| 摘 要： | 辽西中生界义县组时代归属问题 ,争论已久 ,归纳起来主要有三种划分方案 :第一 ,隶属于侏罗纪 ;第二 ,隶属于白垩纪 ;第三 ,归属于为侏罗 -白垩纪 ,属跨纪地层。结合多年来各科研院所及生产单位采集的众多同位素年龄资料的分析及野外所见接触关系研究认为 :原义县组中下部层位岩性组合 ,根据其特征 ,需另建立组级岩石单位 ,应归属到上侏罗统 ,广义义县组上部层位一套岩性组合 ,需重新定义 ,时代应归属到下白垩统。

| Abstract: | The age of Yixian Formation of Mesozoic erathem in West Liaoning has been disputed for a long time At present, there are mainly three viewpoints:Jurasic,Cretaceous,or Jurassic Cretaceous Based on a large amount of isotopic data and the stratigraphic contact relationship in field, it is suggested that Mid Lower Yixian F should belong to Upper Jurassic series;but Upper Yixian F should belong to Lower Cretaceous series |
