    The study area (Danko) is a part of the Zuru Schist Belt that comprises of Archean and Proterozoic rocks bearing the imprints of the Liberian, Eburnean and Pan-African orogenic events. Three deformational events have been identified (D1, D2 and D3) to have affected the rocks of the study area. The study uses Fry strain analysis method to digitize the center of the grains from which axial ratios and angles to reference lines of fifteen photomicrographs from low grade metasedimentary rocks (quartzites and muscovite schist) so as to understand their deformation pattern and strain history. Quartzite recorded a more intense strain history while muscovite schist recorded a slightly constrictive strain. This study attributes the discrepancy in strain values to be the result of a ductily contrast between the rock types. The majority of the strain in these rocks appears to come from D2 deforma..
