“…The fault pattern consisting of dextral strike-slip faults, recognized within the Permo-Mesozoic cover, west of the exhumed HCFB, demonstrates the signif- icant role of strike-slip faulting along the western border of the Teisseyre-Tornquist Zone, in the foreland of the Polish part of the Carpathian Orogen in the western Peri-Tethyan domain (e.g., Ziegler 1982Ziegler , 1990aStampfli et al 2001). Horizontal stress was responsible for the formation of strike-slip faults, folds, contractional faults or 'popup structures' and 'flower structures' (e.g., Jaroszewski 1972; Kutek and Głazek 1972;Krzywiec 1999Krzywiec , 2001Krzywiec , 2002Krzywiec , 2007Konon and Mastella 2001;Mastella and Konon 2002;Krzywiec et al 2005;Świdrowska 2007;Zuchiewicz et al 2007;Świdrowska et al 2008;Jarosiński et al 2009;Konon 2015).…”

ABSTRACT:Konon, A., Ostrowski, S., Rybak-Ostrowska, B., Ludwiniak, M., Śmigielski, M., Wyglądała, M., Uroda, J., Kowalczyk, S., Mieszkowski, R. and Kłopotowska, A. 2016. Mnin restraining stepover -evidence of significant Cretaceous-Cenozoic dextral strike-slip faulting along the Teisseyre-Tornquist Zone? Acta Geologica Polonica, 66 (3), 429-449. Warszawa.A newly recognized Mnin restraining stepover is identified in the Permo-Mesozoic cover of the western part of the Late Palaeozoic Holy Cross Mountains Fold Belt (Poland), within a fault pattern consisting of dextral strikeslip faults. The formation of a large contractional structure at the Late Cretaceous -Cenozoic transition displays the significant role of strike-slip faulting along the western border of the Teisseyre-Tornquist Zone, in the foreland of the Polish part of the Carpathian Orogen. Theoretical relationships between the maximum fault offsets/mean step length, as well as between the maximum fault offsets/mean step width allowed the estimation of the values of possible offsets along the Snochowice and Mieczyn faults forming the Mnin stepover. The estimated values suggest displacements of as much as several tens of kilometres. The observed offset along the Tokarnia Fault and theoretical calculations suggest that the strike-slip faults west of the Late Palaeozoic Holy Cross Mountains Fold Belt belong to a large strike-slip fault system.We postulate that the observed significant refraction of the faults forming the anastomosing fault pattern is related also to the interaction of the NW-SE-striking faults formed along the western border of the TeisseyreTornquist Zone and the reactivated WNW-ESE-striking faults belonging to the fault systems of the northern margin of the Tethys Ocean.

“…Subduction of the Vardar ocean (branch of Tethian ocean) beneath the SerboMacedonian-Rhodope Massif has been suggested by Dewey et al (1973) and Boccaletti et al (1974) and later on accepted by most workers (e.g. Aiello et al, 1977;Hsu et al, 1977;Dabovski et al, 1991;Stampfli and Borel, 2004). In contrast, other tectonic interpretations consider the ABTS belt as an extensional structure that originated in an epicontinental rift environment that formed after the Early-Middle Cretaceous collisional deformations as a result of post-collisional collapse and related asthenospheric diapirism (Antonijevic et al, 1974;Popov, 1981, 1987, Popov et al, 2002.…”

The Upper Cretaceous Yambol-Burgas region of the Eastern Srednogorie continental arc is characterized by unusually large volumes of mafic shoshonitic and ultra-K magmatism represented by high-Mg cumulitic rocks, and nepheline-normative ankaramites, absarokites and shoshonitic (high-alumina) basalts. The cumulitic rocks consist of phenocrysts of clinopyroxene and olivine ) with inclusions of spinel (Cr#75-78). Olivine high-Fo cores and clinopyroxene host glassy melt inclusions which have nephelinenormative compositions with ankaramitic CaO/Al 2 O 3 ratios (N 1), low SiO 2 (47.4-50.0 wt.%), high MgO (7.5-10.8 wt.%), high total alkalis and shoshonitic K 2 O/Na 2 O ratios (N1). Electron microprobe and LA-ICPMS analyses demonstrate that parental magma was a high-Ca primitive mantle melt. Melt inclusions from the less Fo 85 rim approach absarokite composition with CaO/Al 2 O 3 ratios b 1, lower MgO (5.2 wt.%), and higher total alkalis and K 2 O/Na 2 O ratio. The ankaramitic rocks are strongly porphyritic, composed of phenocrysts of altered olivine with spinel inclusions and large clinopyroxene. Their major and trace element compositions are similar to those of melt inclusions hosted in the high-Fo 91-90 cores and clinopyroxene of the cumulitic rock. The absarokites differ from the high-K ankaramites by slightly higher SiO 2 (50.6-52.7 wt.%), Al 2 O 3 and alkali-oxide contents, lower FeO and MgO and particularly low CaO/Al 2 O 3 (0.6-0.9) ratio. Compared to the absarokites, shoshonitic basalts have similar SiO 2 (50.2-52.8 wt.%) at lower MgO contents and CaO/Al 2 O 3 ratios (0.37-0.53). The presented extensive set of major and trace element data on melt inclusions and whole rocks, along with their main phenocryst compositions, is used to constrain the crystallization temperatures and pressures of the most primitive ankaramites. We suggest that ankaramite compositions are formed by melting of a garnet-free metasomatized mantle source rather than by melting of lower crustal cumulates. Numerical modelling demonstrates that the generation of absarokites and shoshonitic basalts is compatible with fractionation of olivine and clinopyroxene from ankaramitic magma. The high-Mg chemistry of cumulitic rocks is explained as the result of accumulation of these minerals.

“…Based on tectonic reconstructions (Dercourt et al, 1986;Gealey, 1988;Stampfli and Borel, 2004), the continuous slab (down to a depth of approximately 1200 km) imaged by seismic tomography would be composed of different sections of oceanic and continental mantle lithosphere van Hinsbergen et al, 2005), corresponding to the oceanic basins and continental terranes. Delamination of the continental crust of the terranes from the underlying continental mantle lithosphere has been proposed in order to explain the rather continuous slab , nappe stacking and metamorphism in the Aegean (van Hinsbergen et al, 2005, Jolivet and based on the geological record of Crete (e.g.…”
