摘    要:黄河上游的化隆盆地在第三纪期间为古湖占据.上新世晚期古湖开始缩小,约1.1MaBP时消失,从而导致黄河在化隆盆地的出现.化隆盆地演化资料表明,青藏高原强烈隆起始于上新世中期,以后经多次快速构造抬升,以1.1和0.8MaBP的抬升最为剧烈.

关 键 词:黄河发育,构造隆升,化隆盆地

Abstract:The evolution process of the Hualong Basin,one of fault basins in the upper reaches of the Yellow River .recorded the uplift of Qinghai-Xizang Plateau and development history of the Yellow River. Based on the researches of Cenozoic stratigraphy,Hualong Basin was formed in Paleogene,then a paleolake in this basin was developed in Neogene. The Paleolake began to become smaller since the middle Pliocene and disappeared at about 1. 1Ma BP. The Yellow River appeared in the Basin at 1. 1 Ma BP. The evolution of the Hualong Basin has shown that intense uplift of the Qinghai-Xizang Plateau occurred at about 3. 4 Ma BP of Pliocene, and then many uplift events happeded. Among them, two intense uplift events, happened respectively at about 1. 1 and 0. 8 Ma B P,were clearly recorded in the Hualong Basin.
Keywords:development of the Yellow River  tectonic uplift  Hualong Basin
