Mineralogical and Geochemical Characterization of Hydrothermal Alteration at Lynne Zn-Cu-Pb Deposit, Oneida Co. Wi.
(2021-04)
The purpose of this project is to determine the specific style of hydrothermal alteration that occurs within the volcanic strata at Lynne Zn-Cu-Pb deposit. The Lynne deposit is a volcanogenic massive sulfide deposit (VMS) ...
U-Pb Geochronology of Felsic Plutons in Neoarchean Sturgeon Lake Greenstone Belt, Ontario, Canada
(2021-04)
The emplacement of granitoid plutons in Archean granite-greenstone belt terranes can provide a more complete magmatic and deformational history than the volcanic and sedimentary rocks. Granitoid plutons in greenstone belts ...
GIS-Based Surficial Geology Map of Eau Claire County, West-Central Wisconsin, USA
(2021-04)
Eau Claire County is located in west-central Wisconsin, directly north of the unglaciated Driftless Area. A GIS-based 1:250,000-scale surficial geology map of Eau Claire County has been produced as part of a WGNHS project ...
A Case Study at Mud Lake : The Influence of Phosphorus Loading Through Lacustrine Groundwater Discharge on Eutrophication Events in a Stratified Flow-Through Lake in Western Wisconsin
(2021-04)
Phosphorus (P)-laden runoff has been associated with lake eutrophication throughout the upper Midwest United States. Although P has been considered immobile in groundwater systems, an ongoing investigation at UW-Eau Claire ...
Measuring Stream Baseflow Conditions in West Central Wisconsin
(2021-04)
This study seeks to measure baseflow conditions in West-Central Wisconsin to aid in determining the impacts of groundwater withdrawals on local streams. Streamflow is measured monthly at fourteen (14) sites across eleven ...
Role of Liquid Immiscibility and Sequential Extraction in the Evolution of the Bushveld Layered Mafic Intrusion, RSA
(2021-04)
The Bushveld layered mafic intrusion is the world’s largest magmatic body and hosts much of the known platinum, chromium, titanium, and vanadium reserves. The origin and magmatic evolution of the intrusion is still the ...
The Potential Role of the Choiyoi Eruptive Activity in the Great Permian Extinction
(2021-04)
The Great Permian Extinction occurred at the end of the Permian Period (~300-250 Ma), when 95% of marine and 70% of terrestrial life became extinct. The cause of this massive extinction event is still unknown, but it may ...
Three Dimensional Mapping of Eau Claire County Aquifers
(2021-04)
Groundwater is an important resource in west-central Wisconsin, and knowledge of the quantity of available groundwater is important for the environmental and economic well-being of the region. In recent years, greater ...
Characterizing Felsic Volcanic Rocks of the Lynne Zn-Cu-Pb Deposit, Oneida Co. Wisconsin
(2021-04)
The primary objective of this research was to describe the petrographic and geochemical characteristics of least-altered felsic volcaniclastic and coherent volcanic rocks that host Zn-Pb-Cu massive sulfides in the Lynne ...
Mineralogy and Petrology of Rare Element Pegmatites in The Eau Claire River Complex, Eau Claire County, WI
(2022-04)
Pegmatites are economically targeted for mining critical metals (Nb, Ta, Zr, Y, Th, U and REEs). The Eau Claire River pegmatite complex, originally mistaken as potassium-feldspar granite, are highly fractionated, garnet, ...
