All U.S. Government Documents (Utah Regional Depository)
A reconnaissance of ground water in the central Weber River area obtained data to help State administrators devise a policy for acting on applications to appropriate ground water resulting from recent and future influxes of residents.
Use Of Multispectral Scanner Images For Assessment Of Hydrothermal Alteration In The Marysvale, Utah, Mining Area, United States Geological Survey
Use Of Multispectral Scanner Images For Assessment Of Hydrothermal Alteration In The Marysvale, Utah, Mining Area, United States Geological Survey
All U.S. Government Documents (Utah Regional Depository)
Multispectral images of an area near Marysvale, Utah, were collected by using the airborne U.S. National Aeronautics and Space Administration (NASA) 24-channel Bendix multispectral scanner; they were analyzed to define areas of hydrothermally altered, potentially mineralized rocks. Hydrothermally altered rocks, particularly volcanic rocks affected by solutions rich in sulfuric acid, are commonly characterized by concentrations of argillic minerals such as alunite and kaolinite. These minerals are important for identifying hydrothermally altered rocks in multispectral images because they have an intense absorption band centered near a wavelength of 2.2 um. Unaltered volcanic rocks commonly lack these minerals and hence do not …
Bedrock Aquifers In The Northern San Rafael Swell Area, Utah, With Special Emphasis On The Navajo Sandstone, United States Geological Survey
Bedrock Aquifers In The Northern San Rafael Swell Area, Utah, With Special Emphasis On The Navajo Sandstone, United States Geological Survey
All U.S. Government Documents (Utah Regional Depository)
The northern San Rafael Swell area in southeastern Utah includes about 2,880 square miles (7,460 square kilometers) and ranges in altitude from about 3,290 to 7,921 feet (1,195 to 2,414 meters). Precipitation, the main source of water in the area, ranges from slightly less than 6 inches (152 millimeters) to slightly more than 12 inches (305 millimeters). Rocks that underlie the area range from Precambrian to Holocene in age. The thickness of sedimentary rocks ranges from 4,083 feet (1,244 meters) to about 30,000 feet (9,140 meters). The Entrada, Navajo, Wingate, and Coconino Sandstones and rocks of Mississippian age are considered …
