From the Kermadec Trench to the southern termination of the Hikurangi Trough: results of the GEODYNZ-SUD, Leg 1 swath-mapping survey

Collot, Jean-Yves Delteil, Jean Lewis, Keith

EM12 swath-mapping and geophysical data collected during GEODYNZ-SUD cruise leg 1 along the Kermadec-Hikurangi margin reveal the structures associated with the transition from oblique intraoceanic subduction to very oblique sub-continental subduction and intra-continental transpression. Partitioning between strike-slip and compressional...

From Oblique Subduction to Intra-Continental Transpression: Structures of the Southern Kermadec-Hikurangi Margin from Multibeam Bathymetry, Side-Scan Sonar and Seismic Reflection

Collot, Jean-Yves Delteil, Jean Lewis, Keith B.

The southern Kermadec-Hikurangi convergent margin, east of New Zealand, accommodates the oblique subduction of the oceanic Hikurangi Plateau at rates of 4-5 cm/yr. Swath bathymetry and sidescan data, together with seismic reflection and geopotential data obtained during the GEODYNZ-SUD cruise, showed major changes in tectonic style along the...
