| Environmental Evolution of the Jiuquan Basin and Its Relation with the Uplift of the Qilian Mountains since the Quaternary |
| The Qilian Mountains located in the northeastern margin of Tibetan Plateau are products of the tectonic uplift since late Cenozoic, and the deposition of Jiuquan basin kept a record of the uplift process of the Qilian Mountains. During Quaternary, the paleogeography and environmental evolution of Jiuquan basin experienced a prolonged and complicated process, intensely affected by the uplift of Tibetan Plateau. According to such factors as the ice age and glacier change, the characteristics of Quaternary strata, the historical and cultural records and the palynological records in the Q(y1) drill hole at Jiuquan, the authors divided the Quaternary environment at Jiuquan basin into alternate 12 cold periods and 12 warm periods. The relation between the environmental evolution of (Jiu)-quan basin and the uplift of the Qilian Mountains is discussed and a conclusion is drawn that there have been three great climatic shifts in the Jiuquan basin since Quaternary, which occurred respectively after “Series B of Qinghai-Tibetan tectonic movement” (about (2 500) ka B P), after“Kunlong-Huanghe tectonic movement” (about 900 ka B P) and after“Gonghe tectonic movement” (about 150 ka B P). |
