Mercury in Soils As An Indicator of Geothermal Activity: Yellowstone National Park, Wyoming
Preliminary results of a study of the distribution of Hg in 1000 soil samples from Yellowstone National Park show anomalous concentrations of Hg in soils from nearly all geothermal areas, but the magnitudes of the Hg anomalies differ significantly from one geothermal area to another. All Hg anomalies detected in Yellowstone are narrow, extend-ing outwards 0.5 km or less from the thermal feature. No continuous Hg anomaly was detected over the Yellowstone caldera or hypothesized magma chamber. The lack of a continuous Hg anomaly over the Yellowstone caldera is attributed to the presence of a thick !ayer of impervious rhyolite over most of Yellowstone.
