Monitoring the surface deformation over the loess hills could help us understand the dynamics of soil erosion, the extent of anthropogenic impacts, and the mitigation methods for the potential damage to local ecosystems, agricultural production, socioeconomic infrastructure, water quality, and air quality in the Loess Plateau and the surrounding areas. The objectives of this study were to compr...

in this paper, we report an investigation of changes in land use and ecosystem services on loess plateau in northern shaanxi province from 1978 to 2004. we used three landsat tm and/or etm data sets to estimate changes in the size of five land-cover/land-use categories, and we also used previously published value coefficients to estimate changes in the value of ecosystem services delivered by e...

Soils formed in loess are evidence of both relict and buried landscapes developed on Pliocene-to-latest Pleistocene basalt flows of the Cima volcanic field in the eastern Mojave Desert, California. The characteristics of these soils change systematically and as functions of the age and surface morphology of the lava flow. Four distinct phases of soil development are recognized: phase 1 weakly d...

The Neogene eolian deposits in the Chinese Loess Plateau (CLP) are one of the most useful continental deposits for understanding climatic changes. To decipher Late Neogene paleoclimatic changes in the CLP, we present a terrestrial mollusk record spanning the time interval between 7.1 and 3.5 Ma from the western CLP. The results indicate four stages of paleoclimatic evolution: From 7.1 to 6.2 Ma...

Loess deposits of the Eastern Ebro Valley (NE Iberian Peninsula) occupy an area ~2000 km2 mostly on east depression and locally in Móra Basin. We studied 38 samples loess 47 their possible source areas, order to determine location origin materials, based particle size distribution composition heavy minerals. Our results clearly differentiate two depositional basins disconnected by reliefs Pre-C...

The Skellefte mining District is located in northern Sweden and comprises Palaeoproterozoic, metamorphosed, supracrustal rocks and associated intrusive rocks, which are all host to several ore deposits. Modelling was performed in the GoCAD software platform, using structural geology and petrology as well as magnetic, gravity, seismic, electric and electromagnetic geophysical data, in order to p...

This paper summarises the use of digital remotely sensed data for Quaternary deposits mapping in central Sweden. Landsat TM scene of the beginning of May 1985 was applied. Only six groups of quaternary deposits were distinguished. The classification accuracy of the resultant map was about 50 % in average. Comparison was done with the existing map of Quaternary deposits.

[1] The geologic history of Crater Terby is developed through geomorphic and stratigraphic analyses within the regional context of the Hellas basin. Terby exhibits 2-km-thick sequences of layers that consist of repetitive, subhorizontal and laterally continuous beds. The layers are predominantly fine-grained as indicated by their ease of aeolian erosion, although a few consolidated layers weath...
