Magma reservoirs play a key role in controlling numerous processes in planetary evolution,
including igneous differentiation and degassing, crustal construction, and volcanism. For …

Tephrochronology (from tephra, Gk 'ashes') is a unique stratigraphic method for linking,
dating, and synchronizing geological, palaeoenvironmental, or archaeological sequences or …

The phase relationships contained in the magnetotelluric (MT) impedance tensor are shown
to be a second-rank tensor. This tensor expresses how the phase relationships change with …

Geothermal springs are model ecosystems to investigate microbial biogeography as they
represent discrete, relatively homogenous habitats, are distributed across multiple …

The large-scale volcanic lineaments in Iceland are an axial zone, which is delineated by the
Reykjanes, West and North Volcanic Zones (RVZ, WVZ, NVZ) and the East Volcanic Zone …

Calderas are important features in all volcanic environments and are commonly the sites of
geothermal activity and mineralisation. Yet, it is only in the last 25 years that a thorough …

The relatively low rates of magma production in island arcs and continental extensional
settings require that the volume of silicic magma involved in large catastrophic caldera …

Abstract The Broadlands-Ohaaki geothermal system is a boiling hydrothermal system
hosted by a sequence of Quaternary felsic volcanic rocks and Mesozoic metasediments …

The Taupo Volcanic Zone (TVZ) of New Zealand is characterised by extensive volcanism
and by high rates of magma production. Associated with this volcanism are numerous high …

Vigorous hydrothermal convection transfers 10 times the average continental heat flow
through the central Taupo Volcanic Zone (TVZ), a region of active extension (approximately …
