Ar/Ar geochronology associated with fault reactivation in Fiordland

Abstract: This is a 40Ar/39Ar geochrononology dataset from samples collected along transects across strain gradients associated with fault reactivation in Fiordland. The results have implications for Miocene-Pliocene fault reactivations in the upper plate of an incipient subduction zone at the Puysegur Margin of New Zealand. To understand the significance of the complex apparent age spectra (e.g. in light of cross-cutting relationships and other structural constraints), please see the full suite of integrated data presented in an accepted publication cited below.
