Holocene alluviation in submontane depressions

Abstract

The author describes the characteristic features of alluviation related to various types of depressions and tectonic tendencies in the submontane zones presenting the examples mainly from Himalayan foredeep, Carpathian foredeep, Hungarian Plain and Po Basin. He distinguishes active mountain fronts with active aggradation and mature relief of submontane depression dissected by younger valleys. Special attention is concentrated on the role of climatic fluctuations at the Pleistocene-Holocene transition and in the Holocene. During last two millennia it is observed a very distinct acceleration of deposition controlled by hum an activity, which in many cases turned the trend in the alluviation of submontane depressions
