Possible generation and existence of quartz veins at Cisolok Geothermal Area

Abstract

Cisolok area located at Southern West Java shows various geothermal manifestations. The igneous and volcanic rocks forming the main component of lithology in the area contains quartz veins. This indicates the rocks units in the area may have a close relation to the widely known Cikotok Fomation containing valuable minerals. Macroscopic description of Cisolok quartz vein samples show pyrite and possibly other heavy metal minerals in the veins. Geological condition shown close relation of Cikotok Formation having older geological age to dasitic volcanic rocks extrusted in Cisolok geothermal area. Further and detail research of quartz veins in Cisolok geothermal area will provide relationship to the Cikotok Formation, possible generation and component of valuable heavy minerals. This paper discusses the case condition under lithological and stratigraphic analysis of the volcanic and igneous rocks having quartz veins at Cisolok geothermal area.
