| 摘 要： | 建昌盆地义县组可分为两部分：下部以巨厚的沉积层为主，自下而上称为要路沟层、罗家沟层，局部地区沉积层之下有中基性火山岩；上部（罗家沟层之上）为酸性、中酸性火山岩系夹沉积层.罗家沟层与义县-北票地区尖山沟（砖城子）层可进行生物地层学对比.对义县组上部的一件英安岩样品进行40Ar/39Ar年代学研究，获得年龄为120 Ma，应与义县地区义县组顶部火山岩（金刚山层之上）对比.建昌地区义县组顶、底均可与义县地区大致对比.

| Abstract: | The Yixian Formation in the Jianchang basin,Liaoning Province consists of a series of volcanic-sedimentary rocks,which can be divided into two members from bottom to top.The first member is composed mostly of sedimentary rocks,including Yaolugou bed(the lower) and Luojiagou bed(the upper),with intermediate-basic volcanic rocks at the bottom of the member.The second member is mainly acid and intermediate volcanic rocks with clastic rocks.Biostratigraphically,the Luojiagou bed may be correlated to the Jiansha... |
