| Abstract: | Through statistics and sedimentological study of the gravel composition,grain size and palaeo-flow direction in 109 observation stations within the basin,it has been determined that this red basin has experienced three pluvial phases resulting in eight alluvial fans,of which five were formed in the 2nd phase.Dinosaurian eggs have been for the first time collected from these five fans,assigning them an middle-late Late Cretaceous age. |
