黄河上游积石峡沿着全新世的大规模滑坡筑坝，曾被认为与4.20-4.00 ka BP的中国大洪水和中国第一个王朝夏代的建立有关。本文介绍了循化盆地和积石峡的七条沉积剖面。岩石学、沉积学和光释光（OSL）和AMS 14 C测年结果表明，全新世积石峡存在两个独立的堰塞湖，而不是一个堰塞湖。第一个湖与发生在大约1000年的马尔坡滑坡有关。8.30 ka BP。这个湖逐渐变浅，然后消失了约。6.30 ka BP，滑坡坝被黄河缓慢切割。第二次格龙布滑坡发生在约1000年。6.10 ka BP。随后的湖泊也逐渐变浅，然后消失在约。5.60 ka BP时，滑坡坝被黄河冲穿。这两个滑坡及其相关的湖泊都比黄河中下游的大洪水至少早1400年，比夏朝的开始至少早1600年。因此与这些历史事件无关。
The massive Holocene landslide-damming in the Jishixia Gorges along the upper Yellow River was previously suggested to be related to China's Great Flood at 4.20–4.00 ka BP and the initiation of the first dynasty in China: the Xia Dynasty. Here, we present seven sedimentary profiles in the Xunhua Basin and Jishixia Gorges. The lithological, sedimentary and chronological results, including optically stimulated luminescence (OSL) and AMS14C ages, indicate that there were two separate landslide-dammed lakes rather than one during the Holocene in the Jishixia Gorges. The first lake relates to the Maerpo landslide that occurred at ca. 8.30 ka BP. This lake gradually shallowed and then disappeared by ca. 6.30 ka BP as the landslide dam was slowly incised by the Yellow River. The second Gelongbu landslide occurred at ca. 6.10 ka BP. The consequent lake also gradually shallowed and then disappeared at ca. 5.60 ka BP as the landslide dam was cut through by the Yellow River. Both landslides and their associated lakes preceded The Great Flood in the middle-lower Yellow River by at least 1400 years and preceded the beginning of Xia Dynasty by at least 1600 years. The geomorphic events and therefore unrelated to these historical events.
