摘要
湄潭晚期大致属穆恩之(1979)建立的宁国阶晚期,包括N_6到N_8三个笔石带即Cardiograptus amplus/Glyptograptus nexus 到 Amplexograptus confertus 带的时间范围。相应的岩石地层系统,在湖南吉首以九溪组为代表;湖南古丈及黔东北、黔南的都匀、凯里一带以大湾组上段为代表;贵阳至仁怀一带以湄潭组上段为代表;川西南及滇东以下巧家组为代表。
On the basis of the work done by predecessors,the writers, beginning with the study of the fossils and rock association,divide the age in Guizhou and its adjacent areas into two depositional systems and six facies.
