Cataclastic faults along the SEMP fault system (Eastern Alps, Austria) — A contribution to fault zone evolution, internal structure and paleo-stresses

Changing fluid chemistry during continuous shearing in cataclastic fault zones – a semiquantitative analysis based on cathodoluminescence, microprobe and stable isotope analysis

“…Coincidentally to field data acquisition and structural analysis (Hausegger and Kurz, 2013), oriented samples from all structural elements (host rock, damage zone and fault core) of fault zones were taken at the study sites described above (Fig. 2).…”

“…Site description rious orientations and displacements (Hausegger and Kurz, 2013). Site Haindlkar is located in the Gesäuse Mountains and directly affected by the Ennstal/Gesäuse fault, a segment of the SEMP fault system.…”

“…Caine et al, 1996;Caine and Foster, 1999;Billi et al, 2003;Kim et al, 2004;Faulkner et al, 2010) and discriminates between host rock, damage zone, transition zone and fault core. Fault type classification and particle analysis were adopted from Hausegger and Kurz (2013), who describe a continuous fault zone evolution due to increasing displacement from initial fault type III over fault type II to mature fault type I (Fig. 3).…”

“…The investigated fault zone development proceeds according to Mohr-Coulomb fracture evolution described from Riedel type experimental configurations. The evolution of these cataclastic fault cores is depending on orientation with respect to principal stress axis as wellas pre-existing and predominant structures (Hausegger and Kurz, 2013).…”
