TL;DR: The volatile contents of melt inclusions trapped within phenocrysts of quartz and feldspar in peralkaline rhyolites from Mayor Island, New Zealand, have been studied using Fourier transform infrared spectroscopy and ion microprobe analyses.

TL;DR: Palaeomagnetic data from lithic clasts collected at 46 sites within layers 1 and 2 of the 1.8-ka Taupo ignimbrite, New Zealand, have been used to determine the palaeotemperatures and thermal structure of the deposit on its emplacement as discussed by the authors.

TL;DR: In this paper, a detailed characterization of the proximal deposits is developed and used to interpret the range of styles and intensities of the vents, including changes with time, and evaluate the extent to which current volcanic plume models are compatible with the depositional patterns at Tarawera.

TL;DR: A fine-depleted ignimbrite was found in the pyroclastic flow as discussed by the authors, which is largely depleted in the finer constituents and is clast-supported for all clasts exceeding about 2 mm in size.

TL;DR: A series of alternating phreatomagmatic ("wet") and magmatic ("dry") basaltic pyroclastic deposits forming the Crater Hill tuff ring in New Zealand contains one unit (M1) which can only be interpreted as the products of mixing of ejecta from simultaneous wet and dry explosions at different portions of a multiple vent system as discussed by the authors.
