Pre-Tatiary exposures are known to occur in Java at three localities, namely the Jiwo Hills and Luk Ulo area in Central Java and the Ciletuh area, in West Java. The pre-Tertiary rock assemblage in Luk UIo has been regarded as a melange complex.In the Ciletuh area, the plsTertiary rocks are well exposed dong the course of Citisuk riva and its surrounds oonsisting of ultra basic to basic rocks (peridotite, gabbro, pillowed basalt), metamorphic rocks (serpentinite, schist, phyllite, quartzite) and sedimentary rocks (red clay, black shale, greywacke, limestone). These units are tectoniay mixed, and the realtionship between them can not be explained by applying the law of superposition, lateral continuity and faunal assemblage as used in normal deposition.Data at hand strongly suggest that this rock assemblage might be regarded as a melange complex.
