Submarine back-arc lava with arc signature: Fonualei Spreading Center, northeast Lau Basin, Tonga
[1] We present major, volatile, and trace elements for quenched glasses from the Fonualei Spreading Center, a nascent spreading system situated very close to the Tofua Volcanic Arc (20 km at the closest), in the northeast Lau Basin. The glasses are basalts and basaltic andesites and are inferred to have originated from a relatively hot and depleted mantle wedge. The Fonualei Spreading Center sh...
متن کاملMelt/harzburgite reaction in the petrogenesis of tholeiitic magma from Kilauea volcano, Hawaii
We use the results of elevated pressure melting experiments to constrain the role of melt/mantle reaction in the formation of tholeiitic magma from Kilauea volcano, Hawaii. Trace element abundance data is commonly interpreted as evidence that Kilauea tholeiite is produced by partial melting of garnet lherzolite. We experimentally determine the liquidus relations of a tightly constrained estimat...
متن کاملDeep magma transport at Kilauea volcano, Hawaii
The shallow part of Kilauea’s magma system is conceptually well-understood. Long-period and short-period (brittle-failure) earthquake swarms outline a near-vertical magma transport path beneath Kilauea’s summit to 20 km depth. A gravity high centered above the magma transport path demonstrates that Kilauea’s shallow magma system, established early in the volcano’s history, has remained fixed in...

Egmont Volcano (Mt Taranaki) is located 140 km west of the INTRODUCTION Taupo Volcanic Zone (TVZ), the principal locus of volcanic activity Egmont Volcano is a 2518 m high stratovolcano (Mt in the North Island of New Zealand, and is one of four closely Taranaki) resting on an extensive ring plain of volcanic associated Quaternary andesitic volcanoes in Taranaki province. debris in Taranaki prov...
متن کاملTiming magma ascent at Popocatepetl Volcano , Mexico , 2000 ^ 2001
Magnetic anomalies may be used to constrain magma ascent and are useful as precursors to eruptions especially when correlated with other geophysical and geochemical data. In this paper we present multiparameter data on the magnetics, dome morphology, geochemistry and seismicity associated with the December 2000^January 2001 eruptions, the largest of the recent eruptions at Popocatepetl Volcano....
