| Abstract: | Huixingshao formation belonged to Middle Silurian,the sedimentary environment of the above dozens of meters quartz sandstone is studied few.By the petrological characteristics and sediment grain size of upper sandstone of Huixingshao formation in Heshui profile,combine with other sedimentary structure,two sedimentary cycle sequences of nearshore and foreshore of beach sub environment are identified. |
