Germanium-rich mineralization, northern Mexico.
Many rare metals play a nearly invisible but vital role in modern society. These "high-tech metals," e.g., germanium, indium, gallium, arsenic, cadmium, selenium, tellurium and thallium, often exhibit unusual semiconductor properties, and thus are used for the production of electronic devices, coatings, fiber optics, polymerisation catalysts, and defense applications such as infrared sensors. They share common geochemical and economic features such as: low abundance in the average crust, lack of significant enrichment in ore deposits, low production capacities and high production costs.
The Tres Marias Mine in Chihuahua state, Mexico, has potential to become a germanium producer. The deposit contains two ore zones: a primary zone consisting of zinc and lead sulfides with germanium, and a so-called oxidized zone containing hemimorphite and willemite, some of which is germanium-bearing. My work on understanding the ore genesis and mineralogy of this deposit is being done in collaboration with Dr. Frank Melcher, formerly of the German Federal Institute for Geosciences and Natural Resources (BGR), Hannover, now at the University of Leoben, Austria, and with War Eagle Mining.
Past research interests have included:
- Silicic rocks in the Somoncura region of Argentina: Constraints from the Somoncura Magmatic Belt, Argentina
Extensive silicic magmatism exists in South America that is not directly attributed to subduction and arc formation. The Somoncura Magmatic Belt in northern Patagonia, Argentina, is an example of such an area with an equivocal genesis. It comprises a suite of intrusive and extrusive silicic units with an enigmatic tectonic origin. This project seeks to determine what the petrogenetic relationships and emplacement timings are between intrusive and extrusive units and host rocks of the Central Somoncura Magmatic Belt in the context of widespread Jurassic magmatism in South America.
This NSF-funded work has been carried out with Daniel Gregori, Ernesto Bjerg, and a graduate student at the Universidad Nacional del Sur in Bahia Blanca (Argentina), undergraduate students (Joy Turnbull, Cody Jacobs) at North Dakota State University (Fargo), in cooperation with Clark Johnson and Brian Beard at the Radiogenic Isotope Laboratory at the University of Wisconsin-Madison; Karl Wirth at the Department of Geology at Macalester College (St. Paul, Minnesota); George Gehrels at the University of Arizona; and Jeff Vervoort at Washington State University.
- Can active learning of geologic concepts be promoted using role-playing software? This question was addressed by development of the Geology Explorer, in cooperation with the NDSU Dept. of Computer Science and the World Wide Web Instructional Committee.
This multi-year project to study science learning in authentic, immersive, virtual environments involved 1) simulated environments for teaching science topics, each framed according to a theoretical approach, role-based learning, 2) an innovative, integrated, distributed software platform for developing and hosting virtual environments, 3) empirical studies using an innovative protocol, scenario-based assessment, for measuring student learning in virtual worlds, and 4) a graduate-level summer school course for in-service teachers who were trained to use virtual environments in their classrooms. This work produced a large, controlled study on the impact of the above methods on student learning.
- A project with Dr. Wei Lin of the Department of Civil Engineering at NDSU, and ECS graduate student Joe Super, on developing a TMDL model for the Upper Souris River, ND. The upper portion of the Souris River, from the border with Saskatchewan, Canada to Lake Darling, a total of 43.4 miles, has been on the North Dakota Section 303(d) list for water quality impairments since 1998. This river reach has been identified as "Fully Supporting but Threatened" for aquatic life and recreation purposes. This classification means that water quality and/or river conditions have not met the standards for designated uses on relatively low frequencies, but enough to raise concerns. This project's goals were to study the reach, and document any impairment that may exist.
