Strain partitioning between structural domains in the forearc of the Hikurangi subduction zone, New Zealand
Article Abstract:
An deformation of an exposed forearc in the Pacific-Australian plate convergence zone along the Hikurangi margin, New Zealand is examined via geologic mapping and strain analysis. Partitioning of strain manifested in extension, contraction, and strike-slip domains that lengthen and trend parallel to the margin. Movement oblique to the convergent zone is transferred across the plate boundary. Much of the margin-parallel motion and 6% of the motion perpendicular to the boundary are accounted for by the estimated deformation rates.

Partition between collision and subduction accretionary prisms along an inherited transcurrent fault zone: New insights on the Taiwan fold and thrust belt
Article Abstract:
A new geotectonic framework of the Taiwan orogen is presented in agreement with the hypothesis of an oblique arc-arc collision. The scheme considers satellite-derived gravity anomalies and seismic profiles from the southern Taiwan offshore. The structural evolution was controlled by the Ryukyu subduction, and by the Luzon arc progression, since the middle Miocene. The northern arc-arc collisional prism is distinguished by an unroofed duplex culmination linked with passive roof thrust.

Subduction zone retreat and recent tectonics of the South Island of New Zealand
Article Abstract:
A study was conducted on the tectonics and subduction zone retreat of the central South Island of New Zealand. The differential amounts of subduction zone retreat beneath the orogen were found to cause the orogenic style strike variations in the area. Results also show that subduction zone retreat may cause local topographic lows wherein intermontane basins and associated lakes may for.
