Sandstone and mudstone with wavy bedding toward the east and mudcracks toward the west. Fine sandstone with symmetrical ripple marks. Sandstone that contains more than 90% quartz is called quartzose sandstone. When the sandstone contains more than 25% feldspar, it is called arkose or arkosic sandstone. When there is a significant amount of clay or silt, geologists refer to the rock as argillaceous sandstone. The color of sandstone varies, depending on its composition. 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.

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.

Salt Lake Community College via OpenGeology. Figure 7.5.1 7.5. 1: A representation of common depositional environments. The ultimate goal of many stratigraphy studies is to understand the original depositional environment. Petrographic classifications of sand and sandstone proposed more than half a century ago are still in use, although they were formulated at a time when depositional and post-depositional sedimentary processes were poorly understood, and before the relationships between tectonics and sedimentation could be interpreted in modern plate-tectonic terms.
