Abstract

Kamojang geothermal field is located in Garut approximately 42 Km south-east of Bandung city. This area is vapor dominated system and high temperature around 235-250 o C. Geographically, the area is located on a series of active volcanoes, such as: G.Rakutak, G.Gandapura, G.Guntur and G.Masigit. This volcanoes series are Quaternary volcanoes about 0.452 to 1.2 Ma. G.Guntur is the most active volcano compared to the surrounding volcanoes until now. The complex volcanoes around the Kamojang geothermal field as heat source of the geothermal system. The resulting temperature of the magma interacts with the fluid produced alteration rock. Alteration zone in this field are crystobalitemontmorillonite, illite-montmorillonite and chloriteepidote. By doing thermoluminescence analysis on the rock alteration and comparing with temperature mineral and temperature measurements from wells, it can be seen distribution temperature geothermal until now. Based on the analysis this method indicates that the current temperature in Kamojang geothermal field divided into three, that are: old, medium and young. The young temperatures are expected to contribute good heat on the geothermal systems. Identify the current of paleo temperature to temperature it now using petrography, X-ray diffraction and thermoluminescence methods. The results of this analysis are expected to be used as consideration in the area development of Kamojang geothermal field.
