Ogallala formation
In Kansas, the aquifer comprises three components — the Ogallala aquifer, the Great Bend Prairie aquifer and the Equus Beds. Of these, the Ogallala aquifer underlies most of western Kansas and consists mainly of the Ogallala Formation, a geologic unit that formed from sediment eroded off the uplifting Rocky Mountains.The fossil seeds from the Ogallala formation (Pl. 8, 9; Fig. 4) may be divided into three major, stratigraphically significant groups: (1) seeds that occur in the Valentine member, represented in Kansas by a single species of grass, Stipidium commune; (2) a large assortment of grasses and other herbs characteristic of the Ash Hollow member ...

Ogallala Formation (Pliocene) at surface, covers 25 % of this area. ... about 100 to 130 feet thick, thinning northward. This formation has 2 gypsum and (or) dolomite beds in upper 20 feet--the "Emanuel Bed" (at top) and the "Relay Creek Bed" (20 feet below top). Two thin, pale shales occur; the first is 1 foot below the top ("Gracemont") and ...The Tertiary Ogallala Formation directly overlies the Permian red beds, although Triassic sedimentary rocks are present in the southwestern part of Lake Meredith NRA. The approximately 10-million-year-old Ogallala Formation is much younger than the underlying rocks, and sits atop a regional uncomformity, or period of missing time. ...From Wikipedia, the free encyclopedia.

Ogallala Formation strata in Scott County, Kansas, are composed of pedogenically modified silts, sands, and gravels interbedded with massive calcretes. Though ichnofossils are present throughout ...The hydraulic gradient in the Ogallala Formation is approximately 12 feet per mile across the county. Aquifer tests indicate an average permeability of about 900 gpd per square foot. With an assumed porosity of 30 percent, the average velocity of the ground water is calculated to be v = (900 x 12) / (395 x 30) = 0.9 foot per day, orThe fossil seeds from the Ogallala formation (Pl. 8, 9; Fig. 4) may be divided into three major, stratigraphically significant groups: (1) seeds that occur in the Valentine member, represented in Kansas by a single species of grass, Stipidium commune; (2) a large assortment of grasses and other herbs characteristic of the Ash Hollow member ...A better understanding of the Ogallala Formation is critical in terms of refining groundwater flow models and management policies for communities relying on aquifers in heterolithic sequences around the globe. The High Plains aquifer remains under increasing stress with the growth of both urban and agricultural areas and therefore, developing the best groundwater management policies will ...

By far, the High Plains/Ogallala aquifer is the largest in terms of volume of water in storage and withdrawals for irrigation. Several secondary aquifers exist in areas outside of the High Plains aquifer, providing water for irrigation, municipal supplies, and domestic use in parts of far western and far eastern Nebraska. ….

Ogallala Formation of eastern New Mexico has been divided into zones on the basis of the composition of the contained clay minerals (Frye, Glass, Leonard, and Coleman, 1974). These clay-mineral zones are distinc-tive and have been recognized from the southeastern part of the state (Leonard, Frye, and Glass, 1975)The smallest video file formats are WMV, FLV, MPEG-4 and RealVideo. These formats can be used to create videos or to stream them.Map of the Ogallala Aquifer. Lubbock, Texas, the Hub City of the South Plains, sits atop the southern range of the Ogallala Aquifer. Thanks to this massive natural formation, in this part of the world, cotton is king because center-pivot irrigation lapping up the fossil water of the Ogallala Aquifer has made these sunny grasslands highly productive.
