Abstract

The Karangbolong Mountains belong to the zone of Southern Mountains in Java. The former consists of three series rocks, the oldest being the "Old Andesite" Formation composed of andesitic eruptive and intrusive of oligicene to aquitanian age, uncomprotably overlain by the Karangbolong Limestone Member of Tertiary f1-3. Toward the north the upper most limestone beds interlinger with beds of the Marl-tuff Member of Tertiary f3. After this time marine sedimentation in this area came to a halt. Both the Karangbolong Limestone and the Marl-tuff members together form the Karangbolong Marine Formation.
