Localization of intraplate deformation through fluid-assisted faulting in the lower-crust: The Flinders Ranges, South Australia
In this paper we present a hypothesis for localized, intraplate deformation in the continental crust of south-central Australia that involves fluid-assisted reactivation of faults in the mid- to lower crust. Using data from a temporary seismometer deployment in the Flinders Ranges, we show that earthquakes, relocated in a 3D velocity model, cluster in elongated low v<inf>p</inf> /. v<inf>s</inf> anomalies that extend to depths exceeding 20. km, and are aligned with the axis of the Flinders...[Show more]
