“…10). The length-to-width ratio equal to 3, calculated for the Mnin stepover demonstrates an almost best fit to the quasi-linear positive power law relationship: y = 2.69x 0.97 /R 2 = 0.93 (de Joussineau and Aydin 2009). This puts the Mnin stepover close to the most typical structures of this type.…”

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.

“…Although it is difficult to define uncertainty regarding the fault dimensions measured from published geologic and seismologic maps, recent experimental (Otsuki and Dilov, 2005) and site-specific field data from the same tectonic region and lithology and similar resolution (de Joussineau and Aydin, 2009) appear to confirm this trend. It is also interesting to note that larger size of steps is associated with faults having larger maximum slip magnitudes (Aydin and Nur, 1982;).…”

“…1a). This discontinuous characteristic of strike-slip faults has been reported for simple incipient faults (Segal and Pollard, 1980;1983;Gamond, 1983;Willemse et al, 1987;Peacock and Sanderson, 1995) as well as for mature crustal scale faults (Aydin and Nur, 1982;Barka and Kadinsky-Cade, 1988;Wesnousky, 1988;Stirling et al, 1996, Kim et al, 2004 and is thought to be pertinent to a number of properties of strike-slip fault systems including their permeability structure (Sibson, 1985;Martel and Peterson, 1991;Aydin, 2000;Odling et al, 2004), the dynamics and size of earthquake ruptures (Aki, 1989;Wesnousky, 2006;Shaw and Dieterich, 2007), the spatial and temporal evolution of earthquakes (Dewey, 1976;Toksöz et al, 1979;Stein et al, 1997), and growth and scaling of faults (de Joussineau and Aydin, 2009;Scholz, 2002).…”

“…As faults grow longer, they are able to interact with the neighboring faults at greater distances. Furthermore, it has been shown that faults extend their lengths by linkage and coalescence of smaller segments through fault steps in order to accommodate larger amount of slip (Segall and Pollard, 1983;Martel et al, 1988;Martel, 1990;Peacock, 1991;Peacock and Sanderson, 1995;Cartwright et al, 1995;Dawers and Anders, 1995;Pachell and Evans, 2002;Scholz, 2002;Myers and Aydin, 2004;de Joussineau and Aydin, 2009). It follows that the length-slip plots for faults which grew by linkage and coalescence is not actually continuous but rather have sharp "jumps"…”

Increases in the dimensions of strike-slip faults including fault length and thickness of fault rock and the surrounding damage zone collectively provide quantitative definition of fault growth and are commonly measured in terms of slip. A vast amount of field data shows that fault dimensions increase in some fashion as the slip across faults increases though these relationships may not be simple. The field observations also indicate that a common mechanism for fault growth in the brittle upper crust is fault lengthening by linkage and coalescence of neighboring fault segments or strands. In addition, the mechanism of fault zone widening is spreading of fault rock via cataclastic deformation into highly fractured inner damage zone. The most important underlying mechanical reason in both cases is prior weakening of the rocks surrounding a fault's core and between neighboring fault segments by fault-related fractures. Using field observations together with effective medium models, this paper attempts to constrain the reduction in the effective elastic properties of rock in terms of the orientation and density of the fault-related brittle fractures. Calculated and extrapolated values of the Young's and shear moduli for idealized fractured rock masses at fault steps and inner damage zones provide insight into the degree of strength degradation as a function of the angle between fracture sets and fracture density and how increasing fracture density may eventually facilitate fault growth via cataclastic deformation of fractured rock masses.

“…It is known that segmentation is a fundamental feature of fault development [4,[30][31][32][33][34]. A similar segmented structure of fault zones extends throughout the seismogenic depth, deeper that 10 km in the earth's crust [33,34].…”
