On the Origin of Crystal-poor Rhyolites: Extracted from Batholithic Crystal Mushes
TL;DR: In this article, the feasibility of system-wide extraction of high-SiO2 interstitial melt from the mushes was analyzed, which can rationalize a number of observations in both the plutonic and volcanic record, such as abrupt compositional gaps in ignimbrites, the presence of chemically highly evolved bodies at the roof of subvolcanic batholiths, and the observed range of ages recorded by zircons in silicic magmas.

Silicic volcanism: an undervalued component of large igneous provinces and volcanic rifted margins
TL;DR: The role of silicic magmatism in the evolution of a large igneous province and rifted margin may therefore be largely overlooked as discussed by the authors, however, due to the lack of detailed structural features, such as dike swarms, major intrusions, and deeply subsided intracaldera µlls, the role of these volcanic rocks is not fully explored.

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.
Journal ArticleDOI
The volcanic, magmatic and tectonic setting of the Taupo Volcanic Zone, New Zealand, reviewed from a geothermal perspective
TL;DR: The Taupo Volcanic Zone (TVZ) is one of the world's most spectacular and productive areas of Quaternary silicic volcanism and geothermal manifestations as discussed by the authors.

Nomenclature of amphiboles
TL;DR: The Na-Ca-Mg-Fe-Mn-Li amphibole group was proposed in this article, which is defined by 0.50 apfu (atoms per formula unit), with members whittakerite and ottoliniite.

Role of the sub-continental lithosphere in magma genesis at active continental margins
TL;DR: In this paper, the relative contributions of the subduction and lithosphere components to the composition of active continental margin basalts can be calculated from their MORB-normalized geochemical patterns.
