This layer shows the interpreted surface locations of active plate and microplate boundaries, in and around Te Riu-a-Māui / Zealandia. The layer was newly-compiled for, and is part of, the 'Tectonic map of Te Riu-a-Māui / Zealandia' 1:8 500 000 dataset.

This layer shows the observed and calculated velocities of active plate motions at selected surface locations in and around Te Riu-a-Māui / Zealandia. Velocities are shown relative to a fixed Australian Plate using the Global Strain Rate Model version 2.1. The layer was newly-compiled for, and is part of, the 'Tectonic map of Te Riu-a-Māui / Zealandia' 1:8 500 000 dataset.

This layer shows interpreted continental, oceanic, Large Igneous Province and island arc crust in and around Te Riu-a-Māui / Zealandia. Areas of poorly constrained crust are identified. High-level geological units of Te Riu-a-Māui / Zealandia comprise 500-100 Ma basement of Western Province terranes, Western Province Median Batholith, Eastern Provinces terranes and Eastern Province allochthons, and

This layer shows the interpreted depths to the top of actively subducting slabs in and around Te Riu-a-Māui / Zealandia, as indicated by seismicity. Slab depths are represented by selected contours. The layer was newly-compiled for, and is part of, the 'Tectonic map of Te Riu-a-Māui / Zealandia' 1:8 500 000 dataset.

This layer shows the interpreted ages of oceanic crust around Te Riu-a-Māui / Zealandia, as derived from seafloor magnetic reversals. Crustal ages are represented by lines of equal age at 10 million year intervals. The layer was newly-compiled for, and is part of, the 'Tectonic map of Te Riu-a-Māui / Zealandia' 1:8 500 000 dataset.

This layer shows the interpreted location of spreading ridges, transform faults, and selected thrusts and other faults, in and around Te Riu-a-Māui / Zealandia. Ancillary information is provided about age, type of movement and plate boundary association. The layer was newly-compiled for, and is part of, the 'Tectonic map of Te Riu-a-Māui / Zealandia' 1:8 500 000 dataset.

This layer shows the interpreted location of volcanoes, volcanic centres, volcanic fields, calderas and selected upper crustal intrusions in and around Te Riu-a-Māui / Zealandia. Points are attributed by age range, and whether the tectonic setting of eruption is interpreted to be related to a plate boundary (i.e. subduction), to an intraplate age-progressive hotspot track, or to other intraplate volcanism. The layer was newly-compiled for, and is part of, the 'Tectonic map of Te Riu-a-Māui / Zealandia' 1:8 500 000 dataset.

This collection of datasets comprise the 'Tectonic map of Te Riu-a-Māui / Zealandia' 1:8 500 000 data compilation. It contains the geospatial layers showing the main tectonic features and bathymetric environment of the region surrounding Te Riu-a-Māui / Zealandia.

This layer shows the location of the interpreted subsurface extent of the subducted western and southern edges of the Hikurangi Plateau. The layer was newly-compiled for, and is part of, the 'Tectonic map of Te Riu-a-Māui / Zealandia' 1:8 500 000 dataset.

This layer shows the interpreted extent of Te Riu-a-Māui / Zealandia continental crust. The layer was newly-compiled for, and is part of, the 'Tectonic map of Te Riu-a-Māui / Zealandia' 1:8 500 000 dataset.
