ABSTRACT
DEFORMATION AND FLUID INTERACTIONS IN THE MINERAL FORK DIAMICTITES,
ANTELOPE ISLAND, UTAH
by
Kimberly R. Johnson
The University of Wisconsin-Milwaukee, 2013
Under the Supervision of Professor Dyanna Czeck
Diamictite from the Mineral Fork Formation on Antelope Island, Utah was deformed to various degrees on the footwall of the Willard Thrust Fault during the Sevier Orogeny. The diamictite contains clasts of differing strength resulting in quartzite clasts deformed the least, pink granitic clasts deformed to a greater degree, and softer green gneissic clasts deformed the most. The pink granitic and green gneissic clasts have similar compositions, but deform differently. This …
Development Of Green Solvent Modified Zeolite (Gsmz) For The Removal Of Chemical Contaminants From Water, Elizabeth Stapleton
Development Of Green Solvent Modified Zeolite (Gsmz) For The Removal Of Chemical Contaminants From Water, Elizabeth Stapleton
Theses and Dissertations
Sorption represents an important strategy in the remediation of groundwater contamination. As a naturally-occurring mineral with large cation exchange capacity, zeolite is negatively charged and has been widely used as an inexpensive and effective sorbent for the removal of positively charged contaminants. The negative charges of zeolite, however, make it generally ineffective in the sorption of anionic contaminants such as chromate and arsenate. In order to improve the capacity for sorption of anionic species, the surface charge of the zeolite must be modified. Cationic surfactants can be used to alter the surface charge of the minerals so that the negatively …
Applying Geochemistry To Investigate The Occurrence Of Riverbank Inducement Into A Shallow Aquifer In Southeastern Wisconsin, Anna Maria Thorp
Applying Geochemistry To Investigate The Occurrence Of Riverbank Inducement Into A Shallow Aquifer In Southeastern Wisconsin, Anna Maria Thorp
Theses and Dissertations
Increased urbanization in southeastern Wisconsin has led to significant drawdown in both the shallow and deep aquifer. In Waukesha County combined radium activity levels exceeding the limit set forth by the USEPA have been detected within the deep aquifer. This has prompted the community to consider alternative, long term, drinking water supply solutions.
One possible solution is riverbank inducement (RBI), in which river water is induced into the adjacent aquifer as recharge. This would make the shallow aquifer an effective addendum to growing water supply demands, and reduce the effects of excessive pumping. Using basic geochemical analyses, this study examines …
Re-Examination Of Changes In Fluvial Stacking Pattern Across The P-T Boundary In The Central Transantarctic Mountains, Antarctica, Danielle Sieger
Re-Examination Of Changes In Fluvial Stacking Pattern Across The P-T Boundary In The Central Transantarctic Mountains, Antarctica, Danielle Sieger
Theses and Dissertations
A change in fluvial style and a change in the stacking pattern of fluvial channel sandstone bodies occur across the Buckley‒Fremouw formational contact in the central Transantarctic Mountains in Antarctica. Strata in the Buckley Formation are characterized by thick floodplain deposits in the Middle to Upper Permian Buckley Formation; whereas, stacked interconnected sandstone bodies occur in the Triassic Fremouw Formation (Barrett et al., 1986; Isbell & Macdonald, 1991a, 1991b; Collinson et al., 1994; Isbell et al., 1997; 2005). Such changes in fluvial stacking patterns have been attributed to changes in the creation of accommodation within basins due to changes in …
Late Paleozoic Glaciation And Ice Sheet Collapse Over Western And Eastern Gondwana: Sedimentology And Stratigraphy Of Glacial To Post-Glacial Strata In Western Argentina And Tasmania, Australia, Lindsey C. Henry
Theses and Dissertations
The late Paleozoic ice age (LPIA; 345-280 million years ago) provides the last complete record of a major deglaciation on a vegetated Earth, and therefore can serve as a proxy for Earth's inevitable transition out of its present glaciated state. This project analyzes climate change during and following the LPIA using two different approaches:
1) Detailed sedimentology analyses of five glacially-influenced formations in Argentina and Australia in order to determine the size and thermal regime of glaciers during the LPIA.
2) An investigation of massive volcanism along the Panthalassan margin of Gondwana as a source of CO2 that may have …
Regionalization Of Hydrologic Response In The Great Lakes Basin: Considerations Of Temporal Variability, Jonathan Martin Kult
Regionalization Of Hydrologic Response In The Great Lakes Basin: Considerations Of Temporal Variability, Jonathan Martin Kult
Theses and Dissertations
Methods for predicting streamflow in areas with limited or nonexistent measures of hydrologic response commonly rely on regionalization techniques, where knowledge pertaining to gaged watersheds is transferred to ungaged watersheds. Hydrologic response indices have frequently been employed in contemporary regionalization research related to predictions in ungaged basins. In this study, regionalization models were developed using multiple linear regression and regression tree analysis to derive relationships between hydrologic response and watershed physical characteristics for 163 watersheds in the Great Lakes basin. These models provide a means for predicting runoff in ungaged basins at a monthly time step without implementation of any …
