It is generally accepted that tectonic earthquakes may trigger volcanic activity, although the
underlying mechanisms are poorly constrained. Here, we review current knowledge, and …

Accurate dating of young (< 1 Ma) volcanic eruptions has long been a challenge for modern
geochronology given the scarcity of datable mineral phases and low quantities of radiogenic …

This paper provides a comprehensive review of the sinter deposits, formed largely of opal-A,
that are form around hot springs and geysers throughout the world. The discharge aprons …

ABSTRACT Tephra deposits in Aotearoa New Zealand (ANZ) have been studied for> 180
years. The now-global discipline of tephrochronology, which has some developmental roots …

Tephrochronology is of paramount importance in New Zealand where paleoclimate studies
use ages of volcanic ash layers as chronological makers. Maar lakes in the Auckland …

Investigation of active faults is crucial for the seismic hazard assessment and, in the case of
volcanic belts, it provides a deeper understanding of the interactions between volcanism …

Apatite (U–Th)/He (AHe) dating generally assumes that grains can be accurately and
precisely modeled as geometrically perfect hexagonal prisms or ellipsoids in order to …

Hydrothermal eruptions are the most violent and hazardous phenomena within geothermal
fields. The largest of these may produce kilometer-sized craters and breccia deposits that …

Northern New Zealand is an important site for understanding Last Glacial Interval (LGI)
paleoclimate dynamics, since it is influenced by both tropical and polar climate systems …

Abstract In the central Taupo Volcanic Zone, extensive zeolite (mordenite±clinoptilolite)
alteration occurs in late Quaternary rhyolitic vitric tuffs that were deposited in a lake formed …
