Polished sections (a-d) and thin sections (e-g) from the uppermost Zechstein Limestone, Jabłonna 3 borehole (the depths in relation to the top of Zechstein Limestone are: a − 0 m, b − 2.2 m, c − 0.5 m, d − 1.5 m, e − 0.6 m, f –2.7 m, g, h − 3.8 m); an – anhydrite, dd – detrital dolomite, ml – microbial limestone. a Zechstein Limestone–Lower Anhydrite boundary (dotted): microbial (thrombolitic) dolomite overlain by dolomite-rich anhydrite with anhydrite nodules; b clasts and microbial laminations steeply inclined within nodular anhydrite; c, d clasts of various size in the anhydrite matrix; e aspect of microbial carbonate (filaments?); f sharp-edge fine clasts of microbial carbonate with isopachous cement; g, h stromatolitic encrustations on and accompanied by detrital deposit; X in (h) indicates the location of (g)
