Daftar Isi:
- The Rajabasa is one of volcano strato with level of activity type B which located in Province Lampung. Existence of fluid geothermal in north caster (Sukamandi and Kecapi), south caster (Kunjir and coast Wartawan) and south-east caster (Simpur) be form of temperature dissociation energy of diatomic pickings coming from within the mount body. The geothermal fluid comes from a source interpreted as magma chamber. Resistivity methods with configuration schlumberger done to interpret lithology of rock around district manisfestation "Belerang Kering" (Sukamandi). Based on result of analysis obtained layer controlling fluid flow geothermal is high porosity rock layer so that loaded by fluid geothermal. The sandstone layer lays in various depth of 3-14 meter from surface. Besides lithology rock also occupied by clay-tuff, gravel, and volcano deposit as top soil. while below sandstone layer there is rock layer which more compact (andesitic-basaltic) as basement rock
