Results

A total of 162 photomicrographs are included (Figs. F1, F2, F3, F4, F5, F6, F7, F8, F9, F10, F11, F12, F13, F14, F15, F16, F17, F18, F19, F20, F21, F22, F23, F24, F25, F26, F27). The sample number, lithic type, and lithostratigraphic unit of each photographed grain are included in Table T1. Lithic grains were grouped into sedimentary lithic fragments (SRFs) (Figs. F1, F2, F3, F4, F5, F6, F7, F8, F9), volcanic lithic fragments (VRFs) (Figs. F10, F11, F12, F13, F14, F15), plutonic lithic fragments (PRFs) (Figs. F16, F17, F18, F19), and metamorphic lithic fragments (MRFs) (Figs. F20, F21, F22, F23, F24, F25). SRFs were further divided into clay-rich (Figs. F1, F2, F3, F4, F5) and silt-rich (Figs. F6, F7A–F7D) mudstones, sandstones (Fig. F7E–F7F), argillaceous cherts (Fig. F8), and cherts (Fig. F9). VRFs were divided into felsitic (Figs. F10, F11), microlitic (Fig. F12), lathwork (Fig. F13), trachytic lathwork (Fig. F14), and pumice (Fig. F15). PRFs, with the exception of K-feldspar-quartz intergrowths (Fig. F18), were not divided. MRFs were divided into quartz rich (Fig. F20), quartz-mica rich (Fig. F21), micaceous (Fig. F22), chlorite rich (Fig. F23), epidote rich (Fig. F24), and others (Fig. F25). Petrographic definitions of each of these lithic fragment categories can be found in Marsaglia (1992), Marsaglia et al. (2013), and Milliken et al. (2007).

Grains that are not lithic fragments, such as poorly disaggregated muds (Fig. F26) or postdrilling sulfate precipitates (Fig. F27) were included under the category Artifacts.
