Climate and tectonically controlled river style changes on the Sajó-Hernád alluvial fan (Hungary)

Abstract

AbstractBased on geomorphological field investigations, sediment analysis, radiocarbon and palynological data, changes in fluvial style have been recognized on one of the most important low-angle fluvial-dominant alluvial fans on the margin of the Great Hungarian Plain (Hungary). Late Pleistocene and Holocene climatic and tectonic controls are reflected partly by meandering and anastomosed channel pattern changes, and partly by erosional step features on the cone that mark erosional and accumulational phases. This work has led to the surface mapping of a ‘horizontal stratigraphy’ as part of a larger research project in the Tisza region.
