| 摘 要： | 江西修水县西北部元古代九岭群大坑组露头较好，各种原生沉积构造及次生变形构造发育．运用地层学、沉积学与构造地质学相结合的方法建立了其地层层序，探讨了其变质变形特征、沉积古地理与构造古地理．根据大坑组的岩石学特征、沉积相及岩石地球化学特征，推测其为活动大陆边缘弧后盆地浊积扇沉积的产物

| Abstract: | dakeng Formation of the Jiuling Group is well outcropped. There are various types of primary sedimentary structures and secondary deformational structures in Dakeng Formation. By using the methods of stratigraphy with sedimentology and structural geology,the stratigraphic sequence of Dakeng Formation is established. Metamorphic and deformational features,sedimentary paleogeography and tectonic setting are discussed in this paper. The formation is considered to be the product of the turbidite fan in the arc-back basin of the active continental margin on the basis of its petrological attributes,sedimentary facies and geochemical characteristics. |
