Sedimentology of the of Zayandeh-Rood River alluvial Terraces and the sediment source identification
In this research, three alluvial Terraces that are located in pathway of Zayandeh-Rood River are studied. The river starts from Bakhtiayri Zardkoh mountain and after through Esfahan city ends to Gawkhony lake. Age of alluvial terraces is younger in upstream than downstream and the height level of the terraces decrease relative to current river bed toward the downstream. The terraces were sample...
The Tian Shan range lies in the actively deforming part of the India-Asia collision zone. The uplift rate and deformation pattern of the Tian Shan are important for understanding the dynamics of crustal deformation in the region. The river terraces in northern Tian Shan provide key records of past changes in climate and/or regional tectonics. In this study, a terrace sequence along the Manas Ri...
Four major paired terraces and six short local terraces have been identified along the Maumee River valley between the Ohio-Indiana state line and Perrysburg in northwestern Ohio by detailed field mapping and study of gaging-station records, water-well logs, and soils data. From highest to lowest, the paired terraces have been named the Antwerp, Florida, Napoleon, and Grand Rapids terraces. The...
Mapping in the Homs region of Syria has revealed a hitherto unrecognized staircase of at least 12 gravel terraces of the upper Orontes River. The terrace gravels overlie Pliocene lacustrine marl and have been calcareously cemented into conglomerates, sometimes interbedded with cemented fine-grained alluvium. A tentative dating scheme, based on modelling the regional-scale surface uplift that ha...
This paper applies statistical and geostatistical procedures to a soil chronosequence on the Ž . terraces of the Henares River NE Madrid to analyse the spatial distribution of several soil properties and use the contribution of geostatistics to establishing a landscape evolution model of the area. Particle-size distribution, pH, calcium carbonate and organic carbon were analysed. Statistical pr...
