1 Fac ulty of Min ing, Ge ol ogy and Pe tro leum En gi neer ing, Uni ver sity of Zagreb, Pierottijeva 6, Zagreb, Croatia Mt. Medvednica is an inselberg in NW Croatia, which lies at the in ter sec tion be tween the Southeastern Alps, Northwestern Dinarides and Tisza Mega-Unit of the Pannonian Ba sin. Due to the Pliocene-Quaternary N-S di rected short en ing, Mt. Medvednica ex pe ri enced 1500-2000 m of dif fer en tial up lift and now ex poses pre-Neo gene and Neo gene tec tonic and stratigraphic units that are sur rounded by Pliocene-Quaternary sed i ments. This pa per eval u ates a set of quan ti ta tive morphometry meth ods used to iden tify tec toni cally ac tive ar eas within this re gion characterized by low-rate ac tive fold ing and fault ing dur ing the Pliocene-Quaternary. Our anal y sis em ployed ex trac tion of hypsometric curves, cal cu la tion of a hypsometric in te gral, asym me try fac tor, and sta tis ti cal pa ram e ters of lon gi tu di nal stream pro files along 36 drain age bas ins de lin eated from a 25 m res o lu tion DEM of Mt. Medvednica area. De spite lithological het er o ge ne ity of the study area, the morphometric pa ram e ters we ob tain are good in di ca tors for dis crim i nat ing tec toni cally ac tive from in ac tive ar eas. We in terpret that the most tec toni cally ac tive ar eas are lo cated at the SW cor ner and in the cen tral part of Mt. Medvednica, where they are likely re lated to the North Medvednica Bound ary Fault, and to the Kašina Fault, re spec tively. The lat ter di vides the range into dis tinct NE and SW mor pho log i cal and struc tural ar eas.

“…5a). Moreover, this rotation also straightens out the Periadriatic Fault and its extension into Hungary (Fodor et al 1998). We consider the Darno Fault, which separates ALcAPA from the bükk Mountains, to represent part of the Periadriatic Fault (schmid et al 2008).…”

“…For the Alpine part of the ALcAPA Mega-Unit we used the restoration by Frisch et al (1998), which we combined with data from burkhard & sommaruga (1998), Fügenschuh et al (1997), Genser & Neubauer (1989), Grasemann & Mancktelow (1993), Gratier et al (1989), Lickorish & Ford (1998), Philippe et al (1996Philippe et al ( ), ratschbacher et al (1991Philippe et al ( ), schmid et al (1996Philippe et al ( ), schön-born (1992Philippe et al ( , 1999, Nussbaum (2000) and stipp et al (2004). Estimates on the magnitude and direction of extension in the eastern (Pannonian basin) part of ALcAPA were mainly adopted from tari (1996), and also from Fodor et al (1998) andszafián et al (1999). In addition, we used the crustal thinning factor map for the Pannonian basin by Lenkey (1999) to estimate the magnitude of extension affecting the ALcAPA and tisza parts of the Pannonian basin.…”

Orogenic Processes in the Alpine Collision Zone

A map-view palinspastic restoration of tectonic units in the Alps, carpathians and Dinarides reveals the plate tectonic configuration before the onset of Miocene to recent deformations. Estimates of shortening and extension from the entire orogenic system allow for a semi-quantitative restoration of translations and rotations of tectonic units during the last 20 Ma. Our restoration yielded the following results: (1) the balaton Fault and its eastern extension along the northern margin of the Mid-Hungarian Fault Zone align with the Periadriatic Fault, a geometry that allows for the eastward lateral extrusion of the Alpine-carpathian-Pannonian (ALcAPA) Mega-Unit. the Mid-Hungarian Fault Zone accommodated simultaneous strike-perpendicular shortening and strike-slip movements, concomitant with strike-parallel extension. (2) the Mid-Hungarian Fault Zone is also the locus of a former plate boundary transforming opposed subduction polarities between Alps (including Western carpathians) and Dinarides. (3) the ALcAPA Mega-Unit was affected by 290 km extension and fits into an area W of present-day budapest in its restored position, while the tisza-Dacia Mega-Unit was affected by up to 180 km extension during its emplacement into the carpathian embayment. the displacement of the Adriatic Plate indenter led to a change in subduction polarity along a transect through the easternmost Alps and to substantial Neogene shortening in the eastern southern Alps and external Dinarides. While we confirm that slab-pull and rollback of oceanic lithosphere subducted beneath the carpathians triggered back-arc extension in the Pannonian basin and much of the concomitant folding and thrusting in the carpathians, we propose that the rotational displacement of this indenter provided a second important driving force for the severe Neogene modifications of the Alpinecarpathian-Dinaridic orogenic system.

“…In this region the rocks are strongly deformed and it is characterized by several faults and broad shear zones [e.g., Fodor et al, 1998]. The present situation results from collision of the Adriatic microplate with the European Plate, involving three large geodynamic systems: the Alps, Dinarides, and IntraCarpathian Basin.…”

Oceanographic and climatic evolution of the Miocene Mediterranean deduced from Nd, Sr, C, and O isotope compositions of marine fossils and sediments

et al. 2008

[1] Isotopic compositions of marine sediments and fossils have been investigated from northern basins of the Mediterranean to help constrain local oceanographic and climatic changes adjacent to the uplifting Alps. Stable C and O isotope compositions of benthic and planktonic foraminifera from the Umbria-Marche region (UMC) have an offset characteristic for their habitats and the changes in composition mimic global changes, suggesting that the regional conditions of climate and the carbon cycle were controlled by global changes. The radiogenic isotope composition of these fossil assemblages allows recognition of three distinct periods. In the first period, from 25 to 19 Ma, high e Nd values and low 87 Sr/ 86 Sr of sediments and fossils support intense tectonism and volcanism, related to the opening of the western Mediterranean. In the second period, from 19 to 13 Ma the 87 Sr/ 86 Sr ratio of Mediterranean (UMC) deviate from the global ocean, which is compatible with rapid uplift of the hinterland and intense influx of Sr from Mesozoic carbonates of the western Apennines. This local control on the seawater was driven by a humid and warm climate and indicates restricted exchange of water with the global ocean. Generally, the e Nd values of the fossils are very similar to those of Indian Ocean water, with brief periods of a decrease in the e Nd values coinciding with volcanic events and maybe sea level variation at 15.2 Ma. In the third period, from 13 to 10 Ma the fossils have 87 Sr/ 86 Sr similar to those of Miocene seawater while their e Nd values change considerably with time. This indicates fluctuating influence of the Atlantic versus the Paratethys and/or locally evolved seawater in the Mediterranean driven by global sea level changes. Other investigated localities near the Alps and from the ODP 900 site are compatible with this oceanographic interpretation. However, in the late early Miocene, enhanced local control, reflecting erosion of old crustal silicate rocks near the Alps, results in higher 87 Sr/ 86 Sr.Citation: Kocsis, L., T.
