Abstract In the Styrian Basin, early Miocene marine sedimentation of the Karpatian (upper Burdigalian) ended with basin shallowing, marked regression and tectonic movements. The Karpatian sedimentation cycle corresponds to the global 3rd order cycle TB 2.2, followed by the Bur5/Lan1 sea-level fall. This regression was combined with tectonic movements (the Styrian Tectonic Phase), seen in the Styrian Unconformity by an angular discordance at the Wagna and Katzengraben outcrops and also in deep wells. Sediments of the first middle Miocene (Badenian/Langhian) transgression are commonly eroded or reduced in thickness at the basin borders. In the basin center, the bathyal environment continues from the Karpatian to the Badenian. Sediments of the first Badenian transgression have been dated by calcareous nannoplankton as NN4 and correlated by the occurrence of Praeorbulina sicana with the basal Langhian. The 3rd order sequence corresponds to TB 2.3. The erosional phase of the sea-level fall Lan2/Ser1 can only be observed in near-shore facies, followed by transgressive beds within Zone NN5, which represents the second, main Badenian transgression in the Central Paratethys and corresponds to the long global cycle TB 2. The highstand system tract of this cycle is expressed in carbonate build-ups of the Weissenegg Formation. According to the global 3rd order sequences, the youngest sediments of the Retznei section (< 14.39 Ma) overlying the carbonate buildups belong to the falling-stage system tract of TB2, but did not record regression, but instead continuous deepening of the Styrian Basin, indicating strong subsidence during the early middle Miocene._

Die marine Sedimentation während des älteren Miozäns (Karpatium / Oberes Burdigalium) endete im Steirischen Becken mit einer starken, durch tektonische Bewegungen verstärkten Regression. Der Sedimentationszyklus im Karpatium entspricht der globalen Sequenz TB 2.2 und wird durch das Absinken des Meeresspiegels (Bur5/Lan1) begrenzt. Die Kombination der Regression mit den tektonischen Bewegungen („Steirische Tektonische Phase“) ist als Winkeldiskordanz und Sedimentationsunterbrechung („Styrian Unconformity“) sowohl in den Tagesaufschlüssen Wagna und Katzengraben, als auch in Tiefbohrungen ausgebildet. Sedimente der folgenden, ersten Transgression im Badenium/Langhium sind in den Randbereichen des Beckens zumeist erodiert oder nur spärlich erhalten, während im Beckeninneren durchwegs bathyale Sedimente sowohl im Karpatium als auch im Badenium auftreten. Die fol- gende Transgression im Badenium läßt sich anhand des kalkigen Nannoplanktons in die Nn4 Zone stellen und korreliert wegen des Auftretens der planktonischen Foraminifere Praeorbulina sicana mit dem basalen Langhium. Die Sequenz 3. Ordnung entspricht der TB 2.3. Die erosive Phase an der Lan2/Ser1 Grenze ist in den Randbereichen des Beckens als Sedimentationsunterbrechung aus- geprägt, die von der 2. Transgression im Badenium, der Haupttransgression innerhalb der Paratethys, gefolgt wird. Letztere entspricht dem globalem Zyklus TB 2. Karbonate der Weissenegg-Formation kennzeichnen im Steirischen Becken den Höhepunkt die- ser Trangression. Die über den Karbonaten folgenden Siliziklastika müssten entsprechend der Sequenzstratigraphie als zum „falling stage system tract“ gehörend eine Regression anzeigen, sie kennzeichnen aber durch das kontinuierliche Absinken des Meeresbo- dens die tektonisch bedingte Subsidenz des Steirischen Beckens im Laufe des älteren Mittleren Miozäns.______

