| 摘 要： | 江西省震旦纪地层发育，分布广泛，大致以广丰一宜丰一线为界，北部称扬子地层区，南部称东南地层区，扬子地层区为浅海相，东南地层区为斜坡相。因区内不同地段的地层发育程度及沉积特征有明显差异，故可进一步划分出6个地层小区：(1)修水地层小区；(2)皖浙赣地层小区；(3)广丰地层小区；(4]赣中南地层小区；(5)北武夷地层小区；(6）南武夷地层小区。文中介绍了各地层小区的划分依据及它们之间存在的差异与联系，并分别介绍了各地层小区的岩石地层单位特征，及其划分与对比，补充了较丰富的微古植物资料；并对江西省震旦纪地层岩相古地理进行了探讨。此外，对洪山组正层理剖面讲行了重新调研。并修订了原洪山组的合义．

| Abstract: | Sinian strata are well developed and widely distributed in Jiangxi,It can be classified into the Yangtze stratium area which belongs to shallow sea facies sedimentary environment at the north sides of the GuangfengYifeng and eastsouthern stratium area which belongs to slope facies sedimentary setting at the south sides of the GuangfengYifeng. Owing to different developed degrees and depositing features of strata in different sections. The strata can be subdivided into six stratum zones which include Xiushui stratum zones, AnhuiZhejiang-Jiangxi stratum zones, Guangfeng stratum zones, centralsouthern Jiangxi stratum zones, northern Wuyi stratum zones and southern Wuyi stratum zones. This paper introduces the classified evidence of every stratum zones and their differences and connections,and indicates the characteristics of lithostratigraphic units and their classification and corrlation in different stratum zones. Meanwhile,the data of rich Microfossil plants are substrantiated,and lithofaciespalaeogeography of Sinian in Jiangxi province is discussed. Positive stratotype section of Hongshan Formation is researched again and the definition of original Hongshan Formation is revised. |
