Description
Onlap and downlap patterns, which are shown in the depositional model of sequence stratigraphy by HAQ et al. (1987), were firstly found out in the exposed forearc basin-fill succession of the Plio-Pleistocene Kakegawa Group, Japan. The onlap-downlap patterns can be detected by the tracing of intercalated pyroclastic layers which have the same meaning as the synchronous reflection lines in seismic section. A depositional sequence recognized by the stacking patterns and unconformities in the Kakegawa Group might be produced by a global eustatic sea-level change from ca. 3.4Ma to 1.0Ma.
