Evolution of the boundary between the western and central Lachlan Orogen: implications for Tasmanide tectonics

摘要: Differences in oblique overprinting, along‐strike complexity as well structural, metamorphic and timing constraints suggest that the boundary between western central subprovinces of Lachlan Orogen, currently designated by Governor Fault, cannot be a single structure. Previously limited data on nature kinematics fault/shear systems defining have led to varying scenarios for tectonic evolution Orogen. These either involve large‐scale strike‐slip displacement along with subsequent overthrusting or convergence oppositely vergent thrust‐systems translation. Geometrical constraints, fabric chronology kinematic indicators both Mt Wellington (Melbourne Zone) (Tabberabbera Fault Zones indicate maximum displacements relate thrusting duplex formation, followed minor faulting perhaps response slightly collision Melbourne ...
