Heat output from spreading and rifting models of the Taupo Volcanic Zone, New Zealand
A conceptual model of the Taupo Volcanic Zone (TVZ) is developed, to a depth of 25 km, formed from three constant density layers. The upper layer is formed from eruption products. A constant rate of eruption is assumed, which eventually implies a constant rate of extension, and a constant rate of volumetric creation in the middle and bottom layers. Tectonic extension creates volume which can ac...

متن کاملGeothermal waters from the Taupo Volcanic Zone , New Zealand : Li , 1 B and Sr isotopes characterization
11 12 13 In this study, we report chemical and isotope data for 23 geothermal water samples collected in New Zealand 14 within the Taupo Volcanic Zone (TVZ). We analyzed major and trace elements including Li, B and Sr and their 15 isotopic compositions ( 7 Li, 11 B, 87 Sr/ 86 Sr) in high temperature geothermal waters collected from deep boreholes 16 in different geothermal fields (Ohaaki, Wa...
متن کاملNew Zealand: dating the transition between volcanism in the Coromandel Arc and the Taupo Volcanic Zone
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 the NNW-oriented Miocene–Pliocene Coromandel Volcanic Zone to the northeast-oriented active Taupo Volcanic Zone. The volcanic rocks marking this transition are exposed in the Tauranga Basin and adjacent Kaim...
متن کاملModeling of Cooling Plutons in the Taupo Volcanic Zone, New Zealand
Modeling carried out using a super-critical version of TOUGH2 has been used to investigate different source models for the geothermal fields in the Taupo Volcanic Zone (TVZ), New Zealand. The models describe the cooling, by groundwater circulation, of magmatic intrusions into the upper 8 km of the crust. By comparing the calculated surface heat flux from these intrusions with actual thermal out...
