A) wt % SiO2, B) Sr concentration, C) Rb concentration, and D) distance above deepest sample of pluton as a function of alignment factor (AF). An alignment factor (AF) of 100 corresponds to populations of particles with identical orientations, while an alignment factor of 0 corresponds to no preferred orientation. Here, the distance above deepest sample is calculated by projecting the samples orthogonally onto the dashed, red line in panel A of Fig. 1. The distances are relative to the orthogonal projection of the deepest sample, represented by a red triangle in panel A of Fig. 1. Data points here correspond to samples shown in Fig. 7. Faded data points are AF values that correspond to all grains and completely opaque data points are AF values calculated for only feldspar and biotite phenocrysts. Samples in yellow are analyzed in later sections using unmixing model. All other samples are shown in white.
