摘要
黔南泥盆纪沉积盆地是一个停滞缺氧盆地。本文提出该停滞缺氧盆地的生物相模式,并运用它确定了该盆地沉积时水深和古坡度,解释了某些沉积层序的韵律性变化。
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.
