| Lithology description: Majority occur in clean, white quartzite composed of fine to medium, subangular to subrounded quartz sand with 5% to 10% feldspar. Several specimes are preserved in impure (silty), medium-grained, arkosic sandstones containing 5% to 15% feldspar and commonly including small flakes of muscovite | |||
