The geology and remarkable thermal activity of Norris Geyser Basin, Yellowstone National Park, Wyoming
- Geological Survey, Reston, VA (USA)
- US National Park Service (US)
Norris Geyser Basin is adjacent to the north rim of the Yellowstone Caldera, one of the largest volcanic features of its type in the world. Hydrothermal activity may have been continuous for {gt}100,000 years B.P. Norris Basin includes the highest erupting geyser of recent water types, colors of organisms and inorganic precipitates, frequent changes in activity and chemistry, and very high subsurface temperatures ({gt}240{degrees}C). Norris Basin is only a part of the Norris-Mammoth Corridor that strikes north from the caldera rim to Mammoth Hot Springs. Norris Basin has a heat flow roughly 10 percent of that of the Yellowstone Caldera and requires an estimated 0.01 km{sup 3} of rhyolitic magma per year-a quantity far greater than the corridor's rate of eruption.
