Dolomías primarias de ambiente lacustre salino: Mioceno de la Cuenca de Madrid

The study focuses on dolomite carbonates that occur in a Miocene evaporitic succession, the Christmas tree gypsum unit. This unit outcrops in the eastern part of the Madrid Basin and it was deposited in a mudflatsaline lake complex during the Lower Miocene. Three types of dolostone facies have been...

description The study focuses on dolomite carbonates that occur in a Miocene evaporitic succession, the Christmas tree gypsum unit.
