Controls on the regional-scale salinization of the Ogallala aquifer, Southern High Plains, Texas, USA
An extensive saline plume (>250 km) within the regionally important uncon®ned aquifer in the Neogene Ogallala Formation overlies the Panhandle oil and gas ®eld in the Southern High Plains, Texas, USA. Relative to upgradient Ogallala water, the plume waters have dO (ÿ6.7 to ÿ8.8-) and dD (ÿ42 to ÿ88-) values that tend to be depleted and have higher Cl (>150 mg/l) and SO4 (>75 mg/l) concentration...
متن کاملElevated naturally occurring arsenic in a semiarid oxidizing system, Southern High Plains aquifer, Texas, USA
High groundwater As concentrations in oxidizing systems are generally associated with As adsorption onto hydrous metal (Al, Fe or Mn) oxides and mobilization with increased pH. The objective of this study was to evaluate the distribution, sources and mobilization mechanisms of As in the Southern High Plains (SHP) aquifer, Texas, relative to those in other semiarid, oxidizing systems. Elevated g...
متن کاملDistinctive upper mantle anisotropy beneath the High Lava Plains and Eastern Snake River Plain, Pacific Northwest, USA
[1] The Pacific Northwest (PNW) has experienced voluminous intraplate volcanism over the past 17 Ma, beginning with the Steens/Columbia River flood basalts and continuing with the stillongoing volcanism in the High Lava Plains (HLP) and eastern Snake River Plain (SRP). Here we present two complementary datasets (SKS splitting and Rayleigh wave phase velocity anisotropy) that place constraints o...
متن کاملOrigin of late Quaternary dune fields on the Southern High Plains of Texas and New Mexico
Mostly stabilized late Holocene eolian sands on the Southern High Plains of the United States were studied to determine their origins and to assess whether present dune stability depends more strongly on sediment supply, sediment availability, or transport limitations. Geomorphic, sedimentological, and geochemical trends indicate that late Holocene dunes formed under westerly paleowinds, broadl...
متن کاملRoundup Ready versus Conventional Cotton Varieties: Case Studies from the Southern High Plains Region of Texas
This paper compares the profitability and cost of production of irrigated Roundup Ready cotton varieties and conventional cotton varieties grown under crop share rental agreements in the Texas High Plains Region for 1998. The Standardized Performance Analysis (SPA) program was used to analyze 25 sub-enterprises for each variety type from six producers selected from the regional SPA database for...
