Komatiite-Hosted Nickel-Copper Mineralization Potential in the Eastern Shebandowan Greenstone Belt, Ontario, Canada
(2018-05)
Our research focuses on geochemical and textural evidence of interactions between Archean komatiites and silicic sedimentary rocks near Thunder Bay, Ontario, and exploring the potential for Nickel-Copper-Platinum Group ...
Compilation of Historic Mineral Exploration Data Pertaining to the “Lost” Crandon Cu-Zn Deposit, Forest County, WI : Rediscovering Wisconsin’s Largest and Most Controversial Massive Sulfide Deposit
(2018-03-28)
The Crandon massive sulfide deposit in Forest County, Wisconsin, is by far the largest polymetallic ore body in the Penokean Orogen. First discovered in 1976 by the Exxon Minerals Co., the company was eager to exploit the ...
Three-Dimensional Modeling and Reconstruction of the Crandon Volcanogenic Massive Sulfide Deposit, Northeastern Wisconsin
(2018-05)
The goal of this research project is to determine the petrogenesis of the stratigraphy hosting the Crandon Cu-Zn volcanogenic massive sulfide (VMS) deposit. Research material (core, documents, etc.), conducted by Exxon ...
Petrogenesis of Archean (2.7 Ga) Mafic Volcanic Assemblages Near Ely, MN
(2019-05)
The Vermilion District in northeastern Minnesota contains one of the classic Neoarchean
Archean granite-greenstone belt terranes in the United States that formed between 2722 Ma to
~2661 Ma. Crustal development during ...
Mineral Chemistries of the Tower Mountain Au Prospect, Ontario
(2018-04)
Hydrothermal fluid systems driven by magmatic activity are some of the most important ore forming processes for many
metallic minerals. This project involves characterization of hydrothermal alteration associated with the ...
Characteristics of Ore and Trace Mineral Assemblages at the Flambeau Volcanogenic Massive Sulfide Deposit, Northwestern Wisconsin
(2018-04)
This study focuses on the trace mineral abundances and mineralogical variations of the ore zone at the Flambeau Cu-Zn-Au volcanogenic massive sulfide (VMS) deposit located in Ladysmith, Wisconsin.
Volcanic Setting of the 1.8-1.9 Ga. Eisenbrey Cu-Zn Deposit, Rusk County, Wisconsin
(2019-05)
The objective of this research is to complete a petrographic and geochemical characterization of the least-altered volcanic rocks hosting the Eisenbrey Cu-Zn deposit in Rusk County, WI. This study builds on previous UWEC ...
Reconstructing Paleoproterozoic Volcanism in Northcentral Wisconsin: Geology of the Lobo Zn-Cu Deposit
(2019-05)
The Lobo Zn-Cu deposit in northwestern WI, USA, is one of several volcanogenic massive sulfide (VMS) deposits in the state. This deposit has never been mined; therefore, further studies can only be conducted by examining ...
Origin and Evolution of the Sulfide-Rich, Mafic Igneous Intrusion at Eagle Mine, Upper Peninsula, MI
(2019-05)
The Eagle Mine of the Upper Peninsula, Michigan is host to a productive
copper-nickel, sulfide-rich ore deposit that is hosted within the Yellow Dog
Intrusion, a mafic intrusive igneous rock. The origin of the ore and ...
Comparing Paleoproterozoic Felsic Volcanic Centers Across Wisconsin : Implications for Tectonic History and Sulfide Mineralization
(2020-04)
The rocks containing the Crandon deposit are part of the Pembine-Wausau Terrain and formed ~1.85 billion years ago. These formed in a bark-arc setting as part of the Penokean Orogeny. Arc-derived sediments eventually covered ...
