摘要
本文将吐谷鲁群、克孜勒苏群、卡普沙良群、庙沟群、河口群、赤金桥组、新民堡群等及其相当岩层划归下白垩统;将艾里克湖组、东沟组、巴什基奇克组、苏巴什组、金刚泉群、马连沟群、民和组等及其相当岩层划归上白垩统。侏罗、白垩系的分界,以划在喀拉扎组与吐谷鲁群之间,苦水峡组与河口群之间,红水沟群与犬牙沟群之间,万秀群与东河群之间较宜。
According to the stratigraphic paleontological characteristics,the Tugulu,Kizilsu,Ka-pushaliang,Miaogou,Hekou,Xingmingbao,Donghe Groups and Chijingqiao,Wuerta,Dashuigou Formations,the lower part o(?) the Quanyagou Group and their correspoundingstratums are classified to Lower Cretaceous;the Ailikehu,Donggou,Bashijiqik,Kumutag,Subashi,Wulanshaohu,Minghe Formations and the Jinggangquan,Maliangou,the upperQuanyagou Groups and their equivelent stratums are classified to the Upper Creta-ceous.The boundary between the Jurassic and the Cretaceous is suggested to be set be-tween Kalazha Formation and Tugulu Group,Hongshan Formation and Tugulu Group,Shazaohe Group and Miaogou Group,Kushuixia Formation and Hekou Group,Hong-shuigou Group and Quanyagou Group,Wanxiu Group and Donghe Group.
