On the basis of studies of the graptolite succession at the Xiaoyangqiao, Qinggouzi and Muxiantogou sections in the vicinity of Dayangcha village and near Hunjiang City in SW Jilin Province four graptolite zones can be recognized in the 'Yeli Formation': 1. Rhabdinopora parabola Zone, 2. Anisograptus Zone, 3. Psigraptus Zone and 4. Adelograptus-Clonograptus Zone. The correlation of each zone with the equivalent zone and the Cambrian-Ordovician boundary both in China and in other areas of the world are discussed.
