TLDR
In this paper, it was shown that andesites are generated through the interaction of mantle-derived magmas with lower crustal melts and restites and differences between Ruapehu and Taranaki andesite reflect contrasting physical conditions during melting as well as subtle variations in the mantle and crustal source compositions.About:

Microsampling and Isotopic Analysis of Igneous Rocks: Implications for the Study of Magmatic Systems
TL;DR: Isotopic fingerprinting has been used to trace magmatic processes and the components that contribute to magmas as mentioned in this paper, and the relationship between isotopic composition and petrographic features, such as dissolution surfaces, can be used to constrain magma evolution pathways involving open system processes.

Deep Carbon Emissions from Volcanoes
TL;DR: The role of CO2 degassing from the Earth is clearly fundamental to the stability of the climate, and therefore to life on Earth as discussed by the authors, but the uncertainty in our knowledge of this critical input into the geological carbon cycle led Berner and Lagasa (1989) to state that it is the most vexing problem facing us in understanding that cycle.

Balancing the plate motion budget in the South Island, New Zealand using GPS, geological and seismological data
TL;DR: In this paper, the authors interpret GPS, geological and seismological data describing the active deformation in the South Island, New Zealand by using an elastic, rotating block approach that automatically balances the Pacific/Australia relative plate motion budget.

The 26·5 ka Oruanui Eruption, Taupo Volcano, New Zealand: Development, Characteristics and Evacuation of a Large Rhyolitic Magma Body
TL;DR: The Oruanui rhyolite was formed in a single stage of evolution from a more primitive forerunner but by rapid rejuvenation of a longer-lived polygenetic, multi-age ‘stockpile’ of silicic plutonic components in the Taupo magmatic system.

Trends in rhyolite geochemistry, mineralogy, and magma storage during the last 50 kyr at Okataina and Taupo volcanic centres, Taupo Volcanic Zone, New Zealand
TL;DR: The most frequently active rhyolitic zone on Earth is the Taupo Volcanic Zone of New Zealand (TVC) as mentioned in this paper, where the most frequent active rhyolite eruptions occur at the Okataina and TVC volcanoes.

Geochemical and geodynamical constraints on subduction zone magmatism
TL;DR: In this article, a quantitative model has been developed for IAB petrogenesis with the transfer of trace elements from the slab to the mantle wedge being modelled with empirical slab-fluid partition coefficients whilst the mantlewedge to arc-crust transfer is constrained by melt-solid partitioning.

Element transport from slab to volcanic front at the Mariana arc
TL;DR: Agarwal et al. as mentioned in this paper presented a comprehensive geochemical data set for the most recent volcanics from the Mariana Islands, which provides new constraints on the timing and nature of fluxes from the subducting slab.

Volcanic and structural evolution of Taupo Volcanic Zone, New Zealand: a review
Colin J. N. Wilson,Bruce F. Houghton,Michael McWilliams,Marvin A. Lanphere,Steve Weaver,Roger M. Briggs +5 more
TL;DR: The history of the Taupo Volcanic Zone (TVZ) can be divided into two categories: the old TVZ from 2.0 Ma to 0.34 Ma and the young TVZ between 0.9 and 0.6 Ma as discussed by the authors.

Origin of calc-alkaline series lavas at Medicine Lake Volcano by fractionation, assimilation and mixing
TL;DR: The results of experimental studies and examination of variations in major elements, trace elements and Sr isotopes indicate that fractionation, assimilation and magma mixing combined to produce the lavas at Medicine Lake Highland as mentioned in this paper.
