The de vel op ment of a rel a tively small and iso lated part of the Wuchiapingian, Zechstein Wielichowo Reef was pos si ble owing to a pro gres sive sub si dence and fre quent sea level fluc tu a tions. Three biofacies were dis tin guished within this fea ture: (1) the shal low-wa ter and highly en er getic Acanthocladia biofacies, dom i nated by bryo zoans and cri noids, with poorly preserved po ros ity, re duced mainly by cal cite ce men ta tion and com pac tion; (2) the Horridonia biofacies com pris ing nu mer ous brachi o pods pre fer ring a mod er ate depth of wa ter, with com pa ra bly poor po ros ity; and (3) the Fenestella/Kingopora biofacies rich in the most highly vari able fos sils, of the deep est and calm est wa ters, oc cur ring at the top of the sec tion and show ing a sig nif i cant ef fec tive po ros ity, reach ing al most 13%. Among many diagenetic pro cesses al ter ing the reef, sev eral lines of ev i dence sug gest that it was the me te oric diagenesis to en hance its po ros ity most ex ten sively. Since no stromatolites are pres ent, the fi nal sea level drop is in ter preted to be rapid, hence cre at ing con di tions fa vour able for the me te oric dis so lution. Some intraparticle po ros ity, how ever, seems to be of depositional or i gin.

The origin of Upper Permian basinal dolomites in SW Poland: Impact of ascending brines

Pervasive dolomitization of a carbonate sequence is commonly the result of multiphase processes (e.g. Machel, 2004;Warren, 2000, with references therein), and dolomite is in fact a complex suite of early marine to late burial Mg-carbonates (see Mueller et al., 2020).Many researchers indicate that, because of complex chemical alterations, it is difficult to reveal the origin of dolomitization (Özyurt et al., 2019 and Mueller et al., 2020, with references therein). This paper deals with four condensed basinal dolomite sections deposited in the neighbourhood of reefs that formed on one of the intrabasinal highs in the Zechstein Basin in the Brandenburg-Wolsztyn-Pogorzela High (Wolsztyn High in short), SW Poland. The High consists of strongly folded, faulted and eroded Viséan to Namurian flysch deposits capped by a thick cover of Upper Carboniferous-Lower Permian volcanic rocks. This sedimentary-volcanic complex was then strongly fragmented (Kiersnowski et al., 2010). By analogy to the Permian Basin of North America (Saller & Stueber, 2018), one can expect that most of the formation waters previously present in the basin were displaced by highly saline, dense, evaporated seawater also in the Zechstein Basin during the latest Permian. Because of its high density, the seawater remained gravitationally stable in the basin and thus difficult to displace. Thermal history of the Polish Basin suggests the existence of high positive anomalies of heat flow within the distal part of the basin during its initial phase of development, and the highest heat flow during the Late Permian, Triassic and Jurassic in the area northeast of Wrocław (Karnkowski, 1999). This could trigger the intensive brine circulation that led to the development of, among others, dolomitization of basal Zechstein carbonates, in particular in the basinal facies, and the world-class Cu-Ag Zechstein-hosted mineralization that occurs in the Kupferschiefer and adjacent strata in SW Poland. This mineralization is regarded as a result of fluid-rock interaction caused by ascending migration of moderately low-temperature
