Current Issues of the Hot Spring Distribution Map in Thailand

Abstract

Hot Spring distribution map is part of an accelerated data base system developed in the department of Mineral Resources. Preliminary exploration and chemical analysis have been conducted in the previously known hot spring manifestation areas. Geothermoter, geologic description, chemical analysis and heat flow data will be published in the map.

Geothermal resources in Thailand are classified into low-medium enthalpy. The water contains low concentration of dissolved chemical species and is characterized by high alkali-sodium and bicarbonate. Heat sources anticipate merging from varieties of tectonic phenomena e.g. granitic rocks comprise high concentration of radioactive elements. Active tensional normal faults and relatively shallow cooling intrusive rocks. The first 300kW binary cycle power plant was established in 1989 at the Fang geothermal field. Thermal water released from the power plant is exploited through drying house and cool storage.

Most possibilities for future geothermal utilization in collaborating between private sector and government sector should be cool storage, barn dryer and therapeutically recreation bathing.
