| Abstract:In the present paper,the sedimentary environments of the Late Lushangfen Stage are discussed through analyzing characteristics of the entomassemblages in Lushangfen Formation.The late stage of Early Cretaceous period was subtropical climate in Jingxi Basin.During the late Lushangfen stage,the flow of river became gradually rapid and the climate became increasingly wet. |
