| Eolian sands develop in arid settings and commonly form extensive, blanket-like deposits (Figure 3b). Wind transport removes fines and produces rounded and extremely well sorted grains often leading to favorable reservoir quality. | | Eolian sands develop in arid settings and commonly form extensive, blanket-like deposits (Figure 3b).

− | This combination of widespread occurrence and good reservoir properties makes eolian sandstones attractive exploration targets and many hydrocarbon accumulations have been discovered in such deposits (see <ref name=pt06r2>Ahlbrandt, T.

| Eolian deposits include dune, interdune, sand sheets (marginal to dune complex), and extradune (noneolian) lateral deposits.<ref name=pt06r2 />) Dune deposits comprise the major sedimentary bodies in eolian successions. All are characterized by large scale cross stratification in which foreset dips range up to 35°. Associated deposits may include those of wadi (fluvial), playa (lacustrine), and sabkha (arid tidal flat) origin. | | Eolian deposits include dune, interdune, sand sheets (marginal to dune complex), and extradune (noneolian) lateral deposits.<ref name=pt06r2 />) Dune deposits comprise the major sedimentary bodies in eolian successions.
