摘要
通过1：5万区调，在镇远县竹坪地区发现台江-丹寨小区凯里组，并进行区域性对比研究，发现其凯里组的岩石和生物组合仅相当于南皋凯里组的下部，生物地层对应于Kunmingaspis-Nangaops组合带，但Kaotaiaglobosa峰带和扬子区Kaotaia-Paramecephalus奥佩尔带的共生分子穿插于其中。造成这种生物组合面貌，与其沉积环境的变迁有着密切的关系。
Through 1: 50000 regional geological surveying, Kaili Formation ofTaijiang-Danzhai subregion is found in Zhuping district of Zhenyuan county, Guizhou.The regional correlation shows that lithologic association and biologic assemblage ofthe Kaili For. in the district is corresponding only to the lower part of Kaili For. inNangao district, and biostratigraphy of it is coincident with Kunmingaspis Nangaops Ass. Zone, but some forms of Kaotaia globosa Ac. zone and Kaotaiaporamecephalus Ass. zone of Yangtze Province range into it. The biologic assemblage mentioned above is closely related to sedimentary environment change.
