Diagrammatic presentation of sea/brine level changes at the Zechstein Limestone/Lower Anhydrite boundary along the arbitrary seismic line shown in Fig. 2c. 1 - progradational deposits; 2 - degradational deposits; 3–4 - progradational to aggradational deposits (3–4); 5 - aggradational to retrogradational deposits: 1 – final stage of deposition of microbial deposits of the reef flat environment in Jabłonna 1. 2 - final stage of deposition of microbial deposits of the reef flat environment in Jabłonna 2 and 3; subaerial exposure in Jabłonna 1. 3 – stages (3a-3c) of sea level fall related to evaporative drawdown – subaerial exposure of the Jabłonna Reef and origin of fresh-water diagenesis and anhydrite cementation (possibly related to longer periods of stabilization of sea level during steps in sea level fall). 4 – deposition of microbial deposits in the top layer of the Zechstein Limestone in the basin. 5 – possibly the (beginning of) deposition of carbonate-enriched strata of the Lower Anhydrite (unit B of Dyjaczyński and Peryt 2014)
