摘要
广东的二叠纪含煤地层的时代和层位归属一直是个争论的问题,我们重点选择了广东曲(江)仁(化)二叠纪煤田(图1),进行牙形刺的研究。在龙潭组中部余煤段、海相段,上部东煤段和长兴组内均发现了牙形刺,在王成源和王志浩的指导下进行了鉴定,有7属14种和2个未定种,以Neogondolella为主,计10种,并有Anchignathodus,Enantiognathus,Lonchodina,Prioniodella,Neohindeodella,Xaniognathus等,
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.
