Geochemistry and Dynamics of the Yellowstone National Park Hydrothermal System!
The magmatic-hydrothermal system at Yellowstone National Park is unique among presently active systems in regard to its unparalleled geysers, tectonic environment, and magnitude of caldera-forming volcanic activity. However, over geologic time, systems like Yellowstone have been common and appear to have been responsible for the formation of many important basc-metal and precious-mctal ore depo...
متن کاملMicrobiology in Yellowstone National Park.
Yellowstone National Park plays host to numerous microbiological research projects — officially 23, according to the 1996 Investigators' Annual Reports. However, once categories such as aquatic ecology, the study of brucellosis and other wildlife diseases, environmental education, geochemistry and geothermal systems, and vegetation are included, the total came to at least 35 in 1996. Research p...
متن کاملAquificales in Yellowstone National Park
Aquificales are metabolically versatile chemolithoautotrophic thermophilic bacteria. This group is widespread in both deep-sea and terrestrial hydrothermal systems. In Yellowstone National Park, they were first described in early descriptions of the biology of the park, and later captured the attention of many microbiologists including Brock, Stahl, Pace, and others. There are four genera curre...
متن کاملDiscovery of the astatine, radon, francium, and radium isotopes
Currently, thirty-nine astatine, thirty-nine radon,??? isotopes have so far been observed; the discovery of these isotopes is discussed. For each isotope a brief summary of the first refereed publication, including the production and identification method, is presented. ∗Corresponding author. Email address: [email protected] (M.

متن کاملTemporal and Seasonal Variations of the Hot Spring Basin Hydrothermal System, Yellowstone National Park, USA
Monitoring Yellowstone National Park’s hydrothermal systems and establishing hydrothermal baselines are the main goals of an ongoing collaborative effort between Yellowstone National Park’s Geology program and Utah State University’s Remote Sensing Services Laboratory. During the first years of this research effort, improvements were made in image acquisition, processing and calibration. In 200...
