Conference Paper: Geochemical characterization of geothermal systems in the Great Basin: Implications for exploration, exploitation, and environmental issues

Abstract

The objective of this ongoing project is the development of a representative geochemical database for a comprehensive range of elemental and isotopic parameters (i.e., beyond the typical data suite) for a range of geothermal systems in the Great Basin. Development of this database is one of the first steps in understanding the nature of geothermal systems in the Great Basin. Of particular importance in the Great Basin is utilizing that database to classify geothermal systems so that similarities and differences among groups are elucidated and better predictive models assembled. This research is designed to increase utilization of geothermal resources by providing data that will be critical in developing exploration models and exploitation strategies for geothermal energy in the Great Basin. In addition, understanding the geochemical evolution of these various types of systems will provide important insights into the possible contributions of geothermal systems to groundwater chemistry and development of mitigation strategies for attendant environmental issues. Preliminary data suggest that there are differences in the trace element geochemistry of magmatically-driven systems when compared to extensional systems (those that are just driven by elevated geothermal gradients). Once understood in the context of Great Basin geothermal systems, such differences can be utilized to more effectively explore for,

assess the potential of, and develop exploitation strategies for these two types of systems.
