摘要
本文应用生物地层带的顺序和定量数据,采用排序法研究了它们的相对秩序,分析了同时事件与生物地层带的交叉、延限、重叠现象。对洞庭盆地不同剖面不同钻井做了地层对比,以确定其地质时代。着重论述了地层轮藻、介形、孢粉的生物地层分带。
In terms of the sequence of biostratigraphic zones and quantitative data,authors have studied their relative order by the regular arrangement method and analysed simultaneous events and the phenomena of biostratigraphic zones:alteration,range overlapping and superposition.Also a comparison has been made among different strta outcropped on the profiles and exposed by drilling so as to decide the ages of them.Particularly this paper stresses the description of the biostratigraphic zones of charophyta,ostracoda and sporopollen and discusses furtherly the relationship between the zones and gas petroleum.
