摘　　要：贵州黔东地区中 -下寒武统凯里组主要由粉砂质泥岩、页岩及灰岩组成 ,富产三叶虫。其中台江八郎乌溜 -曾家岩的凯里组含著名的中寒武世凯里生物群、早寒武世台江生物群 ,2 0 0 1年成为国际中 -下寒武统层型界线候选剖面。对其深入研究具有重大科学和实用意义。就我省黔东地区的凯里组的岩石地层、生物地层、年代地层、沉积环境等进行研究及总结 。The Kaili formation in Eastern Guizhou,China is mainly made up of silty mudstone and shales abundant in trilobites.Kaili formation,located at Wuliu Zengjiayan section of Balang,Taijiang county,as a candidate section of GSSP for Lower Middle Cambrian boundary,is famous for its Middle Cambrian Kaili biota and Lower Cambrian Taijiang biota.This paper conducts a study on the lithostratigraphic,biostratigraphic and chronstratigraphic characteristics and sedimentary environments of Kaili formation,and draws a conclusion that Kaili formation is an important stratigraphic unit because of its scientific and practical significance.
