Eolian environmental changes in the Northern Mongolian Plateau during the past ∼35,000 yr

Vegetation and climate changes during the last 8660 cal. a BP in central Mongolia, based on a high-resolution pollen record from Lake Ugii Nuur

“…a BP could be suggested by the decline of diatom abundance and the disappearance of cold water genus (Cydlotella bodanica) [13] . The Khyaraany and Sharmmar eolian sections in northern Mongolia show sand layers interbedded in paleosols with 14 C ages of 8300 ± 100 and 4070 ± 70 a BP in the Khyaraany section, and 8672 ± 90 and 4780 ± 80 a BP in the Sharmmar section, and the percentages of Pinus pollen from sand layers in the Sharmmar section are relatively low, suggesting a dry mid-Holocene climate [14,15] . Furthermore, the BIOME climatic reconstruction over Eurasia indicated that the summer temperature was at least 1-2℃ higher and the effective moisture was 10% lower than at present in central Mongolia around 6000 14 C a BP [38] .…”

“…But, the Holocene studies of Mongolia are in relatively poor level for its specific physiographic settings and history. That is, existing Holocene palaeo-lake climatic records [6][7][8][9][10][11][12][13][14] and eolian sequences [14,15] are mostly distributed in northern and northwestern Mongolia. Most of them are not only in low resolution but also short of detailed chorological control and sensitivity of climatic proxies [12,14] .…”

“…It should be mentioned here that Walther [16] had investigated the Holocene sediment of Ugii Nuur, the lake this paper focused, but the poor chronology and discontinuity of sediment hampered the high-resolution climatic reconstructions. In addition, contradictions and disputes remain regarding the regional Holocene climate changes, especially in the mid-Holocene [6][7][8][9][10][11][13][14][15] .…”

NDVI-Based Long-Term Vegetation Dynamics and Its Response to Climatic Change in the Mongolian Plateau

“…The Mongolian Plateau is a unique arid and semiarid region in the world, with various political and economic activities affecting its ecosystems [12,13]. The northern part of the plateau is in the Republic of Mongolia, and the southern part is in the Inner Mongolia Autonomous Region of the People's Republic of China [14,15].…”

Spatiotemporal variations of Zr/Rb ratio in three last interglacial paleosol profiles across the Chinese Loess Plateau and its implications for climatic interpretation

“…Thus the initial Zr/Rb may be altered by subsequent weathering or pedogenesis. Secondly, the expansion and retraction of sandy desert area and dynamic evolution of Gobi desert occurred frequently during ancient periods [16,17,31,32] . This implies that the extent and location of source areas and even the weathering intensity of source material might fluctuate frequently.…”
