The Navajo Sand­ stone at Zion is composed dominantly of small to large scale tabular and wedge planar tangential cross-strata that increase in thickness toward the top of the formation. Environmental interpretations of the Navajo Sandstone based upon modern textural studies were used, but The lithology of a reservoir impacts the petrophysical calculations in numerous ways. The depositional environment and sediments being deposited will define the grain size, its sorting, and its distribution within the reservoir interval. In most sandstone reservoirs, the depositional environment controls the porosity/permeability relationship.

When a depositional environment has sand in it and water or air moves the sand grains around, those grains can build up into piles of sediment. When the sediment piles reach a height where they are unstable - called the angle of repose - the grains will avalanche down the side of the pile and make a thin depositional layer of the grains that moved.Sandstone Depositional Environments has proven to be one of AAPG's all-time best sellers, with multiple reprints and extensive use as a university textbook.
