    江西永新县翻下组四射珊瑚化石的发现及地质意义

    RUGOSE CORALS IN THE FANXIA FORMATION IN WUSHESHAN,YONGXIN COUNTY,JIANGXI

    • 摘要: 作者在江西省永新县乌石山剖面中,原划归晚泥盆世的锡矿山组“翻下段”内,采获大量单体四射珊瑚化石,证明有相当早石炭世早期邵东组 Ceriphyllumelegantum 组合带的存在。此外,在萍乡上株岭还发现了 Cystophretis 及腕足类、植物等化石,这表明孟公坳组也未缺失。因此,可以肯定赣西地区泥盆—石炭系应为整合过渡关系,柳江运动并不存在。同时,产于翻下组的“宁乡式铁矿”亦应属于早石炭世早期,其层位有自西向东逐渐升高的变化特点。

       

      Abstract: This paper introduces a large quantity of solitary rugose corals and a small quantity of brachiopods collected from the strata assigned originally to the Fanxia Mumber of the late Late Devonian Xikuangshan Formation at the secti- on of Wusheshan,Yougxin County,Jiangxi.It has been confirmed that there exists the early F arly Carboniferous Ceriphyllum elegantum assemblage zone. Besides,Cystophrentis,brachiopods and fossil plants were discovered in Shang- shuling,Pingxaing.This indicates that the Mengkongao Formation is laso not absent.Therefore,the contact between the Devonian and the Carboniferous should be conformable in western Jiangxi and the Liugiang movement did not- exist.The age of the Ningxiang-type iron deposit occurring in the Fanxia Formation should be early Early Carboniferous.Its stratigraphichorizon rjses gradually from west to east.
