Caldera volcanism and rift structure in the Taupo Volcanic Zone, New Zealand

  title={Caldera volcanism and rift structure in the Taupo Volcanic Zone, New Zealand},
  author={Jim Cole and Karl D. Spinks},
Abstract The Taupo Volcanic Zone (TVZ) is an active continental volcanic arc/back-arc basin in central North Island, New Zealand. It is the youngest area of volcanic activity that extends southwards from the Coromandel Volcanic Zone (CVZ), where andesitic volcanism began c. 18 Ma and rhyolitic volcanism c. 10 Ma. It is an extensional basin (average c. 8 mm a−1) with numerous, predominantly normal (dip >60°) faults within the Taupo Rift, but with some strike-slip component. TVZ can be divided… 
A two million-year history of rifting and caldera volcanism imprinted in new gravity anomaly compilation of the Taupō Volcanic Zone, New Zealand
ABSTRACT The Taupō Volcanic Zone (TVZ) is characterised by a negative residual gravity anomaly that correlates with a zone of normal faulting, subsidence and voluminous silicic volcanism from c. 2
Rapid Evolution of Subduction‐Related Continental Intraarc Rifts: The Taupo Rift, New Zealand
The evolution of the continental intraarc Taupo Rift in the North Island, New Zealand, is rapid, significantly faster than comparative intracontinental rifts such as the African Rifts. Based on our
Volcano-structure of El Hierro (Canary Islands)
ABSTRACT The first complete volcano-structural map of El Hierro (Canary Islands, Spain) has been developed in order to provide a tool for volcano-tectonic analyses and volcanic hazard evaluation on

Structural control and origin of volcanism in the Taupo volcanic zone, New Zealand
Taupor volcanic zone (TVZ) is the currently active volcanic arc and back-arc basin of the Taupo-Hikurangi arc-trench system, North Island, New Zealand. The volcanic arc is best developed at the
Taupo Volcanic Zone and Central Volcanic Region Backarc Structures of North Island, New Zealand
Volcanism in North Island, New Zealand, is related to subduction within the Taupo-Hikurangi arc-trench system. The central volcanic region (CVR) is a wedge-shaped basin, approximately 4 m.y. old,
Caldera Volcanoes of the Taupo Volcanic Zone, New Zealand
The Taupo volcanic zone (TVZ) has been active since 2 Ma and has erupted >104 km3 of dominantly rhyolitic magma during the last 1 m.y. Most of the volcanism is concentrated in a 125×60 km area
Physical geology and eruptive history of the Matahina Ignimbrite, Taupo Volcanic Zone, North Island, New Zealand
Abstract The Matahina Ignimbrite is a 280 ka ash‐flow sheet that erupted from Haroharo Caldera in the Okataina Volcanic Centre, northern Taupo Volcanic Zone, North Island, New Zealand. The ignimbrite

Summary New Zealand lies on the boundary between the Pacific and Indian plates. In the vicinity of North Island, oceanic crust of the Pacific plate is subducted obliquely beneath continental crust of
40Ar/39Ar ages of silicic volcanic rocks in the Tauranga‐Kaimai area, New Zealand: Dating the transition between volcanism in the Coromandel Arc and the Taupo Volcanic Zone
Abstract Subduction‐related volcanism in the northern part of the North Island of New Zealand shifted abruptly during the late Pliocene. This study focuses on the transition, in time and space, from
Extensional fault kinematics within the Taupo Volcanic Zone, New Zealand: Soft‐linked segmentation of a continental rift system
Abstract The Taupo Volcanic Zone (TVZ) is a young (<2 Ma) arc‐backarc system in continental crust at the southern end of the Havre Trough characterised by intense volcanism and geothermal activity.
Geochronological and geochemical evolution of late Cenozoic volcanism in the Coromandel Peninsula, New Zealand
Abstract The Coromandel Peninsula comprises the central subaerial part of the late Cenozoic Coromandel Volcanic Zone (CVZ) of New Zealand and hosts the Hauraki Goldfield. Some 73 K‐Ar and 9 zircon
