The Jianglang Mountain is situated at the transitional zone of South China fold-system, Jiangshan-Shaoxing deep rip belt and Baoan-Xiakou-Zhangcun rip belt. The formation of the Xiakou basin was a result of the tensioning of the above mentioned two rips in early Cretaceous, afterward, series deposits such as Guantou formation (K1g), Chaochuan formation (K1c) and Fangyan formation (K1f) which belong to Yongkang group, lower Cretaceous phase, were gradually built, whilst the rips occurred to extrude and the basin began to rise in late Cretaceous. Meanwhile, amounts of tension fissures and joints have been produced since Cenozoic, accelerating down-cutting velocity in base rock. Consequently, landform-building activities such as weathering, eroding and collapsing etc. were prevalent as finally to develop the Danxia landform. The main sceneries to apply for world natural relics are relying on unique and unparalleled peak, split valley with vivid stones and reviving of platform. What is more, it is significant to study lithology, stratigraphy and paleo-biology. According to dating for specimen of dolerite vein through the Yongkang group of Mt. Yafeng by K-Ar method, this article revealed the uplift age of red-bed basin to be 77.89±2.6 Ma BP (K2), i.e., late Cretaceous, the first chronological datum of Danxia landform research in China.
