Origins and evolution of rhyolitic magmas in the central Snake River Plain: insights from coupled high-precision geochronology, oxygen isotope, and hafnium isotope analyses of zircon

Colón, Dylan; Bindeman, Ilya; Wotzlaw, Jörn-Frederik; Christiansen, Eric; Stern, Richard

2018 Contributions to Mineralogy and Petrology

doi:10.1007/s00410-017-1437-y

We present new high-precision CA-ID-TIMS and in situ U–Pb ages together with Hf and O isotopic analyses (analyses performed all on the same grains) from four tuffs from the 15−10 Ma Bruneau–Jarbidge center of the Snake River Plain and from three rhyolitic units from the Kimberly borehole in the...

The partitioning of sulfur between multicomponent aqueous fluids and felsic melts

Binder, Bernd; Wenzel, Thomas; Keppler, Hans

2018 Contributions to Mineralogy and Petrology

doi:10.1007/s00410-018-1445-6

Sulfur partitioning between melt and fluid phase largely controls the environmental impact of volcanic eruptions. Fluid/melt partitioning data also provide the physical basis for interpreting changes in volcanic gas compositions that are used in eruption forecasts. To better constrain some...

The elastic solid solution model for minerals at high pressures and temperatures

Myhill, R.

2018 Contributions to Mineralogy and Petrology

doi:10.1007/s00410-017-1436-z pmid:31983760

Abstract Non-ideality in mineral solid solutions affects their elastic and thermodynamic properties, their thermobaric stability, and the equilibrium phase relations in multiphase assemblages. At a given composition and state of order, non-ideality in minerals is typically modelled via excesses...

Petrology of spinel lherzolite xenoliths from Youkou volcano, Adamawa Massif, Cameroon Volcanic Line: mineralogical and geochemical fingerprints of sub-rift mantle processes

Njombie, Merlin Patrick Wagsong; Temdjim, Robert; Foley, Stephen F.

2018 Contributions to Mineralogy and Petrology

doi:10.1007/s00410-018-1438-5

Abstract The basaltic maar of Youkou, situated in the Adamawa Volcanic Massif in the eastern branch of the continental segment of the Cameroon Volcanic Line, contains mantle-derived xenoliths of various types in pyroclastites. Spinel-bearing lherzolite xenoliths from the Youkou volcano generally...

Orthopyroxene oikocrysts in the MG1 chromitite layer of the Bushveld Complex: implications for cumulate formation and recrystallisation

Kaufmann, Felix; Vukmanovic, Zoja; Holness, Marian; Hecht, Lutz

2018 Contributions to Mineralogy and Petrology

doi:10.1007/s00410-018-1441-x

Two typical mineral textures of the MG 1 chromitite of the Bushveld Complex, South Africa, were observed; one characterised by abundant orthopyroxene oikocrysts, and the other by coarse-grained granular chromitite with only minor amounts of interstitial material. Oikocrysts form elongate clusters...

Melt inclusion constraints on petrogenesis of the 2014–2015 Holuhraun eruption, Iceland

Hartley, Margaret; Bali, Enikö; Maclennan, John; Neave, David; Halldórsson, Sæmundur

2018 Contributions to Mineralogy and Petrology

doi:10.1007/s00410-017-1435-0 pmid:31983759

The 2014–2015 Holuhraun eruption, on the Bárðarbunga volcanic system in central Iceland, was one of the best-monitored basaltic fissure eruptions that has ever occurred, and presents a unique opportunity to link petrological and geochemical data with geophysical observations during a major...

Melt inclusion constraints on volatile systematics and degassing history of the 2014–2015 Holuhraun eruption, Iceland

Bali, E.; Hartley, M.; Halldórsson, S.; Gudfinnsson, G.; Jakobsson, S.

2018 Contributions to Mineralogy and Petrology

doi:10.1007/s00410-017-1434-1

The mass of volatiles emitted during volcanic eruptions is often estimated by comparing the volatile contents of undegassed melt inclusions, trapped in crystals at an early stage of magmatic evolution, with that of the degassed matrix glass. Here we present detailed characterisation of magmatic...

The origin of plagioclase phenocrysts in basalts from continental monogenetic volcanoes of the Kaikohe-Bay of Islands field, New Zealand: implications for magmatic assembly and ascent

Coote, Alisha; Shane, Phil; Stirling, Claudine; Reid, Malcolm

2018 Contributions to Mineralogy and Petrology

doi:10.1007/s00410-018-1440-y

Late Quaternary, porphyritic basalts erupted in the Kaikohe-Bay of Islands area, New Zealand, provide an opportunity to explore the crystallization and ascent history of small volume magmas in an intra-continental monogenetic volcano field. The plagioclase phenocrysts represent a diverse crystal...

Electrical conductivity of the plagioclase–NaCl–water system and its implication for the high conductivity anomalies in the mid-lower crust of Tibet Plateau

Li, Ping; Guo, Xinzhuan; Chen, Sibo; Wang, Chao; Yang, Junlong; Zhou, Xingfan

2018 Contributions to Mineralogy and Petrology

doi:10.1007/s00410-018-1442-9

In order to investigate the origin of the high conductivity anomalies geophysically observed in the mid-lower crust of Tibet Plateau, the electrical conductivity of plagioclase–NaCl–water system was measured at 1.2 GPa and 400–900 K. The relationship between electrical conductivity and...
