新疆哈密库莱二叠-三叠纪地层的发现及其意义

Discovery of the Permian-Triassic Strata in the Kulai, Hami, Xinjiang Province and Their Significace

在新疆哈密库莱地区发现了一套二叠-三叠纪地层。其层序自下而上为:二叠系阿其克布拉克群、桃东沟群和下仓房沟群,下三叠统上仓房沟群。在下二叠统阿其克布拉克群,上二叠统桃东沟群的塔尔郎组、下仓房沟群的泉子街组、梧桐沟组和锅底坑组中发现了比较丰富的植物、孢粉、介形虫和瓣鳃类等化石。在下三叠统上仓房沟群的韭莱园组中发现水龙兽化石。根据这些生物化石的一般特征和分布时代,建立了本区二叠纪和早三叠世地层层序。

They are order is as follows: Aqikbulak Group, Taodonggou Group, Lower Cangfanggou Group of the Permian and Upper Cangfanggou Group of the Lower Triassic.
