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 235-250oC. 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.
