摘    要:在分析赣东北鹅湖岭组及有关地层的地质特征、地层划分现状及产生分岐的原因的基础上,提出以岩性、岩相为划分依据,将鹅湖岭组与喷发相相对应,将其下界、上界分别置于沉积喷发相与喷发相、喷发相与喷发沉积相的相变界面上。从而将北京地质学院指定的打鼓顶组建组剖面上的"打鼓顶组"并入鹅湖岭组;将赣东北其它地区的鹅湖岭组下界由安山岩层顶界处上移至安山岩层之上灰绿色砂岩层的顶界处,将铅山一上饶一带鹅湖岭组上界下移至原鹅湖岭组上部的底界处。

关 键 词:鹅湖岭组  地层划分  火山岩相  赣东北

A new knowledge of the Ehuling Formation in Northeast Jiangxi
Abstract:This paper deals with the features of the Ehuling Formation and the related strata in Northeast Jiangxi and analyses the present situation of the stratigraphic division of the E- huling Formation and the reason resulting different.Judging from on the features of volcanic facies,the Ehuling Formation should be equivalent to eruption facies.The lower and the up- per limits of the Ehuling Formation should be drawn at the changing face between sediman- tary-eruption facies and eruption facies,and between eruption facies and eruption-sediman- tary facies.With the result that"Daguding Formation"in the standard section of Daguding Formation proposed by Beijing Geological Institute(1959-1961)should belong to Ehuling Formation,the lower limit of Ehuling Formation in the other area should be shifted from the upper limit of andesite layer to the upper limit of grey-green sandstone layer,the upper limit of Ehuling Formation in the Yanshan-Shangrao area should be shifted to the lower lim- it of the upper part of the initial Ehuling Formation.
Keywords:Ehuling Formation  stratigraphic division  volcanic facies  Jiangxi
