| description | The Banket Series, which is a paleoplacer deposit, is the third formation in the stratigraphy of Tarkwaian
Supergroup. This project seeks to study petrographically; the lithologies in the banket series to confirm the
rocks identity as already known or state otherwise. Two different photomicrographs of each of the rock
samples, coupled by their petrographic descriptions were obtained from the laboratory. The main areas of
our arguments were based in Bowen’s reaction series, metamorphic facies of the rocks, the earth structure
and thermodynamic phase diagrams. The sampled rocks can be confirmed with the help of thin sections and
mineral facies to be conglomerate, dolerite and quartzite. The minerals in the banket series range in
temperature between 200°C and 800°C. The abundance of silica (SiO2) in the rocks conglomerate, dolerite
and quartzite are of crustal origin, whereas pyroxene and olivine originate from the upper mantle. The
common stable minerals in the studied rocks, namely, amphibole, chlorite and plagioclase are less likely to
change compared to the other minerals in the rocks. The three (3) different metamorphic facies of the rocks
conglomerate, dolerite and quartzite are respectively greenschist, epidote-amphibolite and amphibolite
facies.
