“…Schematic cartoon of potential Inland and Seaward Kaikōura Range and fault development through time in the context of the rotating and southward migrating Hikurangi subduction margin. Figure adapted from Jiao et al (), with tectonic reconstruction after King (), relative plate motions interpolated from Cande and Stock (), and rotation of eastern North Island relative to the Australian Plate simplified from Lamb (). Note that our data set does not constrain timing or amounts of rotation and thus would also be consistent with the model of Little and Roberts () with rotation of faults limited to NE end of the Clarence Fault.…”

“…In a recent publication, Jiao et al (2017) estimate that an increase in convergence rates in eastern Marlborough took place at~4 Ma. This is the same time period over which the Hikurangi margin and dextral motion along the main Marlborough Faults propagated southward, and the plate boundary zone widened (Holt & Haines, 1995;Knuepfer, 1992;Little & Jones, 1998;Little & Roberts, 1997), suggesting a potential relationship among these phenomena.…”

The Timing and Style of Oblique Deformation Within New Zealand's Kaikōura Ranges and Marlborough Fault System Based on Low‐Temperature Thermochronology

The ~150‐km‐wide dextral Marlborough Fault System and adjacent Kaikōura Mountains accommodate oblique convergence between the Pacific and Australian plates at the NE end of the South Island, New Zealand. Low‐temperature thermochronology from this region places new limits on the timing and style of Marlborough faulting and mountain building. We sampled rocks for apatite and zircon (U‐Th/He) and apatite fission track dating from a range of elevations spanning ~2 km within the Kaikōura Ranges, which stand high above the active Marlborough dextral faults. The data reveal Miocene cooling localized to hanging wall rocks, first along the Clarence Fault in the Inland Kaikōura Range, then along the Jordan Thrust in the Seaward Kaikōura Range, followed by widespread, rapid cooling reflected in all samples across the study area starting at ~5 Ma. Our results suggest that topographic relief in this region predates the onset of dextral faulting and that portions of the Marlborough Faults were once thrust faults that coincided with the early development of the transpressive plate boundary. We relate Pliocene to present rapid exhumation across the field site, including at low‐elevation sample sites in Marlborough Fault foot walls, to seaward translation and overthrusting of crust atop the downgoing slab by dextral Marlborough Fault motion. Our results show that spatial and temporal patterns in exhumation reflect a complex and evolving deformation field in the Marlborough Fault System over the past ~25 million years of Kaikōura orogeny.

“…Recent improvements in our ability to obtain uplift and subsidence histories from geologic records have increased our understanding of how deep-Earth processes interact with Earth's surface (e.g., Benowitz et al, 2014;Fitzgerald et al, 2014;Jiao et al, 2017;Liu et al, 2017;Warren-Smith et al, 2016). In Fiordland, Sutherland et al (2009) showed that zones of high exhumation rates and topographic growth track the along-strike and downdip development of the subducting Australian Plate, suggesting that the subducting slab was the main driver of uplift and exhumation in the overriding plate.…”

The Age and Origin of Miocene‐Pliocene Fault Reactivations in the Upper Plate of an Incipient Subduction Zone, Puysegur Margin, New Zealand

Structural observations and 40Ar/39Ar geochronology on pseudotachylyte, mylonite, and other fault zone materials from Fiordland, New Zealand, reveal a multistage history of fault reactivation and uplift above an incipient ocean‐continent subduction zone. The integrated data allow us to distinguish true fault reactivations from cases where different styles of brittle and ductile deformation happen together. Five stages of faulting record the initiation and evolution of subduction at the Puysegur Trench. Stage 1 normal faults (40–25 Ma) formed during continental rifting prior to subduction. These faults were reactivated as dextral strike‐slip shear zones when subduction began at ~25 Ma. The dextral shear zones formed part of a transpressional regime (Stage 2, 25–10 Ma) that included minor reverse motion and modest uplift above the leading edge of the subducting slab as it propagated below Fiordland. At 8–7 Ma (Stage 3), trench‐parallel faults accommodated the first and only episode of pure reverse motion. Reconstructions confirm that these faults formed when the slab reached mantle depths and collided with previously subducted crust. At 5–4 Ma (Stage 4), trench‐parallel faults accommodated oblique‐reverse motion when an oceanic ridge collided obliquely with the Puysegur Trench. Stages 3 and 4 both accelerated rock uplift and topographic growth in short pulses. A return to strike‐slip motion occurred after ~4 Ma (Stage 5) when deformation localized onto the Alpine Fault. These results highlight how the rock record of faulting links displacements occurring at Earth's surface to events occurring both at the trench and deep within the lithosphere during subduction.
