Evidences of Asian Geothermal Structure

Abstract

The development of geothermal resources requites assessment based on reliable data. The measured temperatures h m geothermal and hot spring explorations as wejl as heat flows are good parameters to delineate anomalous geothermal zones. Mhough the Curie point depth map is always sketchy, a wide compilation and analysis of magnetic data could provide a good reference of geothermal structure of Asia. The lower limit of seismicity expresses an isotherm of about 350?C and the map of seismicity itself could simply give indirect information related with geothermal * potential. I propose an international cooperative study to compile measured temperatures, magnetic data and seismicity in Asia with the purpose of conMbuting to discussions on the Asian regional geothermal potential.
