“…The age of the top of core WEDP05 is assumed to be modern because the chronology of several profiles and drill cores not far from the location of core WEDP05 indicate a Holocene age for the uppermost sediments (J. Fan et al, 2013;Liu et al, 2014). The age of the bottom of the core is estimated to be approximately 1.68 Ma based on extrapolation of the average sediment accumulation rate in the Brunhes Chron.…”

“…Previous research on the evolution of the Hobq Desert mainly focused on the age of the modern desert landscape (Yan, 2004;S. Li et al, 2007;Fan et al, 2013), and several studies have proposed that human activity over the past several thousand years played an important role in the desertification of the area (Wang, 1991;Yan, 2004). The chronology of several excavated profiles in the desert, with a depth of only several meters, revealed that the active sand dunes in the Hobq Desert had formation ages ranging from the late Pleistocene to the Holocene (J.…”

Reconstructing the Cenozoic environmental history of Hetao Basin, in the northern part of the Ordos Plateau in North China, is important not only for revealing the evolution of the Yellow River, but also for understanding the formation of the Hobq Desert. Here we present the stratigraphic framework of drill core DR01 with length of 2503.18 m, and the results of magnetostratigraphic and ESR dating and multi-proxy analyses of drill core WEDP05 with length of 274.60 m, from the Hetao Basin. The magnetostratigraphic and ESR results indicate that core WEDP05 spans the last ~1.68 Ma. Stratigraphic sequence of core DR01 indicates that the Hetao area was uplifted and eroded during the early Cenozoic, before subsiding to form a sedimentary basin. Subsequently, the basin was a fluvio-lacustrine environment during the Pliocene and then experienced alternating desert and fluvio-lacustrine conditions during the Quaternary. Sedimentary facies and multi environmental-proxy analyses of core WEDP05 indicate that the basin was occupied by a fluvio-lacustrine system during the following intervals: ~1.47-~1.30 Ma, ~1.17-~1.07 Ma, ~0.68-~0.60 Ma and from ~0.47 Ma to the last interglacial; and that a desert environment developed during the lake regression phases of ~1.30-~1.17 Ma, ~1.07-~0.68 Ma and ~0.60-~0.47 Ma. The presence of aeolian sand at the base of core WEDP05 suggests that the origin of the Hobq Desert can be traced back to the early Pleistocene, and resulted from the erosion and transportation of exposed fluvio-lacustrine sediments by near-surface winds associated with the Asian winter monsoon. A large river channel in the Hetao Basin may have existed as early as the Pliocene, which was 3 occupied by the Yellow River when its upper reaches formed by at least ~1.6 Ma. Subsequently, at least since ~1.2 Ma, the Yellow River formed its drainage system around the Hetao Basin and controlled the paleoenvironment evolution of the basin.

“…Fan et al (2013) dated eolian sand dunes in different areas of the Hobq Desert and found that eolian sand deposition started at~19 ka in the northwestern portion of the desert and had expanded to the eastern portion by~9e7 ka. The OSL ages of a Mu Us Desert eolian sand sequence indicate sand dunes were mobilized at 91,~71 and 48e22 ka, but were stabilized at~65 ka in the desert interior (He et al, 2010).…”

“…In the Hobq Desert, at around 2 ka, the present desert landscape started to develop rapidly in the Hobq area. This was also likely triggered by large scale human activity (Fan et al, 2013). Following widespread dune field stability from~8 ka to 2.4 ka in the Mu Us Desert, multiple episodes of sand dune activity occurred after~2.4 ka (Lu et al, 2005).…”

Holocene stratigraphic sequences in the northern Ordos Plateau and its implications for the disappearance of Huoluochaideng ancient city in the Han Dynasty, North China

The Huoluochaideng ancient city, located in the northern Ordos Plateau, once was a prosperous metropolis in Han Dynasty. However, the city suddenly disappeared at 2.0 ka and the reason for the disappearance is still a mystery. In this article, detailed analysis on the Holocene stratigraphic sequences and active tectonics in the area of northern Ordos Plateau are presented to reveal the reasons for the Huoluochaideng ancient city's disappearance. Our results show that the Huoluochaideng ancient cities were filled with the flood deposits and buried on a group scale. The Holocene flood deposits were widely distributed in the ancient city and adjacent areas. The 14 C dating results of the flood deposits demonstrated the ancient city experienced at least three palaeoflood events (~2.05,~1.99, and~1.85 ka) during the Late Holocene, which are consistent with the occurrence time of the most recent palaeoearthquake events (~2.08-1.85 ka) on the Langshan Mountain piedmont fault. Therefore, it is suggested that the palaeoearthquake events and their secondary damages led to the outbreak of extensive floods in the northern Ordos Plateau. After the last flood event (~1.85 ka), the Huoluochaideng ancient city was buried again by the northward moving Kubuqi Desert due to the arid climate and desertification. In summary, the disappearance of Huoluochaideng ancient city is suggested to relate with the great flood events that was triggered by the palaeoearthquake on the Langshan Mountain piedmont fault, such as the levees break of the Yellow River.
