Field relationship and petrographic studies of metatexite and diatexite migmatites around Kagatu, Bauchi, Nigeria.

Muhammad Nafisatu Magaji.

Abstract
The study discoursed the field relationship and petrography of rocks of the study area. The geological mapping done on a scale of 1:25,000 indicated four diferrent morphological units occurring at Kagatu in the Northern Nigerian Basement Complex. The petrographic studies shows the presence of the various metamorphic and rock forming minerals which include quartz, olivine, orthoclase, orthopyroxene, plagioclase and graphite as observed under both plane and cross polarised lights. Also, field geology and petrographic analyses carried out from macroscopic to microscopic scale in the area revealed that the metatexite have coherent, pre-partial melting structures in the palaeosome to the absence of these structures in the neosome been replaced by syn-anatectic flow structures of the diatexite migmatites. Thus, these units are petrographically different but petrogenetially related to each other and to their protolith through partial melting and segregation of the melt from solid fraction.

Key words: Metatexite, Diatexite, Petrography, Partial melting.
