| Abstract: | The sedimentary basin of Devonian in Southern Guizhou, South China is euxinic. This paper proposes for the first
time the biofacies model of the euxinic basin. The model may be used to determine the water depth of the basin, the
obliquity of ancient slope, and explain the rythmic change of some sedimentary sequences. |