1. Introduction During the early Miocene, the region of the circum-Mediter- and Helman, 1994) opened the former seaways again by the ranean, including the vast area of the Paratethys, underwent end of the early Miocene, leading to extensive middle Mioce- profound changes. The Mediterranean was cut off from the ne transgressions (Rögl, 1998, 1999). Transgression in the Indian Ocean; the Eastern Paratethys became an isolated Central Paratethys occurred as far as the area of Karpatian basin and the sea regressed from the Alpine Foredeep in the sedimentation (Fig. 1; Kovač et al., 2007), extending towards West and from the Transylvanian Basin, reducing the Central the Transylvanian and Dacian Basins, to the Carpathian Fore- Paratethys marine realm to the Pannonian Basin area and deep, and connected with the Eastern Paratethys, which was the Carpathian Foredeep (e.g. Kovač et al., 2003). Tectonic also again marine (Fig. 1; Hamor & Halmai, 1988).______movements attributed to the Styrian Tectonic Phase (Stille, The Styrian Tectonic Phase of Stille (1924) characterizes tec- 1924), as a consequence of plate movements (e.g. Mazzolki tonic events at the early/middle Miocene boundary; that is, at Alastair M.D. GEMMELL & Christoph SPÖTL the Karpatian/Badenian and Burdi- galian/Langhian boundaries in the Central Paratethys and Mediterrane- an regions, respectively. This phase, as indicated by its name, is defined by the Neogene tectonic history of the Styrian Basin of SE Aus- tria, which forms a segment of the western part of the Intra-Carpathian Pannonian Basin system. Tectonic activity was accompanied by extensive volcanism (Ebner and Sachsen- Figure 1: Central Paratethys: palaeogeographic reconstruction of the Early Badenian main trans- hofer, 1991; Sachsenhofer, 1996)._ gression within nannoplankton zone NN5 (Rögl and Repp, Naturhistorisches Museum Wien).______Palaeoecological as well as tectonic changes characterize the Kar- patian/Badenian boundary interval, with a general increase in were discussed by comparing the Karpatian/Badenian transi- warm-water species (Badenian climatic optimum) and chang- tion in the Styrian Basin and in the Molasse Basin of Lower ing water depths in regional settings (Harzhauser et al., 2003; Austria (Spezzaferri et al., 2002 a,b; Rögl et al., 2005, 2007).

Due to this coincidence, the Badenian in the successions in the investigated sections was made possible Carpathian area of Romania and also in the Transylvanian by an evaluation of calcareous nannoplankton, planktonic and Basin was considered to start with nannoplankton Zone NN5, benthic foraminifera and also mollusc associations (Rögl et al., subzone NN5a, the Geminithella rotula subzone (Marunteanu 2003; Ćorić et al., 2004a,b). As in the Langhian type section, et al., 1999; Chira, 2000). However, in the Mediterranean, the an overlap of the calcareous nannoplankton Zone NN4 and base of the Langhian falls within the calcareous nannofossil Zone NN4 and has historically been identified with the first appearance of Praeor- bulina sicana (Fornaciari and Rio, 1996; Fornaciari et al., 1997). Con- sequently, some authors correlated the lowermost Langhian (calcareous nannofossil Zone NN4) with the Kar- patian instead with the basal Bade- nian (e.g. Andrejeva-Grigorovich et al., 2001).______Work in the Styrian Basin from 2000 to 2006 revealed complex Styrian Tectonic Phase deformation and Badenian transgressions. As a result, it was possible to separate different Badenian transgressive horizons for the first time, especially in the upper part of the Wagna section, and to document what were previously extended gaps in the sedimentation. Figure 2: Styrian Basin: tectonic setting with location of Wagna, Retznei, Katzengraben and the In an initial attempt, these problems investigated deep wells (according to Sachsenhofer, 1996).______The Styrian Basin: a key to the Middle Miocene (Badenian/Langhian) Central Paratethys transgressions

of Lourens et al. (2004a) and new radiometric ages from the Styrian Basin (Handler et al., 2006) are discussed. For a better understanding of the development in deeper parts of the basin and in sections with more continuous sedimentation, some deep wells have been studied in detail (Perbersdorf 1, Petersdorf 1; Fig. 2).______Foraminifera have been deposited with the Micropalaeonto- logical Collection of the Natural History Museum, Vienna, while the calcareous nannoplankton and the Perbersdorf 1 micro- fossils have been placed at the Austrian Geological Survey, Vienna. A number of publications have documented the results produced during the project (Spezzaferri et al., 2001a-c, 2002a-b, 2004; Rögl et al., 2002, 2005, 2006 a-c, 2007; Ćorić et al., 2004a,b; Hohenegger et al., 2005; Lirer et al., 2006). Identical sections and sample splits were used by Latal and Piller (2003) for isotope studies and by Soliman and Piller (2007) for the investigation of dinoflagellates.______

2. Geological setting The Styrian Basin, which is part of the western Pannonian Basin system, has been subdivided by swells into different subbasins. The main structure, the Middle Styrian Swell, separates the Western from the Eastern Styrian Basin (Fig. 2). The basement is formed by the Austroalpine nappe system. Subsidence of the basin, which started during the early Mio- cene, probably during the Ottnangian, was connected with the lateral extrusions of crustal wedges along strike-slip faults towards the Pannonian Basin (Decker and Peresson, 1996; Frisch et al., 2000). A combination of block rotation, subsidence and uplift formed the different subbasins.

