On the structure of the deep-sea fan of the Danube River

Abstract

On the basis of geoacoustic profiling data three generations have been distinguished within the deep-sea Ian of the Danube River (older than Middle Pleistocene, Middle Pleistocene, Late Pleistocene - Holocene ones). Schematic maps of the sediments thickness are compiled for the two younger generations. The principal Ian structure includes accessory `lenses of sediments, formed by the material sliding along the fan's slopes. The position of the axial trough and levees of the present-day Danube Ian appeared to be inconsisten with those of older fans due to migi ation of the Danube's mouth.
