Furthermore, the grain size analysis indicates that the grain size is medium to fine, which supports the proposed depositional system (Cant 1992 ; Radwan 2021a ).Thus, a critical control on the development of chlorite in sandstones is the primary depositional environment and the drainage of iron-enriched rocks in the hinterland. It is not possible to generate chlorite-enriched sandstones if the hinterland to the sedimentary basin is depleted in Fe-enriched rocks.

The average slope of cross-bedding does not have to be equal to 30 to 34 degrees, which is the maximum slope of dry sand, to be from a sand dune. The maximum slope of cross-bedding within the Coconino Sandstone does get as steep as 30 to 34 degrees (McKee 1979; Reineck and Singh 1980).These generalized facies and associations are called Facies Models.

The Tapeats Sandstone consists of a mixture shallow marine, intertidal, and coastal plain deposits associated with an eastward advancing shoreline. The upper transitional beds represent sediment deposited on a deepening shallow-marine shelf. Siltstone Depositional Environment. Siltstone is deposited in a similar environment to shale, but it often occurs closer to the shoreline of an ancient delta, lake or sea, where calmer currents cause less suspension of particles. ...
