Gas geochemistry from geothermal fumaroles on Akutan Island, Alaska, indicates that geothermal reservoir temperatures could approach 572 °F (300 °C), and probably consists of a brine liquid overlain by a small steam cap. Fluids produced by core holes show evidence of chemical re-equilibration to lower temperatures, with cation geothermometry providing a range from 392-464 °F (200-240 °C). Geochemistry of hot spring fluids shows evidence of equilibrating at still lower temperatures. These data…

Mineralogy at the magma-hydrothermal system interface in andesite volcanoes, New Zealand

Ejecta from phreatomagmatic eruptions of Ruapehu and White Island andesite volcanoes in New Zealand provide insight into the mineralogical reactions that occur when magma invades a vent-hosted

Geological, geochemical, and geophysical survey of the geothermal resources at Hot Springs Bay Valley, Akutan Island, Alaska

An extensive survey was conducted of the geothermal resource potential of Hot Springs Bay Valley on Akutan Island. A topographic base map was constructed, geologic mapping, geophysical and

Historical unrest at large calderas of the world

This is a remarkable reference for researchers interested in volcanic hazards and silicic volcanism. Because of long repose and often obscure shapes and large size calderas are a volcanic type less
