Dune sand

A type of blown sand that has been piled up by the wind into a sand dune, usually consisting of rounded mineral grains, commonly quartz, having diameters ranging from 0.1 to 1 mm.

Arkansas - California - Colorado - Delaware - Florida - Georgia - Idaho - Maryland - Nevada - Virginia - Washington - Wyoming

Arkansas

Dune sand (Phanerozoic | Cenozoic | Quaternary | Pleistocene-Late): Dune sand - Deposited mostly on terrace deposits of the second level. Younger than some terrace deposits, older than others

California

Quaternary sand deposits, unit 1 (coastal) (Quaternary): Extensive marine and nonmarine sand deposits, generally near the coast or desert playas
Quaternary sand deposits, unit 2 (inland) (Quaternary): Extensive marine and nonmarine sand deposits, generally near the coast or desert playas

Colorado

Eolian deposits (Phanerozoic | Cenozoic | Quaternary): Includes dune sand and silt and Peoria Loess
Older eolian deposits (Phanerozoic | Cenozoic | Quaternary): Includes Loveland Loess

Delaware

Shore-line deposits (Pleistocene): Shore-line deposits - yellow and white, well-sorted, medium quartz sand of beaches and dunes

Florida

Dunes (Pliocene/Pleistocene): Dunes - Tertiary-Quaternary Dunes - The dune sediments are fine to medium quartz sand with varying amounts of disseminated organic matter. The sands form dunes at elevations greater than 100 feet (30 meters) msl.

Georgia

Aeolian sand deposits - parabolic dunes (Quaternary): Aeolian sand deposits - parabolic dunes

Idaho

Sand; Holocene dunes; Snake River Plain (Holocene): Recent active sand dunes and eolian deposits.

Maryland

Quaternary Deposits Undivided (Quaternary): Quaternary Deposits Undivided - Undifferentiated gray to buff sand and gravel, gray to brown lignitic silt and clay, occasional boulders, and rare shell beds. Surficial deposits occur as intercalated fluvial sands and marsh muds (e.g. in upstream floodplain of the Wicomico and Nanticoke Rivers), well-sorted, stablized dune sands (e.g. eastern Wicomico County), shell-bearing estuarine clays and silts (e.g. lower Dorchester County) and Pocomoke River basin of Worcester County), and beach zone sands (e.g. Fenwick and Assateague Islands). Wisconsin to Holocene in age. Subsurface deposits of pre-Wisconsin age consist of buff to reddish-brown sand and gravel locally incised into Miocene sediments (e.g. Salisbury area), estuarine to marine white to gray sands, and gray to blue, shell-bearing clays (e.g. Worcester County).

Nevada

Alluvial deposits (Quaternary): ALLUVIAL DEPOSITS-Locally includes beach and sand dune deposits

Virginia

Beach Sand and Dune Sand Deposits (Quaternary): Beach Sand and Dune Sand Deposits - Fine- to coarse-grained quartz sand, poorly to well-sorted.
Dune Sand (Quaternary): Dune Sand - Fine- to medium-grained, well-sorted quartz sand

Washington

Eolian deposits (Holocene): Active dune sand; includes beach sand along southwestern Washington coast.

Wyoming

Dune sand and loess (Phanerozoic | Cenozoic | Quaternary | Pleistocene Holocene): DUNE SAND AND LOESS--Includes active and dormant sand dunes. In northwestern Wyoming is chiefly loess (age 12,000-19,000 years).
