The uppermost part of the formation generally consists of a zone containing a very high percentage of calcium carbonate, variously called "cap rock", "lime rock", and caliche. ...The Neogene Ogallala Formation consists of discontinuous beds of conglomerate, sandstone, and siltstone composed of sediment eroded from the Rocky Mountains and deposited as a broad, eastward ...

Spatial patterns of lithium, fluoride, nitrate, chloride and bromide in the Ogallala Aquifer of northwestern Texas were mapped and evaluated. Solute concentrations and depths were compiled for 705 water wells sampled between 2008 and 2014. Lithium concentrations were high relative to typical groundwater; median and maximum concentrations were 66.8 and 2,790 ug/L, respectively. Almost half of ...

The Ogallala formation consists of fluviatile, late Tertiary (Neogene) deposits that underlie the surface that forms the High Plains. Ranging up to 300 feet in thickness, these deposits extend from Texas to South Dakota in a broad belt several hundred miles wide. Contrary to prevalent concepts, the Ogallala was not deposited as a series of ...In 2007, the market value from the Ogallala region's agricultural products totaled roughly $35 billion. However, well outputs in the central and southern parts of the aquifer are declining due to excessive pumping, and prolonged droughts have parched the area, bringing back Dust Bowl-style storms, according to the NCA4. ...Ogallala formation. Calcareous grit or soft limestone, sandy clay, and sand, with basal conglomerate at many places. Of late Tertiary (Pliocene?) age. Thickness 150 to 300 feet.

Ogallala Aquifer. The Ogallala Aquifer occupies the High Plains of the United States, extending northward from western Texas to South Dakota.The Ogallala is the leading geologic formation in what is known as the High Plains Aquifer System. The entire system underlies about 450,000 square kilometers (174,000 square miles) of eight states.

As this graph shows, depth to groundwater had a large range, varying from 33 to 379 feet. Most of the audited sites were extracting water from either the Rush Spring or Ogallala aquifers. The average groundwater depth was 104 feet for the wells tapping the Rush Spring and 273 feet for the Ogallala aquifers. Figure 5.

Aquifer first used for agriculture in 1800s.sediments and paleosols of the Ogallala Formation. During the trip, we will visit sites and landscapes that have a long and rich history of geologic investigation. In addi-tion to previously published results, we also present new data on the sedimentology, geochronology, paleontology, and paleoichnology of Cenozoic High Plains deposits.Ogallala Formation in Denver Basin. Hanna Formation (Paleocene) at surface, covers 5 % of this area. Brown and gray sandstone, shale, conglomerate, and coal; giant quartzite boulders near Medicine Bow Mountains. Lewis Shale (Upper Cretaceous) at surface, covers 5 % of this area.The Ogallala Formation is the time equivalent of part of the Santa Fe Group and other thick basin fills of the intermontane area, but is much thinner and more uniform in lithology because of its deposition on a rela-tively stable platform rather than in a complex of sinking basins. The source rocks of the Ogallala varied greatly throughplaces to examine the geologic history of the Ogallala Formation because they are much closer to the source areas of much of the sediment which makes up the unit than are other sites along the Ogallala outcrop belt. This study in Nebraska combined with results of earlier work there, in southeastern Wyoming, andAlthough the ground water in the Ogallala Formation in the Southern High Plains is common to both Texas and New Mexico, the State laws concerning ownership of the water are different. The New Mexico statutes provide that all under­ ground waters of the State belong to the public and are subject to appropriation for beneficialOgallala formation reveal that, in 1968, water withdrawn as groundwater from the Ogallala was almost twice as much as the total water usage from all the surface storage in the area. Most of the present withdrawals is for irrigation purposes; about 22% is for municipal and industrial use, and a small percentage is used in water-flooding of oil

The Ogallala formation consists of clay, silt, sandy silt, caliche, and cross-bedded sand and gravel (pl. 11B) which locally is cemented by calcium carbonate to a hard, "mortar bed" type of rock.
