Samples of the uppermost Zechstein Limestone of the Jabłonna 1 borehole (the depths in relation to the top of Zechstein Limestone are: a − 0.1 m, b − 0.9 m, c − 1.3 m, d − 2.15 m, e − 3.4 m, f − 3.7 m, g − 4.8 m); an – anhydrite, dd – detrital dolomite, md – microbial dolomite. a-c clasts of microbial carbonates and peritidal laminites within anhydritic and dolomitic matrix (dd – detrital deposit); X in (a) indicates thin section illustrated in Fig. 4d; d steeply inclined pisolitic dolomite; e, f large clasts of microbial carbonate in nodular anhydrite; g microbial encrustations and cement crusts (arrowed) stabilizing detrital deposit consisting of sharp-edge clasts, underlying the brecciated deposits shown in (f)
