The relationship between the geological variation, the F-content of the water and the spatial variation in the occurrence of dental fluorosis in an endemic area
The scope of this study is to represent a detailed idea on the structural situation in Abu Darag area. This goal was achieved by integrating the available seismic data and both geophysical-geological borehole data. This was to identify the area
Data used in this study consist of seismic reflection profiles and bathymetric profiles. They reveal the geological evolution of the Ierissos-Alexandroupolis shelf area of the northern Aegean during the latest sea-level rise. The islands of Thassos
origins : (1) an inherent variability in soils owing to geological and genetic constraints, and (2) an alteration of soil physical and chemical properties by the vegetation.
Some possible mechanistic contraints are put on the problem to distinguish the effects on species evolution from punctuate forces (geological selection pressure generated by buoyancy and tectonic processes) and from near continuous point mutation
Pedogenic processes are active in the footslope and toeslope positions because of the stability of that portion of the landscape. The pedological processes of clay and iron translocation, colluviation and leaching and the geological processes
This paper outlines the geological characteristics of the area, the bioclimatic conditions, badlands evolution and the infiltrability of the Neogene marl regoliths, as well as correlations between rainfall, overland flow and soil erosion. Piping
, the largest glacial cover occurred during the early part of the Upper Pleistocene. A major ice sheet covering the whole of the Qinghai-Xizang Plateau can be ruled out on the basis of geological evidence and climatological theory, although many medium-sized ice
of the instability of inactive fan sediments. The AA. use detailed geological and geomorphological mapping and interpretation to show how faulting and stratigraphic variations have created slump features, subsidence zones, scarpettes and cemented colluvium aprons
topographic and geologic conditions in the basin, and changes in external factors, such as climate and man, on the development in the floodplain are evaluated. - (Author).
