Abstract: The ?Liuhe ?site, ?located? on ?the? fourth? terrace ?of? the ?Youjiang ?River,? was ?excavated? from? June? to? November,? 2005,? which? was? a? salvage? archeological? project? for? the? anticipated? construction ?of ?the ?Bose-Nanning? Expressway.? The? excavations? exposed ?an ?area ?of ?1000㎡. A? total? of? 72? relics? were? discovered,? including? 2? neoliths,? 69? paleoliths? and? 1? tektite.? The? paleoliths? include? cores(N=4),? flakes(N=5),? tools(N=14)? and? chunks(N=46).? The? tools? appear? with? choppers(N=12) and? picks(N=2).? Lithic ?raw ?materials? of ?the ?industry? were ?exploited ?locally? from? ancient? riverbeds.? Quartzite(53.61%),? breccia(18.82%),? fine? Sandstone(7.37%),? silicolites? (5.80%),? medium? Sandstone(2.90%) ?and? Quartz(1.45%)? were ?utilized ?in? core? reduction? and ?tool? manufacture,? with? Quartzite ?the ?predominant ?type.? Blanks ?for ?tool ?fabrication? are ?pebbles.? Most? of? the ?stone ?artifacts? are? large ?and? middle? in? size,? and? modified? by ?direct ?hammer ?percussion.?The? stone? tool? assemblage? of? the? Liuhe? site? shows? close? association? with? the? lithic? industry? in? Bose.? Geomorphological ?and? chronological ?comparison? with ?other ?sites ?in? Bose ?Basin ?indicates ?that? the? age? of ?the ?paleoliths ?of ?Liuhe? site?s hould? be?close ?to ?the? early? Middle? Pleistocene.?
