Geothermal manifestations existed in West Java (Cilayu, Papandayan Mountain, Telagabodas, Karaha, Tampomas Mountain), Central Java (Slamet Mountain, Dieng) and East Java (Argopuro Mountain) show a difference in their mineral and geochemical compositions. The petrographic analysis of volcanic rocks from Garut (West Java) are basalt, andesite basaltic and andesite. However, based on SiO2 vs K2O value, those volcanic rocks have wide ranges of fractionated magma resulting basalt - basaltic andesite to dacitic in composition rather than those of Slamet Mountain, Dieng, and Argopuro Mountain areas which have a narrower range of fractionation magma resulting andesite basaltic and andesite in compositions. The volcanic rocks from Garut show tholeiitic affinity and calc-alkaline affinity. The geothermal potential of Java is assumed to be related to the magma fractionation level. Geothermal potential of West Java (Garut) is higher than that of Central Java (Slamet Mountain, Dieng) and East Java (Argopuro Mountain).
