Coarse-grained alluvial and glacial out-wash deposits of Quaternary age are present in many of the lowland areas of Alaska and are known to yield large quantities of water in such places as Fairbanks and Anchorage. These coarse-grained deposits are likely to yield water in other places, if the deposits are unfrozen.The Quaternary alluvium is composed mainly of gravel, sand, clay and silt of diverse origins.

Duns are broad longitudinal intermontane depressions in the frontal parts of the Himalaya. Such basins are flanked by the outer Siwalik Hills in the south and the Lesser/Sub-Himalaya in the north. Duns consist of several landforms, prominent amongst which are relict surfaces, piedmonts, alluvial fans, floodplains, and river terraces.Substantial coarse clastics were carried by the Urumqi River from the range into the Chaiwopu basin and were deposited as the Quaternary alluvial fans (Fig. 1, Fig. 2). Pleistocene aeolian loess extensively mantles several high terrace surfaces developed by this piedmont fluvial system (Yang and Qiu, 1965, Zhang, 1981, Zhou et al., 2002). 3.The main bulk is a Tertiary sequence confined to the limits of the Cambay basin.

Most sedimentary material that fills a basin ("basin fill") that is not lithified is typically lumped together as "alluvial". Alluvium of Pliocene age occurs, for example, in parts of Idaho.The Quaternary alluvial deposits are unconformably overlying the Dihing Group (Pliocene) and are designated variously as 'Terrace deposits', 'Older or High levelUnconsolidated material.

Alluvium. Alluvium is a general term for clay, silt, sand and gravel. It is the unconsolidated detrital material deposited by a river, stream or other body of running water as a sorted or semi-sorted sediment in the bed of the stream or on its floodplain or delta, or as a cone or fan at the base of a mountain slope.
