| dc.description.abstract | This work presents the Geology and Petrography of rocks around Kadna part of Minna Sheet 164 SW North Central Nigeria which lies within latitudes 9°33’00”N to 9° 34’15’ N and longitudes 6035’00” E to 6° 37’305,E on a scale of 1:25 000 with the aim of studying the detail geology through petrography of rocks in the area, delineate geologic boundaries between different rocks, identify the economic viability of the rocks and to produce the geologic map and cross section of the area. Geologically, the study area is part of the .1 : : !j Precambrian Basement Complex of North Central Nigeria. Three different schists were mapped, namely: biotite schist, amphibolite schist and garnet bearing schist. Three representative samples were collected systematically from the fifteen field samples and were ; taken to the petrography laboratory of the Department of Geology and Mining, Nasarawa State University Keffi for petrographic analysis. Results of the petrographic analysis revealed that the major mineral composition of Biotite schist include biotite, muscovite and quartz. i The mineral composition of the amphibolite schist include muscovite, biotite and quartz. j Also the petrographic studies reveals that the garnet bearing schist composed of garnet, muscovite, and biotite. Structurally, the biotite schist is characterized by fractures which are formed as a result of tensile strain on the rock surface and veinlets which both trends in NNESSW and NW-SW. The joints on the amphibolite schist majorly trends NE-SW, NNE-SSW and occurs as a set consisting of some parallel joints together. Veinlets observed on the garnet bearing schist are mainly quartz veins which trends NW-SE, NE-SW. From the field observations and the result of the petrographic analysis, the rocks around Kadna are believed to be metasediments of the Precambrian Basement Complex of North-Central Nigeria. | en_US |
