History of sedimentation of the Nida Gypsum deposits (Middle Miocene, Carpathian Foredeep, southern Poland)

Maciej Bąbel


The Nida Gypsum deposits are the best exposed in Poland part of the Middle Miocene (Badenian) evaporites of the Carpathian foreland basin. These deposits record various shallow water (< 5 m) evaporative environments. The facies sequence in the lower part of evaporites reflects shallowing (up to emersion) and than deepening accompanied with salinity rise up to halite precipitation. The salinity rise was arrested by refreshment promoting subaqueous dissolution of sodium chloride. This event was followed by the second large salinity rise and then final dilution of brine which finished evaporative sedimentation. The described two saline cyclothems are recognizable over large area of Carpathian foreland basin.
