Figure 6. (A) The Total Alkali silica TAS (K2O+Na₂O vs. SiO₂) classification diagram of for the Nkor Noni basaltic dyke. The line after delineates the boundary between alkaline and subalkaline domains; (B) Total alkali-Silica classification diagram of for Nkor Noni basaltic dykes. The line after delineates the boundary between alkaline and tholeiitic domain; (C) Fe₂O₃ vs. MgO classification diagram of for the Nkor Noni basaltic dykes showing low Mg- characteristics
