The Geochemistry Of Matrix Of Metaconglomerate In Igarra South-Western, Nigeria

Geochemical exploration of Igarra district within the Igarra schist belt in southwestern Nigeriawas carried out using geological field mapping with the aim of determining the elementalcomposition of the matrix in metalonglomerate. A total of 15 samples were collected. Chemicalanalysis of 11 trace elements (Cr, Mn, Ni, Ti, V, Sr, Pb, Ba, La, Zn, and Cu) and 7 majorelements (P, K, Al, Mg, Fe, Ca, and Na) were carried out. The analytical results were subjectedto univariate statistical analysis in order to determine the elemental compositions of the matrixvia histogram. There are different in the concentration and percentage in the trace element andmajor element respectively in (MB1 to MB15). Barium has the highest and Titanium has thelowest in the elemental distribution of the trace element while Phosphorus has the highest andSodium has the lowest in the elemental distribution of the major elements. Two individual traceelement (Manganese and Lanthanium) show similarity in their concentration in (ppm)throughout the samples (MB1 and MB15). Magnesium and Strontium are below the detectionlimit in the geochemical analysis data, i.e. they are extremely low in the elemental compositionof the matrix. From the geochemical analysis, the trace element is more abundance than themajor element in the matrix of metalonglomerate. The occurrence of pathfinder elements such asNickel and Lead within the schist belt that could serve as hosts for mineralization of theseelements, provides a strong basis for this assertion.
