Abstract (max. 300 words)Although Mexico has reached an important technological development in the exploitation of hydrothermal systems to produce electricity, it is still possible to increase the current installed capacity through the exploration and exploitation of new promising “hidden” (hot dry rock) geothermal systems. In this scientific context, the search for more reliable and efficient geochemical methods for the exploration of these geothermal resources has been defined as the main goal of the CeMIE-Geo research project P09 “Development and Application of New Advanced Methods in Fluid Geochemistry and Hydrothermal Alteration for the Exploration of Geothermal Systems” (Romo-Jones & Kretzschmar, 2017). The presence of heat flow anomalies and the large areas of recent volcanism located in the country (e.g., the Mexican Volcanic Belt, MVB), has encouraged this project to develop and apply non-conventional geochemical methods for identifying hidden geothermal systems with confidence. These methods include the use of the following geochemical tools: (1) The geochemical mapping of soil-gas fluxes (CO2, H2S and CH4) using infrared gas sensors coupled with accumulation chambers, the CO2 flux monitoring station by using an Eddy Covariance system, and soil-radon gas measurements; (2) The geochemistry of trace elements (e.g., Rare Earth Elements and metals) which are present in geothermal fluids and rock-minerals; and (3) The measurement of magnetic susceptibility and other rock-magnetic properties in volcanic rocks to identify hydrothermally altered areas. All these techniques have been calibrated and applied for the exploration of a hidden geothermal system located within the geological Caldera of Acoculco, Puebla (Fig. 1). A general description of the non-conventional geochemical methods, the geological structure of the geothermal system studied, and some preliminary results will be reported in the present work.

*Biography Summary (max.150 words)Dr Perez-Zarate is a CONACyT chair fellowship, researcher at the Institute of Geophysics, Universidad Nacional Autonoma de México (UNAM). He carried out a PhD thesis related to a geochemometric studies on water-rock experiments for the calibration of Na-K geothermometer, which was awarded by two important thesis competitions of Mexico (INEEL-CFE, and UNAM Foundation-CFE). His main research lines are currently related to geothermal energy, water-rock interaction, geochemistry, geochemometrics, and the development of geochemical tools for the geothermal industry. Dr. Perez-Zarate has also expertise on theoretical, experimental and field studies of fluid geochemistry (solutes, gases and isotopes) applied for the exploration and exploitation of geothermal systems.
