GEOLOGY OF OSO EDDA AND ITS ENVIRONS

📄 Project Abstract

Oso Edda and environs is located within the flank of the Afikpo Basin and detailed geologic mapping was done in other to determine the various stratigraphic framework using the basic field and laboratory procedures. Field observations on exposed outcrops indicated that the study area consists of three basic lithologic units based on the general orientation of the rocks, sample identification and structural observations. These three units are all dipping southeastly towards the centre of the basin. The basal older Unit (Unit 1) is an interbedding of a highly indurated slaty cleavaged shale, calcareous rock and sand stone respectively, whose depositional environment is believed to be shallow marine based on the micro paleontologic and palynological evidence obtained from the shale bed. The shales are fractured and the careous rock is highly jointing showing an extesional type of deformation. This unit is dipping in a SSE direction whose average dip is about 760. It is thought to be affec...
