متن کاملEcomorphology of Kura Berbel (Barbus cyri, De Filippi, 1865) in Sefidrud River Basine
This study was conducted to investigate the relationship between body shape and environmental factors related to a rivarian ecosystem in Kura barbel (Barbus cyri) of the Sefidrud River basin. For this purpose, a number of 285 specimens were sampled from three rivers with different habitat properties including the Taleghan, Totkabon and Kloraz Rivers. The relationship between body shape (extract...
متن کاملThe evolution of a terrace sequence along the Manas River in the northern foreland basin of Tian Shan, China, as inferred from optical dating
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...
متن کاملRiver-response and Terrace Agradation in the Mediterranean Iberian Peninsula during Historical Times
Mediterranean fluvial environments have responded sensitively to past changes in climate, physiographic conditions and human activity. Chronosequences of river terraces and alluvial deposits were established using morphologic, sedimentological and pedologic criteria, Cand Pb-dating techniques, historical data and pottery fragments. The objective of this study addresses the fluvial dynamic of se...
متن کاملSpecial Section: Late Cenozoic Fluvial Deposits
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...
