Relationship Between Fault Zone Architecture And Groundwater Compartmentalization In The East Tintic Mining District, Utah, Sandra Myrtle Conrad Hamaker
Relationship Between Fault Zone Architecture And Groundwater Compartmentalization In The East Tintic Mining District, Utah, Sandra Myrtle Conrad Hamaker
Theses and Dissertations
The Eureka Lilly fault zone provides an impermeable barrier for groundwater flow in the East Tintic mining district. The fault zone separates two distinct groundwaters that have different temperatures, compositions, and potentiometric surfaces. The damage zone of the fault is an extensive network of interconnected open fractures and fault intersections that provide conduits for groundwater flow in otherwise impermeable units. The fault core breccia has been re-cemented and mineralized, which eliminates porosity in the rock by creating a thick impermeable zone, which has compartmentalized groundwaters across the fault zone. The compartmentalization of groundwater shows that fault zone variability (from strain …
Effects Of Hurricane Fault Architecture On Groundwater Flow In The Timpoweap Canyon Of Southwestern, Utah, Sarah J. Dutson
Effects Of Hurricane Fault Architecture On Groundwater Flow In The Timpoweap Canyon Of Southwestern, Utah, Sarah J. Dutson
Theses and Dissertations
Hydrogeologically important features of fault zones include undamaged country rock, the damage zone, and the core zone. Fault cores generally have low porosity and permeability, and often act as a barrier to groundwater flow. The damage zone, by contrast, consists of small faults and fracture networks, which can act as conduits. Timpoweap Canyon near Hurricane, Utah has superb exposures of the fault core and damage zone of the Hurricane Fault. Also within the canyon, springs discharge from the damage zone into the Virgin River, providing an ideal natural laboratory for the study of groundwater discharge from a fault zone. The …
Hydrogeophysical Investigation At Luxor, Southern Egypt, Ahmed Ismail, Neil Lennart Anderson, J. David Rogers
Hydrogeophysical Investigation At Luxor, Southern Egypt, Ahmed Ismail, Neil Lennart Anderson, J. David Rogers
Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works
Over the past 35 years, the exposed stone foundations of the ancient Egyptian monuments at Luxor have deteriorated at an alarmingly accelerated rate. Accelerated deterioration is attributable to three principal factors: 1) excavation and exposure of foundation stone; 2) construction of the Aswan High Dam; and 3) changes in the regional groundwater regime. In an effort to better elucidate the hydrostratigraphy in the Luxor study area that extends from the River Nile to the boundaries of the Nile Valley and covers about 70 km2, a geophysical/hydrological investigation was conducted. Forty Schlumberger vertical electrical soundings (VES), two approximately 6 …
Groundwater Quality In Kentucky: Mercury, Bart Davidson, R. Stephen Fisher
Groundwater Quality In Kentucky: Mercury, Bart Davidson, R. Stephen Fisher
Information Circular--KGS
Mercury is a naturally occurring metal that occurs in trace amounts in water, soils, and rocks. Elemental mercury is a liquid that occurs in some ore deposits; it may also be concentrated around hot springs. Currently, about 50 percent of mercury use is for electrical products such as dry-cell batteries, fluorescent lights, switches, and other control equipment. Mercury is also used in the electrolytic preparation of chlorine gas and caustic soda, and in paint manufacture and pesticide production (U.S. Environmental Protection Agency, 2002). In the past, significant amounts of mercury were used in thermometers and pressure gauges.
Groundwater Quality In Kentucky: Selenium, Bart Davidson, R. Stephen Fisher
Groundwater Quality In Kentucky: Selenium, Bart Davidson, R. Stephen Fisher
Information Circular--KGS
Selenium is a naturally occurring element found in most rocks and soils (Agency for Toxic Substances and Disease Registry, 2003). In its solid form, selenium is black, gray, or red and is odorless (New Jersey Department of Health and Senior Services, 2002). Most selenium is obtained from byproducts of the copper refining industry. Selenium compounds are often used in electronic components, photocopiers, metal alloys, rubber, paint pigments, glass-making (ruby red glass), and photographic emulsions (U.S. Environmental Protection Agency, 2003). Selenium exhibits both photovoltaic and photoconductive properties. As more light shines on selenium, its electrical conductivity increases, making it extremely useful …
Groundwater Quality In Kentucky: Cadmium, Bart Davidson, R. Stephen Fisher
Groundwater Quality In Kentucky: Cadmium, Bart Davidson, R. Stephen Fisher
Information Circular--KGS
Cadmium is a metallic element that occurs naturally in the earth's crust, especially in zinc-, lead-, and copper-bearing ores (Forstner and Whittmann, 1981). Pure cadmium is a soft silver-white metal, but is rarely found naturally in its pure form. It is commonly combined with other elements, such as oxygen (cadmium oxide) and sulfur (cadmium sulfate).
Generalized Geologic Map For Land-Use Planning: Gallatin County, Kentucky, Richard A. Smath, Bart Davidson, Daniel I. Carey, John D. Kiefer, Ken Daniels
Generalized Geologic Map For Land-Use Planning: Gallatin County, Kentucky, Richard A. Smath, Bart Davidson, Daniel I. Carey, John D. Kiefer, Ken Daniels
Map and Chart--KGS
This map is not intended to be used for selecting individual sites. Its purpose is to inform land-use planners, government officials, and the public in a general way about geologic bedrock conditions that affect the selection of sites for various purposes. The properties of thick soils may supercede those of the underlying bedrock and should be considered on a site-to-site basis. At any site, it is important to understand the characteristics of both the soils and the underlying rock.