Karpatian near-shore deposits. A description of the Wagna The exposed 75 m of Steirischer Schlier shows a cyclic sedimentation of dark-grey, calcareous, silty shales, interbedded by 15-20 cm thick dolomitic limestones (Fig. 5a). In the upper part of the Steirischer Schlier, a channel filling with basement pebbles cuts the layered succession (Fig. 5b). The beds show a dip of about 20° towards 085° E, becoming less in- clined in the upper part. A slight angular disconformity, with a thin pebble layer, separates the shales from overlying sediments. Above this disconformity follow 5 m grey, bioturbated, clayey silts of Karpa- tian age.______Nannofossil assemblages from the Steirischer Schlier are rich and well preserved, dominated by Coc- colithus pelagicus, Reticulofenes- tra minuta and Sphenolithus heteromorphus. The foraminiferal fauna, which has been recrystallized, is dominated by agglutinated species such as Gaudryinopsis beregoviensis, Textularia laevigata, Spi- rorutilus carinatus and Cribrosto- moides. Among calcareous benthic foraminifera, large Globobulimina pupoides and G. pyrula, together with Allomorphina trigona, Chilos- tomella ovoidea and Valvulineria complanata indicate dysoxic bot- tom conditions.

This marks Badenian boundary and the Bur5/Lan1 sequence boundary a distinct facies change, with a clear sedimentary discordance (Rögl et al., 2002; Spezzaferri et al., 2002 a). The nannoflora of Zo- ne NN4 in these sandy silts shows a strong increase in Helicosphaera ampliaperta. Foraminiferal assemblages are corroded and dominated by Ammonia and elphidiids. The first Praeorbulina sicana occurs, as well as abundant small globigerinids.___ The following ca. 2.5 m of grey, bedded sandy limestone (dip 5° towards 015° E) contains a high amount of skeletal debris. In section 3, these beds interfinger laterally with a small patch reef (Wag02/15 to Wag02/16, Fig. 4), different from the succession in the Weissenegg Formation (Figs 5d, e). The following horizon is characterized by bioturbated, greyish, micaceous sandy silts and silty sands, interrupted by a thin concretion layer, and with fragments of thin-shelled bivalves at the base. The first Praeorbuli- na glomerosa occurs on top of the patch reef.______These beds are overlain by ca. 3 m of rhythmically stratified brownish silty sandstone and siltstone layers with erosive bases and with abundant mollusc casts (Fig. 5f). The erosive base of the lowermost sandstone bed (above Wag02/19, Fig. 4) encompasses the NN4/NN5 boundary, thus indicating a distinct sedimentation gap.

Fine- grained calcareous sandstones with corallinacean debris and Planostegi- na, the Aflenz Stone (a well-known building stone of the region), overlie coral patchreefs. Corallinacean limestones and patches of corals form the upper part of the carbonate buildup. The occurrence of Planostegina giganteoformis is characteristic for the Lower Badenian in the Styrian Basin. An erosional surface trunca- tes the limestones, followed by a siliciclastic sequence, reflecting increa- sing water-depths.______

3.3 Katzengraben section near Spielfeld____ A stratigraphic succession, comparable to the Wagna and Retznei sections, but with a more clastic cha- racter, is exposed in the abandoned sand pit at Katzengraben west of Spielfeld (Figs 2, 3c). The >22 m high section consists of silt with fine sand layers and lenses; layers of medium sand are present in the basal section and clean, sometimes concretionary sandstone is characteristic of the upper part (Fig. 8). Co- arse gravels and fine gravel horizons occur within a silt layer exposed from 5.35 to 6.20 m above the present base of the outcrop. At the base of these gravel bearing silts, a layer of reworked Karpatian shale pebbles was also observed. From 11.5 to 11.80 m, a silty fine sand layer with fine gravels contains disper- sed lonestones on its top. Besides very rare mollusc shell fragments in the higher fine sandy part, the Kat- zengraben section is free of macro- fossils.

Hol- zer (1994) correlated the Karpatian shales with the Kreuzkrumpl Forma- tion and the sediments above the angular unconformity with the Weis- senegg Formation. The conglomerate bed in the higher part (ca. 12 m) of the sand succession (Fig. 8) corresponds to another disconformity and a further Badenian transgression, as demonstrated by calcareous nannoplankton and foraminifera. Planktonic species of Praeorbulina and Orbulina were not recorded. The Karpatian/Badenian boundary is marked by the first occurrence of the stratigraphically important shallow benthic foraminiferal species Colo- minella paalzowi and Lingulina costata and the overlying disconformity by the occurrence of Vaginulina legumen and Pseudogaudryina lapugyensis. The calcareous nannoplankton flora is similar to associations in the Wagna section, showing both an assemblage change within Zone NN4 at the Karpatian/Badenian boundary and the NN4/NN5 boundary at the base of the Badenian conglomerate, with the occurrence of H. waltrans. The mass occurrence of the small planktonic foraminiferal genus Cassi- gerinella in both Karpatian and Ba- denian (reworked?) sediments is in- teresting, as this was not observed Table 1: Perbersdorf 1 deep well; lithology and revised biostratigraphy of the deep well in the in the Wagna section.______southern Gnas Subbasin.______The Styrian Basin: a key to the Middle Miocene (Badenian/Langhian) Central Paratethys transgressions assemblages of NN4 were observed between 862.0 m and ry rare Globigerinoides were found down to 800 m.

