In this particular arrangement a marginal belt exists of bioturbated gypsum, surrounding a central body formed by nodular laminated-facies. This marginal belt is narro win the N W zone and wider in the SE zone. The isotopic compositions (8'30 , 8 34S) of all the studied samples suggest that a concentration gradient occurred in the basin towards the NW area of the central body, where the more saline waters and the depocentre were probably located.spaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/GypsumEvaporitesGeochemistryMioceneCalatayudSpainjournal articleopen access
