TL;DR: This new evidence indicates that large source areas of aeolian dust and energetic winter monsoon winds to transport the material must have existed in the interior of Asia by the early Miocene epoch, at least 14 million years earlier than previously thought.
Abstract: The initial desertification in the Asian interior is thought to be one of the most prominent climate changes in the Northern Hemisphere during the Cenozoic era1,2,3,4. But the dating of this transition is uncertain, partly because desert sediments are usually scattered, discontinuous and difficult to date. Here we report nearly continuous aeolian deposits covering the interval from 22 to 6.2 million years ago, on the basis of palaeomagnetic measurements and fossil evidence. A total of 231 visually definable aeolian layers occur as brownish loesses interbedded with reddish soils. This new evidence indicates that large source areas of aeolian dust and energetic winter monsoon winds to transport the material must have existed in the interior of Asia by the early Miocene epoch, at least 14 million years earlier than previously thought3,5. Regional tectonic changes and ongoing global cooling are probable causes of these changes in aridity and circulation in Asia.

TL;DR: In this paper, an extension of the stage system of the oxygen isotope signal extended back to the Gauss-Matuyama boundary was proposed, and the earliest loess layers between 2.5 and 2.3 Ma were found in central China.

TL;DR: In this article, the role of magnetic enhancement and dilution in determining soil magnetic properties is investigated for a range of modern soil types, including those of the Chinese Loess Plateau, Tajikistan and the Czech Republic, and the relationship is completely opposite, with susceptibility minima associated with the most developed paleosols.

TL;DR: Paleosols can be classified according to the interplay among deposition, erosion, and the rate of pedogenesis when they formed as mentioned in this paper, which can be used to interpret landscapes of the past by analyzing paleosol-landscape associations at different spatial scales.

TL;DR: In this paper, a largely descriptive classification system that utilizes those pedogenic features that have the highest preservation potential in the rock record is presented. But despite increased interest in paleosols during the past decade, no satisfactory classification is in current use.
Abstract: Despite increased interest in paleosols during the past decade, no satisfactory classification is in current use. Presented here is a largely descriptive classification system that utilizes those pedogenic features that have the highest preservation potential in the rock record. Emphasized in the classification are morphological and mineralogical features that are easily recognizable in the field and through the petrographic microscope. The classification is based on evaluation of the relative prominence in a paleosol of six pedogenic features or processes: organic matter content, horizonation, redox conditions, in situ mineral alteration, illuviation of insoluble minerals/compounds, and accumulation of soluble minerals. The most prominent of these six features/processes provides the key to classifying a paleosol into one of nine orders. Four of the order names are borrowed from Soil Taxonomy (Histosol, Spodosol, Oxisol, Vertisol), whereas the other five order names are presented here for the first time (Calcisol, Gypsisol, Gleysol, Argillisol, Protosol). The orders may be preceded by one or more subordinate modifiers that describe other important features of the paleosol. The classification is relatively easy to apply to the rock record and should enhance communication and aid in the standardization of terminology
