摘要
通过对盆内109个点砾岩砾石成分、砾径、古流向的系统统计与沉积学研究,确定该红盆历经三期洪积事件,形成8个冲积扇体。其中期为洪积事件鼎盛时期,形成5个冲积扇体,并在其内首次发现恐龙蛋化石。
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.
