Reconnaissance for mercury over geothermal areas of the Imperial Valley, California. [Analysis of samples of soil gas and gas from drill holes]

摘要

Nine samples of soil gas and gas from drill holes were collected over and near two geothermal anomalies in the Imperial Valley, California, to measure the possible presence of mercury. With the instrumentation used, the smallest quantity of mercury that could be detected was 2 nanograms. No mercury was detected in any sample.
