Michael L. Zientek, Ph.D
Michael L. Zientek is a research geologist at the Geology, Minerals, Energy, and Geophysics Science Center. He received a PhD degree in geology from Stanford and a BS degree in geology from the University of Texas. Since joining the USGS in 1983, Michael has devoted his career to studying economic geology and mineral resource assessments and specializes in magmatic ore deposits.
Mike is an economic geologist who works at the USGS Spokane Office, Spokane, Washington. He provides expertise in economic geology, assessment methods, and analysis of global, national, and regional datasets needed to plan, conduct and direct research on a broad range of land-use and mineral-resource-related issues.
His recent resource assessment work includes the SaMiRA assessment for the BLM and the USGS Global Mineral Resource Assessment project.
Mike's research interests include the origin of magmatic ore deposits enriched in platinum-group elements, chromium, and nickel. As part of that effort, he organized and coordinated International Geological Correlation Programme Project 336 from 1992 to 1996, conducted topical studies on the Stillwater Complex in Montana and the Duluth Complex, Minnesota, and worked on projects in Albania, Russia, and Indonesia. He was the Scientist-in-Charge of the Spokane Field Office from 1994 to 1998.

AssmusStratabound copper-silver deposits of the Mesoproterozoic Revett Formation, Montana and Idaho, with a section on databases and spatial-data files for the geology and mineral deposits of the Revett Formation
The western Montana copper belt in western Montana and northern Idaho contains several large stratabound copper-silver deposits in fine- to medium-grained quartzite beds of the Revett Formation of the Mesoproterozoic (1,470-1,401 Ma) Belt Supergroup. Production from the deposits at the Troy Mine and lesser production from the Snowstorm Mine has yielded 222,237 tons Cu and 1,657.4 tons Ag. EstimateAuthorsDavid E. Boleneus, Larry M.

Selected geologic maps covering parts of the Northern Rocky Mountains and adjacent areas were converted to raster images and georeferenced (rectified) for use in a geographic information system (GIS). These rectified images were created for the purpose of visually comparing published geologic maps with other geospatial information. However, they cannot be queried or used for spatial analysis thusAuthorsJeremy C. Larsen, Kenneth C. Assmus, J. Douglas Causey, Michael L. ZientekAssessment of metallic mineral resources in the Humboldt River Basin, Northern Nevada, with a section on Platinum-Group-Element (PGE) potential of the Humboldt mafic complex
The Humboldt River Basin is an arid to semiarid, internally drained basin that covers approximately 43,000 km2 in northern Nevada. The basin contains a wide variety of metallic and nonmetallic mineral deposits and occurrences, and, at various times, the area has been one of the Nation's leading or important producers of gold, silver, copper, mercury, and tungsten. Nevada currently (2003) is the thAuthorsAlan R. Wallace, Steve Ludington, Mark J. Mihalasky, Stephen G. Peters, Ted G. Theodore, David A. Ponce, David John, Byron R. Berger, Michael L. Zientek, Gary B. Sidder, Robert A. ZierenbergMineral production and mining trends for selected non-fuel commodities in Idaho and Montana, 1905-2001
Idaho and Montana state mining statistics were obtained from historical mineral production records and compiled into a continuous record from 1905 through 2001. To facilitate comparisons, the mineral production data were normalized by converting the units of measure to metric tons for all included commodities. These standardized statistical data include production rates for principal non-fuel mineAuthorsJeremy C. Larsen, Keith R. Long, Kenneth C. Assmus, Michael L.
