CO2 Flux Measurements across Portions of the Dixie Valley Geothermal System, Nevada

ABSTRACT - A map of the C02 flux across a newly formed area of plant kill in the NW part of the Dixie Valley geothermal system was constructed to monitor potential growth of a fumarole field. Flux measurements were recorded using a LI-COR infrared analyzer. Sample locations were restricted to areas within and near the dead zone. The data delineate two areas of high C02 flux in different topographic settings. Older fumaroles along the Stillwater range front produce large volumes of C02 at high temperatures. High C02 flux values were also recorded at sites along a series of recently formed ground fractures at the base of the dead zone. The two areas are connected by a zone of partial plant kill and moderate flux on an alluvial fan. Results from this study indicate a close association between the range front fumaroles and the dead zone fractures. To download this resource, please see the link provided.
