002). These workers have shown that the belt consists of metasediments, metavolcanics and banded ironformations that are intruded by Pan-African Older Granites.…”

On the evolution of the Kazaure Schist Belt of NW Nigeria: a re-interpretation

All previous models of evolution of the Kazaure Schist Belt (KZSB) invoked a simple ensialic mechanism in the context of Pan-African deformation which led to the formation of a marginal back-arc basin floored by continental materials that accepted sediments. The closure of these basins in Pan-African times led to the deformation and metamorphism of the sediment and reactivation of older sediments. Taking into account the presence of Banded Iron Formations (BIFs), metavolcanics and the Kalangai-Zungeru-Ifewara (KZI) fault in the belt, a new model of its evolution is proposed. The new model of evolution of the KZSB considers the evolution of the belt by invoking a simple ensialic mechanism under extensional and compressional regimes, in the context of both Eburnean and Pan-African deformations, as well as Pan-African intrusion of calc-alkaline granites and volcanics. It is effective in explaining the occurrence of BIF, quartzites, conglomerates, and Pan-African granitoids in the belt; and emphasizes the presence of the KZI fault in the evolution of the Kazaure belt. The study led to the conclusion that the belt has formed through ensialic processes, and an evaluation of previous data suggested in previous works is consistent with the new view that the KZSB may represent remnants of Paleoproterozoic cover rocks infolded within an Archaean migmatite-gneiss complex during an Eburnean event, and become reactivated during the Neoproterozoic Pan-African event.

The application of geostatistics to data obtained from mineral prospecting can provide useful information for evaluating mineralization potential. The objectives of this study were to evaluate the spatial distribution of elements, establish relationships and understand chemical associations during mineral paragenesis in the studied area of Kaiama, Northcentral Nigeria. Major Oxide and Trace element analysis were carried out on 17 samples collected from three geologic media which are stream sediments, soils, and veins. The Geochemical results were subjected to multivariate statistical treatments in the form of correlation matrix (CM), Factor analysis (PCA), along with hierarchical cluster analysis (HCA) in order to classify the elements into groups that may signify common origin. All multivariate statistical tests were performed using SPSS (PASW Statistics 18) for Windows. The trace element geochemical composition shows significant anomalous concentration of Sn, W, Ta, Ti, and Fe. Au, Cu shows moderate to very high correlation. Areas of significant anomalous concentration were in the 2-4 km eastern outskirt of Kaiama and as well as 6-10 km south of Kaiama. Sn-W were more to the eastern outskirt while Sn-Ta were more in the southern part of Kaiama. All other trace elements V, Ni, Sr, Sb, Cd etc. shows low concentration with each other and are not significant in the mineralization of Kaiama. Further exploration work should be concentrated on soils and stream sediments towards delineating the possible ore deposit in the area of Kaiama and environs.