Based on this and the well-log, the base of the Bade- nian has been placed at 838 m.__ The Karpatian sediments show foraminiferal assemblages similar to the Badenian, with abundant agglutinated species. No sedimentary break or distinct faunal change was observed. The lowermost investigated sample, at 927.8 m, has a well- developed foraminiferal fauna with common Spirorutilus. This indicates sedimentation at water depths greater than those in the sublittoral facies. Coastal or near-shore Karpa- tian sediments are missing. Marine Karpatian sediments were only documented from 838 to 935 m.____ Dark grey to red brown shales with layers of conglomerates and tuffites form the lower part of section, with some traces of lignite. The microfossil content is reduced to silicified stems and tubes, probably of plant roots. This lower part of the section is subdivided into two parts. The upper part (935 – 1335 m) is dominated by conglomerates and dark shales that might be correlatives of limno-fluviatile Ottnangian deposits (the lower Eibiswald Formation of Kollmann, 1965). The lowermost part (1335 – 1470 m), with reddish, greenish and black shales and red brec- cias corresponds to the continental ?Ottnangian Limnic Series. Kapou- nek (1954) reported some fragments of terrestrial gastropods from these shales. The sediments lie unconfor- mably on the metamorphic basement. The core ended at 1477 m, in Palaeozoic phyllites.______-__

Rich microfossil assemblages belonging to the Lagenidae Zone appear in the Lower Badenian, with a first occurrence of Orbulina. Marine Karpatian sandstones, calcareous shales and tuffites were recorded between 1582 m and 1980 m.

The underlying sequence consists of sandstones, conglomerates and shales with some lignite seams. This part of the sequence is considered to be non-marine, and therefore correlated with the limno-fluvial Ottnangian, in contrast to the interpretations of Ebner and Sachsenhofer (1991) and Polesny (2003).

Moreover, Gelati et al. (1992) considered the Langhian stratotype to represent a single depositional sequence, correlated to the 3rd-order cycle 2.3, su- percycle TB2, of the Global Cycle Chart of Haq et al. (1988).______Recently, Lourens et al. (2004a) proposed, but without a formal definition, placing the base of the Langhian, and therefore the early/middle Mio- cene boundary, at the top of chron C5Cn, dated at 15.974 Ma.______At present, the available published data clearly indicate that there is no general agreement for the identification of the base of the Langhian. Moreover, the poorly preserved marine Langhian records prevent a clear identification of the Globigerinoides- Praeorbulina lineage, which is al- ways used to identify the base of the Langhian.______In Appendix 2 of Lourens et al.

By assigning the normal–reverse–normal polarity sequence in the corallinacean limestones topping the section with polarity chrons C5Bn.1n, C5ADr and C5ADn, respectively, the overlying beds, characterized by rhythmically stratified brownish silty sandstones and siltstone layers, must belong to polarity chron C5Bn.1n (Fig. 10).______The results of palaeomagnetic mea- surements in the Hauptstock and Rosenberg sections in the Retznei quarry (Stingl and Scholger 2005) are shown in Fig. 11. In comparison with the lithology and biostratigraphy of the Wagna section (Geröllmergel), both the normal polarity in the Karpa- tian marls beneath the coral limestone must be placed in chron C5Cn.3n

7. Discussion By comparisons with the Mediterranean stratigraphy, the biostratigraphic and palaeomagnetic results have allowed the time ranges of sedimentation gaps to be calculated between the transgressions in the investigated near-shore localities (Figs 10, 12, 13). In the basinwards positioned Wagna clay pit, the time gap between polarity chrones C5Cn.2r and C5Cn.1n, which contains the first Badenian transgression, was ca. 400 ky. The second gap, between C5Br and C5Bn.1n, which includes the second Badenian transgression and the NN4/NN5 boundary, was ca. 600 ky (Figs 10, 12). This gap is much longer at the near-shore Retznei quarry, where polarity chron C5Bn.1n Table 3: Calibration of sequences. Based on the position in palaeomagnetic polarity chrons, global sequences of 3rd order in Haq et (NN5) directly follows C5Cn.3n (NN4), thus marking a time al. (1988) and Hardenbol et al.
