Abstract: | Permian coal-bearing strata of Qujiang-Renhua Region of Guangdong can be subdivided into two conodont zones: Neogondolella liangshanensis-N. bitteri Assemglage Zone occurring in the Lungtan Formation and Neogondolella changxtngensis-N. subcarinata subcarinata Assem blage Zone occurring in the Changhsing Formation. The age of the main coal-bearing beds in this region is Wuchiapingian. |
