This specimen is a sandstone. Detrital grains constitute about 75 percent of slide area, void space is approximately 10 to 15 percent, and the remaining area is occupied by fine grained matrix. Much of the void space is potentially the result of recent weathering or even slide preparation, formally filled by matrix. Most grains are subrounded to subangular. Of the detrital grains, quartz comprises about 60 percent of grains. Feldspars predominate among the remaining portion with opaques, micas, and lithic fragments contributing minimally. Based on these estimates this sandstone is classified as a feldspathic greywacke (this assumes much of the void space was originally fine-grained matrix). The constituent grains are well sorted. These observations suggest the parent material of detrital grains was mineralogically immature. Textural maturity is submature. Maximum grain size is .3 mm and minimum is .02 mm. The modal size is around .15 mm. Preserved matrix cement is predominantly composed of iron oxides/hydroxides and clay minerals, carbonates are also visible in some intergrain spaces and may be prevalent in less weathered samples. The cementing medium is what imparts the red color to the stone. There is a thin band of better preserved cementing medium with a relatively high iron mineral content about .6 mm wide. No visible macrostructure, such as bedding is visible in thin section. The hand sample presents only faint banding that is unlikely to be evident in a thin section.
