REGIONAL HEAT-FLOW IN WESTERN ANATOLIA USING SILICA TEMPERATURE ESTIMATES FROM THERMAL SPRINGS

Abstract

Regional trends of variation of heat flow in western Anatolia have been outlined using the silica temperature estimator on thermal springs. Silica heat-flow values from 187 springs have been calculated. The data are corrected for local long-term mean annual surface temperature. A mean value of heat flow for the western part of Anatolia of 107 +/- 45 mW m(-2) has been obtained, which is about 60% above the world average.
