以要路沟上平房-青石岩、上白庙-罗家沟和小郎家沟-三门店剖面为代表的建昌盆地义县组,自下而上分为5段:第一段主要为砂砾岩(要路沟层)；第二段为砂泥岩、页岩夹凝灰岩,其中包括上白庙层含Cypridea(C.)biventricostata-Yumenia luojiagouensis 介形类亚组合带,罗家沟层产介形类Cypridea(C.)luanpingensis-Yumenia unidorsalta-Djungarica camarata亚组…查看全部>>
The Yixian Formation of Jianchang Basin, represented by the Shangpingfang-Qingshiyan, Shangbaimiao-Luojiagou and Xiaolangjiagou-Sanmendian stratigraphic sections in Yaolugou area, may be subdivided into five members. The first member is characterized mainly by sandy conglomerate (Yaolugou layer). The second member is composed of sandy mudstone and shale intercalated with tuff, including the ostracod Cypridea (C.) bwentricostatarYumenia luojiagouensis assembl…查看全部>>
