| 摘 要： | 上饶县清水乡林山组、罗坳组剖面出露完好、化石丰富、顶底齐全、地层连续，是赣东北新发现的一条下中侏罗统最佳剖面，有１３个化石层位，划分成７个岩性段。野外进行了接触关系、沉积特征、古气候特征资料搜集，室内进行了植物、双壳与叶肢介化石详细鉴定，确认１—５段含Ｐｔｉｌｏ－ｐｈｙｌｕｍ－Ｃｏｎｉｏｐｔｅｒｉｓ植物组合、Ｐｓｅｕｄｏｃａｒｄｉｎｉａ－Ｔｕｔｕｅｌａ双壳组合的含煤地层为林山组，时代为早侏罗世中晚期，６—７段含自流井真叶肢介动物群的杂色砂页岩为罗坳组，时代为中侏罗世。

| Abstract: | The Lower and Middle Jurassic sections located in the Miaoyuan Village of Qingshui Town, Shangrao County, the best Jurassic section discovered in the Northeast Jiangxi, are characterized by the excellent outcrops, abundant fossils, and complete sequence. In the sections 1437.75m thick, were discovered 13 fossil bearing layers and classified into 7 members. The Middle Jurassic Euestheria fauna in Member 6 was of the most significance. The present paper deals, in term of lithostratigraphy and biostratigraphy, with the classification program of the strata, provides the basis for the classification program in terms of sequencestratigraphy, sedimentary formation and palaeoclimate, and identifies Members 1-5 as the Lower Jurassic Linshan Formation ( Ptilophyllum Coniopteris assemblage and Pseudocardinia Tutelella assemblage) and Members 6-7 as the Middle Jurassic Luoao Formation ( Euestheria Fauna). |
