| 摘 要： | 通过对晒瓦晚二叠世岩石地层和生物地层的初步研究 ,认为晒瓦晚二叠世地层属于深水相沉积 ,可划分成4段 ;并根据双壳类、腕足类延限和发育特征 ,分别建立了一个双壳类化石带 (Claraia primitiva- H unanopecten exi-lis组合带 )和二个腕足类化石带 (N eochonetes substrophomenoides- Orthothetina ruber组合带 ,Acosarina dorsisulca-ta- Crurithyris speciosa组合带 ) ;在对牙形石、双壳类和腕足类等典型化石的综合研究基础上 ,首次划分出吴家坪阶和长兴阶 ,改变了以往本区晚二叠世年代地层未细分的状况 ,提高了划分对比精度。

| Abstract: | The Late Permian strata of Shaiwa section can be divided into four parts according to lithostratigraphy and biostratigraphy. One bivalve zone ( Claraia primitiva Hunanopecten exilis zone) and two brachiopod zones ( Neochonetes substrophomenoides Orthothetina ruber zone, Acosarina dorsisulcata Crurithyris speciosa zone) were set up; Wuchiapingian and Changhsingian were separated for the first time from this section based on conodonts, bivalves and brachiopods. |
