Paleomagnetic constraints on the tectonic rotation of the southern Hikurangi margin, New Zealand
Plate reconstructions of the New Zealand region indicate substantial Cenozoic tectonic rotation of the Hikurangi margin. This study was undertaken to determine the rotational history of the northern Marlborough paleomagnetic domain in the southern part of the Hikurangi margin. Most Cenozoic rocks in the Marlborough region are unstably magnetised, and useful results were obtained only from late ...
متن کاملTwo new species and a new record of Comesomatidae (Nematoda, Araeolaimida) from Southern Hikurangi Margin, New Zealand.
We describe two new species and provide one new species record of the family Comesomatidae from a submarine canyon habitat on the Southern Hikurangi margin, New Zealand. Vasostoma hexodontium n. sp. is characterized by having an amphideal fovea with three turns, buccal cavity with six teeth and gubernaculum with long and straight caudal apophyses. Sabatieria dispunctata n. sp. is characterized ...
متن کاملEvaluation of Southern Hawkes Bay Coast
SUMMARY 1) The use of presence/absence data is a valid method for comparing communities from hard shore marine environments where the biota is relatively sessile. It is an extensively used method in botanical surveys and its use should be extended into the marine environment. 2) Blackhead had the highest species richness and the widest range of species diversity, suggesting a diversity of habit...
متن کاملMethane seepage and its relation to slumping and gas hydrate at the Hikurangi margin, New Zealand
Dissolved methane and high resolution bathymetry surveys were conducted over the Rock Garden region of Ritchie Ridge, along the Hikurangi margin, eastern New Zealand. Multibeam bathymetry reveals two prominent, northeast trending ridges, parallel to subduction along the margin, that are steep sided and extensively slumped. Elevated concentrations of methane (up to 10 nM, 10× background) within ...
متن کاملConduit margin heating and deformation during the AD 1886 basaltic Plinian eruption at Tarawera volcano, New Zealand
During explosive eruptions, a suspension of gas and pyroclasts rises rapidly within a conduit. Here, we have analysed textures preserved in the walls of a pyroclastic feeder dyke of the AD 1886 Tarawera basaltic Plinian fissure eruption. The samples examined consist of basaltic ash and scoria plastered onto a conduit wall of a coherent rhyolite dome and a welded rhyolitic dome breccia. We exami...
