  • Table 1. Whole rock 40K/40Ar age dating of coarse-grained alkali feldspar granite from NBAC
  • Table 2. Representative electron microprobe analyses of clinopyroxene. Structural formulas calculated on the basis of 4 cations and 6 oxygen anions
  • Table 3. Representative electron microprobe analyses of Fe-Ti oxides. Structural formulas calculated on the basis of 3 cations and 4 oxygen anions for ulvöspinel-magnetite solid solutions and on the basis of 2 cations and 3 oxygen anions for ilmenite-hematite solid solutions. Usp: ulvöspinel; Mgt: magnetite; Ilm: ilmenite; Hem: hematite
  • Table 4. Representative electron microprobe analyses of feldspars. Structural formulas calculated on the basis of 5 cations and 8 oxygen anions
  • Table 5. Representative electron microprobe analyses of amphibole. Structural formulas calculated on the basis of 13 cations eCNK (except Ca, Na and K) and 23 oxygen anions
  • Table 6. Major elements (wt. %), trace elements, rare earth elements (ppm) and CIPW norm (wt. %) data for representative samples of the NBAC. The samples concerned by this investigation are quite fresh; those with LOI (loss on ignition) > 3% have been excluded. Fe2Ot = Fe2O3 total. For CIPW norms calculation, the values of Fe2O3/FeO ratios are indicated
