Figure F12. Relationship between two discriminant functions (DFs) (Roser and Korsch, 1988) for the sediment samples from Site 1179. DF 1 = 30.638 TiO2/Al2O3 – 12.541 Fe2O3(total)/Al2O3 + 7.329 MgO/Al2O3 + 12.031 Na2O/Al2O3 + 35.402 K2O/Al2O3 – 6.382. DF 2 = 56.500 TiO2/Al2O3 – 10.879 Fe2O3(total)/Al2O3 + 30.875 MgO/Al2O3 – 5.404 Na2O/Al2O3 + 11.112 K2O/Al2O3 – 3.89.
