1 Matej Bel Uni ver sity, De part ment of Ge og ra phy and Ge ol ogy, Fac ulty of Nat u ral Sci ences, Tajovského This study aims at quan ti ta tive ki ne matic anal y sis of fault-slip data and palaeostress re con struc tion of polyphase brit tle struc tures de vel oped in the Manín Unit crop ping out in the Mid dle Váh River Val ley of west ern Slovakia. The Manín Unit neigh bours the Pieniny Klippen Belt that fol lows the bound ary be tween the Paleogene accretionary wedge of the Outer Carpathians and the Cre ta ceous nappe sys tem of the Cen tral West ern Carpathians. Af ter the nappe em place ment dur ing mid-Cre ta ceous times, the Manín Unit was in cor po rated into the Pieniny Klippen Belt and at tained its com plex tec tonic style. Based on ki ne matic anal y sis of meso-scale faults with slick en sides, six (D 1 -D 6 ) brit tle de for ma tion stages have been discerned. The rel a tive suc ces sion of in di vid ual palaeostress states was de rived from field struc tural re la tion ships; their stratigraphic age was es ti mated pri mar ily by com par i son with other pub lished data. Palaeostress anal y sis in the Manín Unit re vealed the ex is tence of six dif fer ent palaeostress fields act ing from the Middle Eocene to the Qua ter nary.

“…The paleogeographical position of the Manín Unit and its relations to the Tatric and the Fatric units or to the Pieniny Klippen-and Peri-Klippen zone are not resolved. The Lower Cretaceous sequence (consisting of Valanginian to Barremian pelagic limestones, covered by Urgonian-type limestones) of the Manín Unit is similar to marginal Central Carpathian units, whereas the Upper Cretaceous sequence is composed of shales unlike in the Central Carpathians, where the sedimentation was broken by strong space reduction due to Alpine folding and nappe formation (Michalík et al 2012(Michalík et al , 2013.…”

“…Firstly, in these units, the input of clasts in platform carbonates indicated that the platform growth was still active during the Late Aptian-Albian, suggesting that the carbonate factory production in the Western Carpathians terminated later than in other Tethyan regions (Boorová 1990;Mišík 1990;Michalík et al 2012). Second, Michalík (1994) and Michalík et al (2012) showed that the carbonate production probably persisted up to the Early Albian in the Manín Unit at Butkov. It remains poorly known whether this late timing of the carbonate demise also applies to other successions in the Western Carpathians.…”

Abstract:The production of platform carbonates of the Manín Unit (Manín Straits, Central Western Carpathians) belonging to the Podhorie and Manín formations and formed by remains of rudists and benthic foraminifers (Urgonian-type carbonates), was previously assumed to terminate during the Aptian. First, we show that these deposits were primarily formed on the upper slope (Podhorie Formation) and in a fore-reef environment (Manín Formation). Second, biostratigraphic data indicate that the shallow-water production persisted up to the Albian, just as it did in another succession of the Manín Unit. The Podhorie Fm contains colomiellids (Colomiella recta, C. mexicana) and calcareous dinoflagellates (Calcisphaerula innominata) that indicate the Albian age. It also contains planktonic foraminifers (Ticinella roberti, Ticinella cf. primula, Ticinella cf. madecassiana, Ticinella cf. praeticinensis) of the Albian Ticinella primula Zone. The Podhorie Formation passes upwards into peri-reefal facies of the Manín Fm where we designate the Malý Manín Member on the basis of rudists shell fragments and redeposited orbitolinids. Microfacies associations share similarities with the Urgonian-type microfacies from Mediterranean Tethys and allow us to restrict the growth and the demise of the carbonate platform. δ 13 C and δ 18 O isotopes change over a broad range of both formations: δ 13C is in the range +1.03 to +4.20 ‰ V-PDB and δ 18O is in the range −0.14 to −5.55 ‰ V-PDB. Although a close correlation between δ 13 C and δ 18 O indicates diagenetic overprint, a long-term increase of δ 13C can indicate a gradual increase in the aragonite production and/or increasing effects of oceanic water masses in the course of the Albian, prior to the final platform drowning. Carbonate platform evolution was connected with submarine slumps and debris flows leading to redeposition and accumulation of carbonate lithoclasts and bioclastic debris on the slope. Our study confirms that the growth of carbonate platforms in the Central Western Carpathians was stopped and the platform collapsed during the Albian, in contrast to the westernmost Tethys. A hardground formed during the Late Albian is overlain by Albian -Cenomanian marls of the Butkov Formation with calcisphaerulid limestones characterized by planktonic foraminifers of the Parathalmanninella appenninica Zone and calcareous dinoflagellates of the Innominata Acme Zone.

Early Cretaceous Equisetites from Slovakia

A new find of terrestrial plant Equisetites cf. lyellii is reported from the Early Cretaceous of Slovakia. It comes from the Mráznica Formation of the Rajec Basin in Fatricum, Zbyňov locality, Rajecké Teplice (Žilina district). The presence of a 53 mm long horsetail axis provides good evidence of terrestrial environments during sedimentation of the studied strata. According to our interpretation, such a plant strongly indicates a moist to wet habitat (even swampy environments) on the presumed dryland from where it was transported. This dryland could represent an isolated unknown small island(s) in the vicinity, or the Vindelician-Bohemian Massif that was active as a dryland for the entire period of time from the Triassic through the Late Cretaceous. However, the exact palaeogeographic position of the Fatricum during the Mesozoic in relation to the Vindelician Landmass is not entirely clear, and such an interpretation needs a bit of caution.
