The area marked Franciscan Formation is underlain by solid sedimentary, igneous, and metamorphic rocks that are over 65 million years old.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.

Abstract. 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.Quaternary alluvium; may contain some glacial deposits and colluvium in uplands Gravel, sand, and silt; Quaternary basin-filling alluvium; Snake River Plain, Basin and Range provinces (Quaternary) Quaternary detritus; generally basin-filling deposits of central and southern Idaho.Most alluvium is Quaternary in age and is often referred to as "cover" because these sediments obscure the underlying bedrock. 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. Alluvium of late Miocene age occurs, for example, in the valley of the San Joaquin River, California. 8 de jan. de 2018 ...
