Aeromagnetic data and Landsat image, were assessed to establish a relationship between morphostructural feature borehole yield of sub-basin Osun basin in the Northern part Ilesha, southwestern Nigeria. Four factors (Geomorphological unit, Slope, regional structure, lineament) considered. Geomorphological units classified based on digital elevation model (DEM), Lineaments identified extracted us...

Abstract Garnet–kyanite–staurolite assemblages with large, late porphyroblasts of amphibole form garbenschists in Ordovician volcaniclastic rocks lying immediately south the Pearya terrane on northernmost Ellesmere Island, Canada. The schist, which together carbonate olistoliths makes up Petersen Bay Assemblage (PBA), displays a series parallel isograds that mark an increase metamorphic grade o...
