Geoquímica del estroncio en los yesos messinienses de la cuenca de San Miguel de Salinas (Alicante)

Abstract

The Sr contents in the selenitic gypsum deposit of the San Miguel de Salinas basin (Alicante, SE Spain) are related to the sedim entary facies, that is to say, to the p etrological characteristics of the gypsum layers and their paleogeographical position in the basin. The selenitic gypsum facies corresponding to more central areas of the basin form thick beds and show relatively lo w and homogeneous contents. The selenitic gypsum facies corresponding to more marginal zones form thin beds and show higher and more disperse Sr contents.
