This study was conducted for the purposes of identifying geothermal zones based on mercury concentrations in the soil.
Mercury concentrations in the soils from the lower east rift zone were measured. Concentrations of 15-1250 ppb were found. Some problems with this study, as far as geothermal exploration goes, were that a wide range of soils exist in the area. Mercury concentrations are dependent on factors such as soil development, ph., ground gasses, and organic content, so linking the measurements with geothermal activity is not straight forward. For the analysis of this data the author attempted to remove some of the non-geothermal factors and it was found that Hg anomalous zones were generally consistent with geothermal reservoir models at the time.
