Crescentic dune migration and stabilization： Implications for interpreting paleo-dune deposits as paleoenvironmental records

引用

Journal of Geographical sciences 2017年第11期27卷 1341-1358页

作者： XU Zhiwei Joseph A. mason LU Huayu YI shuangwen ZHOU Yali WU Jiang HAN Zhiyong school of Geographic and Oceanographic sciences Nanjing University Nanjing 210023 China Department of Geography University of Wisconsin Madison Wl 53706 USA school of Geography and Tourism Shaanxi Normal University Xi'an 710062 China

Paleo-dune deposits have been widely used as a proxy indicator of past dune ac- tivity, which is further used to reconstruct paleoclimates. However, recent studies have criti- cally examined the reproducibility of dune chronologies and the complexity of paleo-dune deposits as paleoenvironmental records. This paper addresses questions on the paleoenvi- ronmental implications of dune chronostratigraphies that have been raised by those reviews, in the specific case of crescentic dunes, using a case study from the Mu Us dune field, north-central China. The processes of turn-over and stabilization of relatively small crescentic dunes are first investigated by observational evidence. In combination with the analysis of a simplified sand preservation model and stratigraphic records, the effect of dune morphody- namics on sand preservation is demonstrated. It is especially evident that thick, nearly in- stantaneously deposited sand units record dune stabilization near the very end of a dune activity episode, while thin sand units may signal the preservation of sand deposited earlier in episodes of activity. Interpreting the distribution of luminescence ages that indicate sand deposition over time is not as simple as assumed in some previous work. Low frequency of sand ages could indicate an interval of either dune field stabilization or extensive dune activity but poor sand preservation. A peak of sand age frequency likely represents a shift in dune field activity towards stabilization, not a peak of active dune extent, especially if it partially overlaps with an independently identified interval of stabilization （e.g. one recorded by pa- leosols）. The nature and magnitude of these biases in the distribution of sand ages over time are strongly affected by the magnitude of net sand accumulation, which is in turn related to sand supply, transport capacity and sand availability, and ultimately climate change. rela- tively short dune stabilization and turn-over time （101 to 102

A preliminary quantitative reconstruction of precipitation in southern Mu Us sandy land at margin of Asian monsoon-dominated region during late Quaternary

Journal of Geographical sciences 2015年第3期25卷 301-310页

We present the first quantitative estimation of monsoon precipitation during the late glaciaI-Holocene in the sandy land of northern China, based on organic carbon isotopic composition data from a loess-sand sequence at margin of the Mu Us sandy land. We use the relationship between monsoon precipitation and the carbon isotopic composition of modern soils as an analogue, with a minor modification, to reconstruct precipitation back to c. 47 ka ago. The preliminary results indicate that annual monsoon precipitation was high after 8 ka, with an average of 435 mm; and it decreased during 18 and 8 ka with a mean value of 194 mm. The precipitation value of 47-18 ka varied between the two. We compare the recon- structed precipitation with other records and paleoclimatic modeling results, showing that our record agrees with reconstructions of the monsoon precipitation from other sources, even capturing short climatic events such as the Younger Dryas. We suggest that solar irradiance, high-latitude temperature/ice volume and local evaporation have together modified moistures in the sandy land.

近几十年来,北极圈夏季海冰的面积在持续快速下降,同时伴随着海冰的厚度逐渐减薄以及开放海洋面积的扩大。曾有预言,到本世纪中期夏季北极圈海冰可能完全融化。假如北极海冰完全融化,势必给全球气候系统带来严重的后果,比如造成冻土的加速消融。冻土在消融过程中会释放大量温室气体到大气中,进而加剧全球气候的波动,对气候变化起到正反馈,加速全球气候变暖。另外,冻土的消融往往会给全球地形地貌特征带来严重危害,如喀斯特地貌加速退化,海岸侵蚀作用加强,土壤结构和功能逐渐消失等等。因此,建立冻土消融演化历史与北极海冰融化之间的联系有助于我们预测未来极地冻土消融演变趋势。
