The Pienides are structural units formed almost exclusively of deep-water siliciclastic deposits, Middle Jurassic-Oligocene in age, belonging of an oceanic crust-bearing domain. The Pienides form an elongate belt extending from Western Carpathians to Poiana Botizei (Maramureş, northern Romania), which represents the easternmost outcrop of these units in the Eastern Carpa-thians. Petrographic analyses on sandstones of different nappes combined with sedimentologic studies (depositional systems, palaeocurrents) allow to con-sider the Inner Dacides (forming the pre-Apulian continental margin) the most probable source unit for most of the siliciclastic successions of the Pienides. The present arrangement of the structural units, geophysical and subsurface data and stratigraphic correlations with analogue sequences from Western Carpathians, allow to frame the Pienides in Maramureş in an overall context of trench-slope basin and the related deposits may be considered as a part of an accretionary prism which developed during the whole Palaeogene.
