Abstract
This present study, the mapped area is located between latitude E07°35'00'' to E07°39'0011" and longitude N13°00'00'' to N12°57'00" of sheet 34NW, Katsina State, Northern Nigeria. The area is underlain by Basement Complex rocks and syeno-granitic rocks which dominate in the area. The two sets of granitic rocks were observed and distinguished by texture. The northwest of the mapped area consists of very coarse to coarse grained syeno-granitic rocks, while in the southeast, the rocks are medium to coarse grained. These outcrops exhibit various systems of joints. The mineralogical compositions determine by thin section results displays: quartz, biotite, muscovite, plagio-clase feldspar, apatite, sericite, hornblende, augite and microcline. There are two generalizations of joints with primary WSW to ENW direction and NE-SW, MMW-SSE and WWW-ESE secondary direction of NE-SW, MME-SSE and WWW-ESE.
Highlights
The rocks of the Basement Complex are divided into three (3) main groups
The ancient migmatite with subordinate gneiss and quartzite complex, the schist rocks and granites that are older than 650 million years commonly called the Pan-African granite suites (Bowden, 1982; Kankara, 2014) The most famous and notable tectonic igneous reactivation of this suite are attributable to the Pan African episode (Trompette, 1979)
Validity of the Eburnean event was highlighted. These Pre-Cambrian crystalline complex rocks cover nearly more than half of the surface of Nigerian territory and extend to neighbouring countries (Ajibade et al, 1987)
