On the valleys history in the Southern Sredinny Range of the Kamchatka Peninsula

Abstract

The paper describes terrace alluvium in valleys in the Southern Sredinny Range of Kamchatka, the region featuring denudational-tectonic topography. The fluvial sequence in the terrace series reveals an alteration of cold and warm periods in the alluviation, which permits to correlate the Quaternary climatic fluctuations on Kamchatka with those in West Siberia. Not less than 8 period of river down cutting are distinguished in the evolution of mountain topography, with periods of glacial erosion and glacio-fluvial sedimentation between them.
