TERRACES OF THE MOUNTAIN RIVERS – A GENETIC APPROACH
https://doi.org/10.15356/0435-4281-2015-2-3-15
Abstract
Terraces of the mountain rivers are an important source of mineral products and paleogeographic information. To reveal the terraces and give their precise description the genetic approach is suggested. According to such an approach the cycle terraces are the remnants of equilibrious bottom of the river valley. Knowing the regularities of the bottom structure helps to distinguish their important morphologic elements spreading to terraces - the surface of the former high floodplain and over-talweg step or the bed. They both represent intermediate and ending equilibrious profiles of the corresponding erosion cycle and have horizontal cross-sections. Usually they are buried under deposits on the terraces but their connections with certain lithofacies allow to determine their position in the geologic sections. Realization of the genetic approach is expensive but it should paid off due to resulting possibility of the higher accuracy of the river valley development reconstruction.
