T1 Unidades evaporíticas eocenas de la Zona Surpirenaica Oriental (Área de La Garrotxa)
T1 Eocene evaporite units of the Southeastern Pyrenean Zone (La Garrotxa area)

AB Three Eocene evaporite units are distinguished in La Garrotxa area (Southeastern Pyrenean Zone, NE Spain)on the basis of geological mapping with integrated sedimentological, structural and borehole data. Theseunits were deposited in a foreland basin during Lutetian time: (1) the oldest and thickest one, the BorróEvaporitic Unit, was deposited in both platform setting and slope-basin environments, previously to theturbidite deposition of the Vallfogona Formation, (2) the Beuda Gypsum Unit was deposited overlying theseturbidites, with no differentiated paleogeographical environments, and (3) the youngest and thinnest one,the Besalú Gypsum Unit, was deposited in a siliciclastic platform, just before the change from marine tocontinental conditions in the basin. As a whole, this evaporitic evolution reflects decreasing intensity in thesuccessive salinity crises in the foreland basin in parallel with its progressive filling and loss of marine influence
