槽状交错层理

沉积构造以块状层理、大型槽状交错层理和斜层理为主，见平行层理、波状层理和极少量的水平层理。

Sedimentary structures are mainly massive bedding , large trough cross bedding and oblique bedding with few parallel bedding , wave bedding and horizotal bedding ;

相同河流亚相的河道微相与泛滥平原微相相比，前者的砂岩粒度较粗、分选性较好，发育槽状交错层理等大型层理构造；

In the same subfacies , grain size is larger and sorting is better in the channel sandstones which developed with large-scale cross-beddings such as trough cross-bedding , compared with sandstones in the flood microfacies .

具有大型单斜层理、槽状交错层理和低角度交错层理，底部具冲刷面；

Its sedimentary structure includes large-scale inclined beddings , trough cross-beddings , low-angle cross-beddings as well as an erosional basal surface .

根据其岩性特征和槽的组合分为单岩性槽状交错层理和复合槽状交错层理。

On the basis of the lithologic characters , the trough cross stratification were divided into single lithologic and multiple unit .
