The Akokrowa range, confined by the following coordinates, N 7° 45′ 00″ to N 7° 41′ 25″ longitude and E 0° 21 00″ to E 0° 24′ 00″ latitude, covering a total area of 36 square kilometers spanning from Akokrowa to Okanease to Asukawkaw is distinguished on the basis of geological mapping into three distinct units, the lower unit (sandstones, and shales), the intermediate unit (a ferruginous rock suite) and the upper unit (an ophiolite suite and melteigite). The area is distinguished on the basis of geological mapping into three distinct units, the lower unit (sandstones, and shales), the intermediate unit (a ferruginous rock suite) and the upper unit (an ophiolite suite and melteigite).
The paragenetic evolution of the Akokrowa range of the BSU can be subdivided into five stages:
Stage I: Primary Fe-Si chemical sedimentation and early diagenesis
Stage II: Burial, deformation, and sedimentary iron stabilization
Stage III: Tectonic emplacement of mafic–ultramafic rocks and serpentinization
Stage IV: Hydrothermal sulfide introduction and metal redistribution
Stage V: Late oxidation, hematitization and iron upgrading
