Significant geologic work has been accomplished on the cross-bedded Coconino Sandstone that compiles data for the marine origin rather than the aeolian origin of this formation. This data includes outcrop observations, microscopic thin section study (presence of mica, angular K-feldspars, dolomite, angular sand grains, and poor sorting), paleocurrent directions, paleontology, zircon crystal provenance, parabolic recumbent folds, and cross bed angles. Additionally, hydraulic flume experiments in the laboratory have studied the development of sand bedforms. This project will focus on similar field, laboratory and office research studies for other cross-bedded sandstones in the Western US and expand our understanding of their depositional environments.
