A) Orientation for textural analysis and analysis results for B) DS03, C) BC11, D) BC302, and E) HC01. A) Schematic showing the plane in which thin sections were prepared relative to original orientation (pre-tilting) of SMB. The left panel in B, C, D, and E includes identified grains and grain boundaries, the identification of which is described in the main text. Each color corresponds to an individual grain and has no relation to mineralogy. The right panel in B, C, D, and E includes identified grains and grain boundaries, but feldspar and biotite phenocrysts have been highlighted with a pink-ish hue and all other grains with tan-ish hue. The right panel in B, C, D, and E also includes rose diagrams which display the number of grains whose long axis is aligned at a given angle. The tan rose diagrams include all grains (no mineralogic distinction), while pink rose diagrams only take into account feldspar and biotite phenocrysts. The AF (alignment factor), which describes the extent of foliation, of each grain population is tabulated and displayed with the rose diagrams. The angles are measured with respect to the bottom edge of the image.
