How the Quaternary climatic change affects present hydrogeological system on the Chinese Loess Plateau : A case study into vertical variation of permeability of the loess–palaeosol sequence

How the Quaternary climatic change affects present hydrogeological system on the Chinese Loess Plateau : A case study into vertical variation of permeability of the loess–palaeosol sequence
Aquifer ; China ; Climatic change ; Hydrogeology ; Loess ; Palaeosol ; Permeability ; Plateau ; Quaternary ; Semi-arid area ; Shaanxi ; Water resources
The results of in situ permeability measurements on the Luochuan Yuan (tableland), as a case study, illustrate that average infiltration rate of loess layers is higher than that of palaeosol layers, and that average time for the loess layers
to reach quasi-steady infiltration is longer than that of palaeosol layers. In addition, loess layers have higher porosity than palaeosols on average, and it is suggested as a major reason why the loess layers have a higher permeability on average
. The difference of permeability between loess and palaeosol layers facilitates the loess units more likely to be aquifers. In this regard, the Quaternary climatic change theory can make a contribution to hydrogeology of the Chinese Loess Plateau, and the regional

Late Quaternary loess and paleosols, Kashmir valley, India in Quaternary of the Karakoram and Himalaya.

Stratigraphically the loess/palaeosol sequences fall into two broad types : a thicker sequence (20 m) containing 10 clearly defined palaeosols| and a thinner sequence (6-10 m) containing 5 or 6 palaeosols. The characteristics of the palaeosols

Morphoscopy and morphometry of quartz grains from loess and buried soil layers

Belorussia ; Cryoturbation ; Geomorphometry ; Loess ; Morphoscopy ; Palaeo-environment ; Palaeosol ; Pleistocene ; Quartz ; Quaternary ; Ukraine ; Wind erosion
A complex method is suggested for the study of surfaces of sand grains. With this method, middle- and late Pleistocene loess-palaeosol sequences of the Russian Plain, Dnieper Basin, were studied. During deposition of loess layers predominantly

Compound soil horizons with mixed calcic and argillic properties - examples from the northern Great Basin, USA

Aeolian features ; Carbonate ; Clay mineral ; Great Basin ; Lacustrine sediment ; Palaeosol ; Pedogenesis ; Soil properties ; Stratigraphy ; United States of America
In this paper, northern Great Basin palaeosols with compound horizons are reconstructed as to their genesis and correlated, aiming at whether the steady influx hypothesis may apply or whether a complex history must be assumed.

Loess towards (geo) tourism - proposed application on loess in Vojvodina region (north Serbia)

Loess-palaeosol sequences preserve the most important continental record of climatic and environmental changes during the Quaternary. Loess-palaeosol sequences could be used as resources for a contemporary trend in sustainable tourism – geotourism

Episodic late Quaternary palaeogully erosion in northern KwaZulu-Natal, South Africa
