Abstract: This paper is based on field investigations since 2000 in the Bubing Basin between Tiandong and Tianyang County, Guangxi Zhuang Autonomous Region, South China. The Bubing Basin is a typical small rifted dissolution basin in South China. The caves are situated in late Paleozoic limestone hills on the margins and inner parts of the basin preserving rich Quaternary deposits and mammalian faunas. Four fluvial terraces werd developed inside this basin. Stone artifacts are collected from the four terraces with ages estimated from early Middle Pleistocene to Early Holocene. These pebble-tool industries contain bifacial technology from the early Paleolithic, and small flake technology in the late Paleolithic. This study provides important evidence for Paleolithic cultural origins and evolution in South China.
