| Abstract: | Predecessors have done quite a lot of investigations and studies on genesis and era of widespread clayey-gravel in Guilin, and advanced many views such as glacial sediment. We prospected two profiles and mapped two artificial exposure profiles during the hydrogeologic reconnaissance on scale of 1:200 000. According to differential thermal, spectral, chemical and spore-pollen analyses of collected samples the sedimentary environment is shown to be damp and hot. In the light of distribution and lithological features of the sediment, and 14C age data this paper consider the sediment to be Middle Pleislocene series mudflow sediment and not to be glacial and outwash sediment. |
