More than 50% of the excavated stone is wasted in the form of scrap stone and waste slurry during sandstone quarrying and processing. High‐energy environments such as steep river channels usually deposit coarse arkosic sandstones or conglomerates. Beaches and barrier islands consist of well‐rounded quartz sandstone. Lower‐energy environments like lake beds, deltas, lagoons, and the deep ocean can be identified by the finer‐grained rocks such as shale and siltstone.

INTERPRETATION OF DEPOSITIONAL ENVIRONMENTS. The White Rim Sandstone Member in Canyonlands National Park was deposited in an eolian system. Unlike many other depositional environments, no single facies model exists for eolian systems, resulting in no preferred vertical sequences nor any consistent lateral changes (Walker, 1979).

Conglomerate is a clastic sedimentary rock made up of rounded clasts that are greater than two millimeters in diameter. The spaces between the clasts are generally filled with sand- and clay-size particles. The rock is bound together by a cement that is usually composed of calcite or quartz.
