The East African Rift System transects the anomalously high-elevation Ethiopian and East African plateaux that together form part of the 6,000-km-long African superswell structure. Rifting putatively developed as a result of mantle plume activity that initiated under eastern Africa. The mantle activity has caused topographic uplift that has been connected to African Cenozoic climate change and ...

introduction: soil genesis and development in arid and semi-arid areas are strongly affected by geological formations and geomorphic surfaces. various morphological, physical, and geochemical soil properties at different geomorphic positions are usually attributed to different soil forming factors including parent material and climate. due to variations in climate, geological formations (quater...

The swampy meadows atop the vast Qinghai–Tibet Plateau in West China fall into alpine, pediment, valley, floodplain, terrace, lacustrine, and riverine types according to their hydro-geomorphic properties. They have suffered degradation various levels of severity due climate change external disturbance. In this paper, we studied propensity these degrade from topographic perspective. Evaluated ag...

Up to now, about 140 funerary inscriptions were known from the territory of Neoklaudiopolis/Vezirköprü. In this contribution, 14 more are presented, one which, however, may be attributed Amaseia/Amasya (no. 4). They recorded between 1988 and 1990 by Eckart Olshausen Gerhard Kahl. All them date back Roman Imperial period. One stelae stands out for its unusually high-quality stone carving 8); it ...

In the extreme north of Brazil, in Roraima, there is an important set mafic, volcanic or plutonic rocks, associated with Juro-Cretaceous magmatism, and one most extensive areas Colônia do Taiano region, first agricultural colony Roraima. addition to basalts, many diabases diorites occur, forming patch soils good suitability, cerrado-forest transition. Two soil profiles developed from diabase we...

The main issues about relation between climate and relief in the Romanian geomorphological literature follow three directions of research: the description of Pleistocene glacial and Pleistocene-Holocene periglacial landforms in the Carpathians; the direct analysis of climate?s role in landform development; the integration of separate works and findings in a synthetic morphodynamic system applic...
