%T A NEW PERSPECTIVE OF JAVA CENOZOIC VOLCANIC ARCS

%X SUMMARY  Martodjojo (1984; 2003) reported that a magmatic  arc of Cretaceous to Early Eocene in age was  located in the north of Jakarta and in Java Sea,  whereas during Early Miocene the arc was shifted  to the south of Java Island. These differ to the  further workers (Soeria-Atmadja et al., 1994) who  interpreted that there are two Tertiary magmatic  arcs in Java, i.e. Late Eocene to Early Miocene and  Late Miocene to Pliocene magmatic belts in Java.  The first magmatic belt is related to Paleogene  subduction located along the southern part of Java,  whereas the other one located north of it, is related  to Neogene subduction. The Quaternary volcanic  cones in general are distributed within the Neogene  magmatic belt. Reevaluation to the geologeological  data and some new radiometric ones has given a  new perspective to Java Cenozoic volcanic arcs.  These data suggest that volcanic arcs of Paleogene,  Neogene and Quaternary were superimposed, and  among of them intra-arc basins have developed.  This new idea may have implications to the  exploration strategy of energy and mineral in the  area.  Key words: Java, volcanic arcs, Cenozoic, super  imposed volcanisms, intra-arc basins
