Basic principles of geomorphological search-and-estimate studies under volcanogenic belt conditions

Abstract

Methods of geomorphological search-and-estimate studies are based on five principles: 1) optimum correspondence between the studies' scale and the tasks to be solved, 2) consistent and combined analysis of topographic, geological and geomorphological maps, aerial and space photoes, 3) combined analysis of topography (including reconstructed and buried ones) and deposits, 4) river valleys evolution in assumed to represent rhythmical fluctuations superimposed on a un-directional trend, 5) epochs of placers formation are thought to correspond to certain stages in the Cenozoic topography evolution.
