Geological setting. a Sections of Badenian gypsum of the Borków quarry (after Peryt and Jasionowski 1994) and Babczyn 2 borehole (middle and upper parts, after Peryt and Kasprzyk 1992; lower part is not shown); black arrows show the intercalations of microfossils-bearing clays described by Peryt (2013a) and this paper, respectively; alabastrine gypsum – alabastrine gypsum originated due to recrystallization of fine-grained gypsum precipitated in association with microbial mats (cf. Orti Cabo et al. 1984) and then transported during storms (cf. Kwiatkowski 1972); sabre gypsum – gypsum type composed of curved gypsum crystals resembling sabres which grew upwards and simultaneously curved laterally, thus most crystals are inclined and curved in the same direction (Bąbel 1986); b Simplified palaeogeographic reconstruction of Mediterranean–Paratethys connection during Badenian Salinity Crisis interval (modified after de Leeuw et al. 2010); star marks location of the Babczyn 2 borehole; c Location map of the Babczyn 2 borehole (after Peryt and Kasprzyk 1992) and the sulphate lithofacies of the Polish Carpathian Foredeep (after Kasprzyk 2005 and Bukowski 2011: fig. 10)
