TLDR
This article determined the source area from which dusts from the last glacial maximum (LGM) section of the Dome C ice core were derived, by comparing their strontium and neodymium isotopic ratios with those of samples from potential source areas.About:

Modeling the atmospheric dust cycle: 1. Design of a soil-derived dust emission scheme
TL;DR: In this article, a soil-derived dust emission scheme was designed to provide an explicit representation of the desert dust sources for the atmospheric transport models dealing with the simulation of the dust cycle.
Journal ArticleDOI
The paleoclimatic record provided by eolian deposition in the deep sea: The geologic history of wind
TL;DR: The most important change in Cenozoic atmospheric circulation was a severalfold reduction in wind intensity that occurred at the time of the Paleocene-Eocene boundary as mentioned in this paper.

TL;DR: In this article, the authors used linked terrestrial biosphere, dust source, and atmospheric transport models to simulate the dust cycle in the atmosphere for current and last glacial maximum (LGM) climates.

TL;DR: The ice-core record of local temperature, dust accumulation and air composition at Vostok station, Antarctica, now extends back to the penultimate glacial period (∼140-200 kyr ago) and the end of the preceding interglacial as discussed by the authors.

Asian provenance of glacial dust (stage 2) in the Greenland Ice Sheet Project 2 Ice Core, Summit, Greenland
Pierre E. Biscaye,Francis E. Grousset,Marie Revel,S. Van der Gaast,G A Zielinski,A Vaars,George Kukla +6 more
TL;DR: In this article, the authors analyzed samples of dust from the Greenland Ice Sheet Project 2 (GISP2) ice core, Summit, Greenland, dated within marine isotope stage 2 (between 23,340 and 26,180 calendar years B.P.) around the time of the coldest, local, last glacial temperatures, to determine their provenance.

A Sm-Nd isotopic study of atmospheric dusts and particulates from major river systems
TL;DR: In this paper, the average ratio of Sm/Nd is about 0.19 in the upper continental crust, and has remained so since the early Archean, thereby precluding the likelihood of major mafic-to-felsic or felsicto-mafic trends in the overall composition of the sedimentary mass through earth history.

Sand deserts during glacial maximum and climatic optimum
TL;DR: In this paper, it was shown that active sand dunes were extensive 18,000 yr ago, whereas they were generally dormant 6,000 yrs ago, thus the former textbook concept of an arid climatic optimum and a pluvially active glacial maximum is reversed.

Strontium isotopes in weathering profiles, deep-sea sediments, and sedimentary rocks
TL;DR: In this paper, it was shown that even the finest fraction of aluminosilicates deposited in the ocean does not equilibrate with marine strontium, even after prolonged contact with sea water and interstitial marine water.

TL;DR: Three ice cores to bedrock from the Dunde ice cap on the north-central Qinghai-Tibetan Plateau of China provide a detailed record of Holocene and Wisconsin-W�rm late glacial stage (LGS) climate changes in the subtropics.
