摘　　要：详细描述了白石-苟家飞来峰内甘溪组地层剖面,首次在汶川水磨及崇州九龙沟发现有甘溪组分布,建立了甘溪组的地层层序,讨论了岩性组合特征及基本层序类型,并进行了层序地层初探。发现甘溪组内存在深水相钙质浊积岩及原地埋藏菊石层,为研究古生物。The Ganxi Formation sections are described in detail in the Baishi Goujia Klippe. It is discovered that Ganxi Formation is distributed in Shuimo, Wenchuan County and Jiulonggou, Chongzhou County. Strata sequence of the Ganxi Formation is established in the first time and the lithological associations and basic sequences are also discussed. It is recognized that there are calcareous turbidite and autochthonous plankton ammononites bedding in the Ganxi Formation, which provides view evidence on palaeontology and sedimentary basin.
