Figure 6. Quantitative evaluation of minerals by scanning electron microscopy (QEMSCAN®) analyzing the micron-scale (2-μm) texture and chemical and mineralogical composition of a single central basin sample. (A–C) The textural characteristics of chlorite, illite, biotite, and kaolinite are shown. Only the clay minerals chlorite, illite, or kaolinite are colored. (D–F) The textural characteristics of all framework grains and matrix minerals are shown. All minerals are colored. Note that lithic fragments are typically chlorite rich. Musc. = muscovite.
