Mineral-melt vanadium oxybarometry for primitive arc magmas: effect of hydrous melt composition on fO2 estimates Contrib. Mineral. Petrol. (IF 3.5) Pub Date : 2024-04-04
Abstract If primitive arc magmas are primarily oxidized or if they acquire their oxidizing character during crustal evolution remains debated. Mineral-melt V partitioning is extremely redox sensitive and has the potential to resolve this debate, but critical low-temperature, hydrous experimental partitioning data are limited. We present new experimental V partitioning data for olivine-melt, spinel-melt

Towards an integrated texture toolkit, 1: unveiling the complex relationship between crystal shape and fabric in EBSD data Contrib. Mineral. Petrol. (IF 3.5) Pub Date : 2024-04-04 Ryan M. Currier, Tushar Mittal, Paulo J. Hidalgo
Rock textures observed via thin section are skewed from their true 3D nature. This is due to various cut effects—artifacts introduced due to the lower dimensional nature of the thin section relative to the rock. These cut effects can be corrected, and several methods have been developed to invert crystal shape and crystal size, but with each process performed separately and sequentially. With the ongoing

Lithium systematics in the Krafla volcanic system: comparison between surface rhyolites and felsic cuttings from the Iceland deep drilling project -1 (IDDP-1) Contrib. Mineral. Petrol. (IF 3.5) Pub Date : 2024-04-04 E. A. Cortes-Calderon, B. S. Ellis, T. Magna, L. Tavazzani, P. Ulmer
The unexpected discovery of felsic magma by the Iceland Deep Drilling Project-1 (IDDP-1) in the Krafla volcanic system (KVS) presents a unique opportunity to investigate pre-eruptive lithium (Li) dynamics and establish a more direct connection between magma reservoirs and volcanic deposits. Our study provides new insights into Li abundances and isotope compositions in bulk-rock, minerals, and groundmass

Experimental determination of Fe–Mg interdiffusion in orthopyroxene as a function of Fe content Contrib. Mineral. Petrol. (IF 3.5) Pub Date : 2024-04-04 Maria A. Dias, Ralf Dohmen
We have measured the dependence of the Fe–Mg interdiffusion coefficient, DFe-Mg, on the ferrosilite component in orthopyroxene, which so far has not been experimentally calibrated. Diffusion couples, consisting of approximately 1 µm thin-films were deposited by pulsed laser ablation on orthopyroxene crystals of En91Fs9 composition. Diffusion experiments were carried out at atmospheric pressure in vertical

Elastic thermobarometry on metapelites across the crustal section of the Famatinian Arc, Argentina Contrib. Mineral. Petrol. (IF 3.5) Pub Date : 2024-04-01 Emanuel Giovanini, Kenneth S. Befus, Juan E. Otamendi, Eber Cristofolini, Tomas Guerreiro, Miguel Cisneros
We applied elastic thermobarometry on garnet-bearing migmatites along two transects through the crustal section at Sierra Valle Fértil-La Huerta, Argentina. We performed quartz-in-garnet barometry and zircon-in-garnet thermometry on metapelites from different paleo-depths across the crustal section. Our work recovers entrapment pressures ranging from 240 to 1330 MPa and entrapment temperatures between

Lower crustal assimilation revealed by sulfur isotope systematics of the Bear Valley Intrusive Suite, southern Sierra Nevada Batholith, California, USA Contrib. Mineral. Petrol. (IF 3.5) Pub Date : 2024-03-29 Hervé Rezeau, Oliver Jagoutz, Patrick Beaudry, Benjamin. Z. Klein, Gareth Izon, Shuhei Ono
The origin of the wide range of sulfur isotope compositions (i.e., δ34S) measured in arc rocks remains debated. While the observed δ34S variability has been attributed to slab-related fluids that flux the sub-arc mantle, others have argued that it primarily reflects crustal-derived processes by some combination of magmatic differentiation, country rock assimilation, and/or degassing. Here, we present

Microstructural and isotopic analysis of shocked monazite from the Hiawatha impact structure: development of porosity and its utility in dating impact craters Contrib. Mineral. Petrol. (IF 3.5) Pub Date : 2024-03-13
Abstract U–Pb geochronology of shocked monazite can be used to date hypervelocity impact events. Impact-induced recrystallisation and formation of mechanical twins in monazite have been shown to result in radiogenic Pb loss and thus constrain impact ages. However, little is known about the effect of porosity on the U–Pb system in shocked monazite. Here we investigate monazite in two impact melt rocks
