【 摘 要 】

The Halang formation had been exposed continuously in Pangkalan river, Banyumas Basin. Detailed stratigraphic studies by which using measuring section method was performed on Halang formation which found along Pangkalan river. The facies of Halang formation based on sedimentological study can be divided into five facies association, namely with: proximal channel, distal levee, frontal splay 1, crevasse splay, and frontal splay 2. The thickness of distal levees deposit indicates that Halang formation is confirmed as mud rich system turbidities. Fasies association of Halang formation is controlled by several factors. Changes in sediment supply are that one of factor which created a change in fasies association. Sediment supply has changes caused by sea level changes which are resulting of global climatic changes or tectonic factor. Moreover, volcanism process during Late Miocene leads the sediment supply changes.
