Paleomagnetic measurements have been carried out in continental sediments of Northern ltaly. The loess deposits of Copreno, the loess and paleosols of Cascina Lina and Barlassina, and the lacustrine sediments of Pontida all belong to the Brunhes No

In his 1990 paper (Catena, 17: 175–183), Jan de Ploey proposed a system whereby catchments are viewed as functional units in which geomorphic work results from the combined effects of water erosion and mass movements. His measure of erosional susce

An attempted correlation of selected Brunhes and uppermost Matuyama silt sequences in Eurasia and a comparison of the successive pedogenic features raises the question of climatic evolution during the Middle Pleistocene interglacial stages. In the It

The landslides in the lœss terrain of Gansu Province are a major and recurrent natural hazard in a region with a rapidly rising population which occupies all available space in the landscape. The landslides result from the combination of a climate c

- The thick loessic sequence of central China is a product of the accumulation of aeolian dust over the last 2.5 millions years marked by climatic contrasts in both temperature and precipitation. In the present monsoonal rainfall regime, degradation

Changes occurring in water chemistry and fabric of the loess during water infiltration were experimentally studied using leaching tests on block samples from the Lanzhou area in north central China. Loess series were placed in a device maintaining a

Coming by way of the great desert corridors which run along the northern borders of Tibet, thick aeolian sediments have accumulated over the past 2,4 Ma, alternating with periods of soil development, to form the vast Lœss Plateau of northern China.

In 1985, a programme of research on the sedimentology and diagenesis of the loess and loessic silts of western Europe was initiated jointly by laboratories in Leicester, Meudon, Caen, Milan, Cardiff and Southampton, involving a limited amount of comp

A certain number of clay samples < 2 μ, extracted from several morainic formations in the Dombes (Ain), were examined by means of everal techniques, which could thus be compared : X rays, thermo-balance, determination of C.E.C., of the total and the

Study of fluvio-glacial stepped terraces of Milan Alta Pianura, as well as a succession of soils developed on their alluvium and the loams which cover them, leads to a modification of some of the concepts traditionnally put forward, in Quaternary str
