Fig. 8 shows the AF for each sample that was analyzed texturally, for both all grains (faded markers) and phenocryst grains (solid markers). Fig. 7 and 8 illlustrate that the intensity of SPO (both for all grains and phenocryst grains) observed in HC01 (the deepest sample) is the strongest, while SPO in BC302 (shallower) is weaker in intensity. BC11 (shallower than BC302), on the other hand, exhibits the weakest SPO. The shallowest sample, DS03, has the second most visible SPO. The SMG samples exhibit AFs that are inversely correlated with wt % SiO2. and Rb and positively correlated to Sr (Fig. 8). The AF of yellow samples in Fig. 8 (analyzed in later sections using unmixing model) correlate inversely with distance above deepest sample. The phenocryst population was identified in cross polarized light on the basis of interference color, euhedrality, lack of undulose extinction, and twinning (feldspars), and alteration and spottiness. Rose diagrams and the AF for all grains are included for comparison to ensure that bias introduced by manually assigning mineralogies to the identified grains is minimized.
