摘要
古水深的确定是长期未解决的难题,同时也是急需解决的问题。化石群分异度的研究为确定古水深提供了一种新方法。本文通过多方面研究,证实了信息函数与优势度两种分异度与水深之间存在着密切的关系,并利用该关系估算出东营盆地沙三晚期的水体深度范围。
The determination of palaeodepth is a difficult and unsolvedproblem. The fossil community diversity can be used to determine palaeodepth. This paper proves that there is a close relation between diversity and water depth in terms of information function and predominance factor. By means of the relation, the range of water-depth at Dongying basin during late Shahejie Ⅲ(Oligocene) is estimated.
