A seven-million-year hornblende mineral record from the central Chinese Loess Plateau
Autor: Tong He, Lianwen Liu, Yang Chen, Xuefen Sheng, Junfeng Ji
Publikováno v: Scientific Reports, Vol 7, Iss 1, Pp 1-8 (2017)
Abstract Previous studies of the late Cenozoic erosion rate have yielded different views—long-term stable rates or a significant increase at climate transitions—leading to uncertainty concerning the hypothesized global erosion rate controlled by

100 k.y. pacing of the East Asian summer monsoon over the past five glacial cycles inferred from land snails

Publikováno v: Geology. 51:179-183
The effects of orbital forcing on the East Asian summer monsoon (EASM) after the mid-Pleistocene transition are controversial. Chinese cave δ18O records only show low-latitude ∼20 k.y. cycles, while pedogenic proxy records from Chinese loess are d

Effect of altitude on the stable carbon and oxygen isotopic compositions of land snails at the margin of the East Asian monsoon
Autor: Chunqian Li, Hongke Peng, Huayu Lu, Min Wu, Ling Luo, Jun Chen, Xuefen Sheng, Hua Shen, Chenglong Li, Junfeng Ji, Rui Bao, Liping Tan, Ling Sun
Publikováno v: Geochimica et Cosmochimica Acta. 273:99-115
The carbon and oxygen isotopic composition of land snail shells (δ13Cshell and δ18Oshell) has been used to reconstruct paleoenvironmental changes worldwide. Adding to the limited calibration information available for the monsoon marginal regions, w

Reliability of shell carbon isotope composition of different land snail species as a climate proxy: A case study in the monsoon region of China
Autor: Rui Bao, H. Henry Teng, Xuefen Sheng, Junfeng Ji
Publikováno v: Geochimica et Cosmochimica Acta. 228:42-61
Carbon isotope compositions of land snail shells (δ13Cshell) are shown to be indicative of local climate conditions. However, it is largely unknown how the responses of δ13Cshell to climatic factors changes amongst different species. In this study,

Glacial–interglacial change in chlorite concentration from the Lingtai section in the Chinese Loess Plateau over the past 1.2 Ma and its possible forcing mechanisms
Autor: Tong He, Junfeng Ji, Lianwen Liu, Jun Chen, Xuefen Sheng, Yang Chen
Publikováno v: Quaternary Research. 89:511-519
High-precision concentrations of chlorite minerals from the Lingtai section in the Chinese Loess Plateau and the surrounding deserts are presented through a mineral liberation analyzer technique. Variations in chlorite concentration over the last 0.5

Plagioclase sub-species in Chinese loess deposits: Implications for dust source migration and past climate change
Autor: Tong He, Yang Chen, Xuefen Sheng, Junfeng Ji, Lianwen Liu
Publikováno v: Quaternary Research. 85:17-24
Plagioclase mineral sub-species in the Lingtai Section in central Chinese Loess Plateau are examined using Mineral Liberation Analyzer techniques, showing that loess and paleosol samples exhibit similar patterns in terms of plagioclase feldspar sub-s
