The close-space luminescence dated loess record from SW Junggar Basin indicates persistent aridity during the last glacial-interglacial cycle in lowlands of Central Asia

Spatial Distribution, Material Composition and Provenance of Loess in Xinjiang, China: Progress and Challenges

“…Hence, this article restates the published article data for secondary citations. Basic material data for the Xinjiang loess include minerals [31][32][33], grain size [27,[33][34][35][36][37], major elements [10,38,39], rare earth elements [13,27] (such as Rb/Sr, LREE/HREE, La N /Sm N , La N /Yb N , Gd N /Yb N , etc. ), proximal material contribution ratio [10], etc.…”

“…Samples were measured by an X-ray fluorescence spectrometer produced by Thermo Scientific company of USA to determine the content of major geochemical elements; a standard sample (GSS-8) was added to the experiment for calibration, and the measurement accuracy was ≥95%. Particle size was measured by a Mastersizer 2000 laser particle size analyzer of Malvern UK [27,[33][34][35][36][37]. The dried whole rock samples of known weight and corundum powder with a purity of 99.99% were thoroughly ground and mixed in an agate mortar, and the main mineral content was measured [32] using an X'Pert Pro MPD poly-crystalline X-ray diffractometer (XRD) produced by PANalytical Company of the Netherlands; we used a copper target, Ni filter and super energy array detector with working tube pressure of 40 kV and tube flow of 40 mA [35].…”

“…The loess is widely developed in the Ili Basin. Loess research in the Yili Basin began earlier than in other areas in Xinjiang, and we have achieved rich research achievements in this region [21,22,28,35,41]. In the Ili Basin, loess covers the river terraces of the upper and middle reaches of the Ili River and its tributaries (Kunes, Tekes and Kashi Rivers) and extends across the edge of the deserts [26].…”
