Assessing parent material uniformity of a red and black soil complex in the landscapes

of this study were : 1) to assess Zr- and Ti-bearing grains as minerals resistant to chemical weathering prior to applying Zr and Ti elements in determining parent material uniformity, and 2) to confirm whether pedological processes or a lithologic discontinuity

New geoarchaeological investigations of the valley systems in the Aksum area of northern Ethiopia

Recent geoarchaeological investigations of the valley systems to the north and northeast of Aksum have revealed indications of a relatively recent alluvial sequence, probably within the last millennium. The implication is that both during and prior

Modelling long-term summer and winter balances and the climate sensitivity of Storbreen, Norway

Measurements of winter balance (bw) and summer balance (bs) have been carried out at Storbreen since 1949. Here, the AA. apply a simple mass balance model to study the climate sensitivity and to reconstruct the mass balance series prior to 1949

Late Holocene land use at Orstad, Jaeren, southwestern Norway, evidence from pollen analysis and soil micromorphology

different soil management practices for this time period. The soils seem to have been cleared by fire, prior to cultivation. Then, new cultivation fields were laid out on higher levels, and seem to have been improved by adding of organic materials, mainly

Formation, uplift and dissection of planation surfaces at passive continental margins - a new approach

that the planation surface is the end-product of Cenozoic denudation even in basement areas and argue that Phanerozoic sediments must have been present prior to denudation. They suggest that other margins with similar morphology may also be characterized by episodic

A review of Ts/VI remote sensing based methods for the retrieval of land surface energy fluxes and soil surface moisture

This paper aims to offer a systematic review of this Ts/VI (surface temperature/vegetation index) methods. Prior to the review, the biophysical meanings and properties encapsulated in the Ts/VI feature space is elucidated, since these represent
