Trace Elements in Quartz, Rutile, and Zircon
Quartz is an ubiquitous mineral that forms in all geologic environments including diagenetic, metamorphic, plutonic, and volcanic settings. Quartz is relatively unreactive and is likely to preserve its geologic history. Trace elements in quartz offer clues to formation temperatures and pressures, fluid chemistry, and tectonic setting. Rutile and zircon are refractory minerals also found in a...
Denver Microbeam Laboratory: Mineral Resources Research Support
The USGS Denver Microbeam Laboratory provides chemical analysis and characterization of rocks, minerals, and environmental samples in support of a wide variety of USGS projects related to mineral resources, including research projects funded by the USGS Mineral Resources Program. The research applications for these projects range from mineral resource research and assessments, to geologic mapping...
Department of Defense Lung Study
Between 2003 and the present, 2.2 million U.S. military personnel have been deployed to Iraq and Afghanistan. These deployers have been variably exposed to desert dusts, smoke from burn pits, and urban particulate matter, and some have developed constrictive bronchiolitis. A study was undertaken to determine what, if any, markers were statistically different among biopsied lung tissue sections...
