“…The d 18 O compositions in modern precipitation samples collected at multisites in the Yamdrok Lake basin display marked seasonal patterns with the highest values in spring and lowest in summer Gao et al 2009). The highest concentrations of major soluble ions in snow cover over the southern TP (Wake et al 1993;Kang et al 2008) and the Himalayas (Kang et al 2004, and references therein) generally occur in winter and spring, resulting from dust deposition during the peak activity of the dust storm at that time (Fang et al 2004). The seasonally varying signal of major ionic concentrations has been used solely (Joswiak et al 2010) or as a complementary tool (Kaspari et al 2007) in ice core dating in the TP.…”

A 55-m long ice core, drilled close to bedrock from Mt. Noijin Kangsang on the southern Tibetan Plateau in summer 2007, was annually dated covering the period of 1864-2006 AD. The stable isotope ratios (d 18 O and dD) of the ice core were measured and thereby the deuterium excess (d) was calculated by d = dD -8*d 18 O for the individual ice samples. Results show that the d values of the ice samples were predominantly controlled by the moisture sources. The significant increasing trend of annual mean d values along the ice core is mainly related to the rapid warming of the tropical Indian Ocean, although the tendency is subjected to the modulation by the westernderived moisture. The decreasing Indian monsoon precipitation on the southern Tibetan Plateau, physically linked with the increasing tropical Indian Ocean SST, reduced the share of monsoon precipitation in the annual total accumulation, making an additional contribution to the significant increase of annual mean d in the Noijin Kangsang ice core with high values during the past 143 years.

“…were the main sources for loess deposits in the western Loess Plateau. Fang et al [57] considered that the Tibetan Plateau was an important dust sources for the vicinity of its east and the Far East -Pacific Ocean regions. Wang et al [58] pointed out that lacustrine sediments, shrub dunes, gobi deserts and deteriorated lands were the most potential geogenic dust contributors, but mobile dunes were not.…”

“…Previous studies have suggested that potential dust source regions in inland Asia include a wide range of regions, such as the Gobi and Taklimakan deserts (Liu 1985;Sun et al 2001;Zhang et al 2003), the Qaidam Basin (Bowler et al 1987), the Tibetan Plateau and its eastern areas (Fang et al 2004;Chen et al 2007), and the Gansu Corridor (Derbyshire et al 1998). Most previous studies have focused on eolian material preserved in the depositional regions, e.g., the CLP (Ding et al 2002;Sun 2002;Sun et al 2007) and the North Pacific Ocean (Janecek and Rea 1985;Rea and Leinen 1988;Hovan et al 1989;Rea 1994;Chen et al 1999Chen et al , 2007Nilson and Lehmkuhl 2001;Bailey et al 2011), while less attention has been paid directly to the physical-chemical properties of material from potential source regions.…”

Characterizing magnetic mineral assemblages of surface sediments from major Asian dust sources and implications for the Chinese loess magnetism

Eolian dust plays an important role in the Earth's climate system. Environmental magnetism has been widely used to trace dust variations at different spatial and temporal scales. However, the magnetic properties of sediments from key dust sources have not been well determined. In this study, surface samples from potential dust sources in inner Eastern Asia were systematically investigated. Our results indicate that ferrimagnetic and antiferromagnetic minerals are both present in surface sediments and that they have broad grain size distributions. Ferrimagnetic components are dominated by partially oxidized coarse-grained (pseudo-single domain and multi-domain) lithogenic magnetite particles with minor contributions from pedogenic fine-grained (single domain and superparamagnetic) particles. Antiferromagnetic hematite can be classified into three groups in terms of diffuse reflectance spectroscopy (DRS) band positions (P 560 nm , P 545 nm , and P 535 nm , where numbers indicate the DRS band wavelength for hematite). The first group (P 560 nm ) is the coarse-grained hematite of lithogenic origin and is mostly confined to western China. The P 535 nm group is of pedogenic origin. The P 545 nm group is an intermediate phase that is present both in surface samples from the source regions and in loess. Therefore, the P 545 nm and P 535 nm groups are related to eolian inputs to the Chinese Loess Plateau and pedogenic processes, respectively. In addition, significant differences exist between the magnetic properties of eolian material from sources and depositional regions due to gravitational sorting. These insights provide strong constraints on interpretation of dust signals recorded by the Chinese loess and marine sediments from the North Pacific Ocean.
