Analogue modelling of strain partitioning along a curved strike-slip fault system during backarc-convex orocline formation: Implications for the Cerna-Timok fault system of the Carpatho-Balkanides

Large-scale strike-slip faults are associated with significant strain partitioning in releasing/restraining bends and often display map-view curvatures ending horse-tail geometries. Such commonly indentation tectonics, where shortening front of indenters is transferred laterally to transpression, the formation transtensional/extensional basins. We investigate how these structurally distinct domains kinematically linked by means a crustal-scale analogue modelling approach deformable crust moved against stable rigid indenter. The demonstrates that geometry indenter major controlling parameter driving deformation transfer from thrusting transpression transtension, whereas rotation mobile plate controls opening triangular shaped transtensional Flow ductile leads distribution over wider area, facilitating splaying into transtension/extension behind Our results show very good correlation Moesian Carpatho-Balkanides system South-Eastern Europe, partitioned around dextral Cerna Timok Balkanides part neighbouring South Carpathians.
