The first-row transition element (FRTE) and high field strength element (HFSE) systematics are powerful tools for tracking the source and evolution of mantle-derived magmas. Clinopyroxene is generally considered a key fractionating mineral controlling the partitioning of trace elements between melt and residual solid during mantle melting.Although partitioning of FRTE and HFSE between clinopyroxene and basaltic melts has been well studied, experimental constraints on their partitioning behaviors in the presence of siliceous, aluminous and alkali-rich melts are still lacking. Here we present clinopyroxene-silicic melt (67-69 wt% SiO2) partitioning experiments at 1 bar pressure and 1070-1100 °C for Co, Mn, Ni, Cu, Zn, Fe, Sc, Cr, V, Ti, Zr, Hf, Nb, and Ta. Run products consist of diopsidic clinopyroxene coexisting with various melt compositions with non-bridging oxygen to tetrahedral cation ratio (NBO/T) ranging from 0.10 to 0.22.Using our new partition coefficients (Ds) and combining literature data we assess some of the effects of crystal chemistry and the melt composition on the partitioning of FRTE and HFSE in this simple system.We show that partitioning of FRTE varies from mildly incompatible (e.g., D = ~0.1−1 for V, Cu, and Zn) to highly compatible (e.g., D > 10 for Cr and Ni), with highest compatibilities observed for Ni (DNi = 13−34). The partitioning of HFSE varies from highly incompatible (D = 0.01−0.08) for Nb and Ta to mildly incompatible (D = 0.18−0.82) for Zr, Hf, and Ti. Our measured clinopyroxene-melt Ds are consistent with the theoretical predictions of the lattice strain model. Ds data for most tri-, tetra-, and pentavalent elements tend to increase with increasing tetrahedrally-coordinated Al This is the peer-reviewed, final accepted version for American Mineralogist, published by the Mineralogical Society of America.The published version is subject to change.

“…For charge balance calculations it was assumed that all samples contain solely tetravalent V. If V 3+ were also incorporated into reduced rutile samples, the excess of trivalent cations over H + and pentavalent cations would increase further, resulting in a higher concentration of oxygen vacancies. Additionally, the presence of V 5+ cannot be ruled out completely (Holycross and Cottrell, 2022). The presence of V 5+ instead of or simultaneously with V 4+ would reduce the concentration of oxygen vacancies in samples AA16-11, AS19-1, AS19-2, AS19-3, and DM1c.…”

“…Another redox sensitive trace element that occurs in high concentrations in rutile is V. Vanadium has been described as V 3+ , V 4+ , and V 5+ in rutile (e.g. Klemme et al, 2005;Lucassen et al, 2013;Holycross and Cottrell, 2020;Holycross and Cottrell, 2022). In experimental studies, V is abundant in rutile over a variety of oxygen fugacities, with V 4+ being the prevailing species at oxygen fugacities common for subduction zones (Sutton et al, 2005).…”

“…Hence, V can be an important factor for charge balance in rutile, but V valence states need to be better understood. A potentially powerful tool to assess valence states of V is partitioning between rutile, clinopyroxene, and garnet (Holycross and Cottrell, 2022), as rutile preferentially incorporates oxidised V species, while garnet and clinopyroxene prefer reduced V. Such partitioning data combined with the FTIR data on Ti 3+ and Fe 3+ in rutile might provide new avenues to constrain oxygen fugacity in metamorphic rocks.…”

Abstract. The coupling behaviour of H+ and trace elements in rutile has been studied using in situ polarised Fourier transform infrared (FTIR) spectroscopy and laser ablation inductively coupled plasma mass spectrometry (LA–ICP–MS) analysis. H2O contents in rutile can be precisely and accurately quantified from polarised FTIR measurements on single grains in situ. The benefits of this novel approach compared to traditional quantification methods are the preservation of textural context and heterogeneities of water in rutile. Rutile from six different geological environments shows H2O contents varying between ∼ 50–2200 µg g−1, with large intra-grain variabilities for vein-related samples with H2O contents between ∼ 500 and ∼ 2200 µg g−1. From FTIR peak deconvolutions, six distinct OH absorption bands have been identified at ∼ 3280, ∼ 3295, ∼ 3324, ∼ 3345, ∼ 3370, and ∼ 3390 cm−1 that can be related to coupled substitutions with Ti3+, Fe3+, Al3+, Mg2+, Fe2+, and Cr2+, respectively. Rutile from eclogite samples displays the dominant exchange reactions of Ti4+ → Ti3+, Fe3+ + H+, whereas rutile in a whiteschist shows mainly Ti4+ → Al3+ + H+. Trace-element-dependent H+ contents combined with LA–ICP–MS trace-element data reveal the significant importance of H+ for charge balance and trace-element coupling with trivalent cations. Trivalent cations are the most abundant impurities in rutile, and there is not enough H+ and pentavalent cations like Nb and Ta for a complete charge balance, indicating that additionally oxygen vacancies are needed for charge balancing trivalent cations. Valance states of multivalent trace elements can be inferred from deconvoluted FTIR spectra. Titanium occurs at 0.03 ‰–7.6 ‰ as Ti3+, Fe, and Cr are preferentially incorporated as Fe3+ and Cr3+ over Fe2+ and Cr2+, and V most likely occurs as V4+. This opens the possibility of H+ in rutile as a potential indicator of oxygen fugacity of metamorphic and subduction-zone fluids, with the ratio between Ti3+- and Fe3+-related H+ contents being most promising.

“…The ƒO2 influences key aspects of the SCLM such as melting, composition, speciation of volatiles (e.g., C, H, O) and multivalent elements (e.g., Fe, V, Cr), stability of C-bearing phases (diamond, graphite and carbonates), mineral/melt partitioning, degassing and metal fertility, as demonstrated by several studies (e.g., Mungall, 2002;McCammon and Kopylova, 2004;Frost and McCammon, 2008;Berry et a., 2013;Richards, 2015;Brounce et al, 2015;Yaxley et al, 2012Yaxley et al, , 2017Woodland and Seitz, 2018;Griffin et al, 2018;Aulbach et al, 2019;Tassara et al, 2020;Moretti and Neuville, 2021 and references therein). Most of the information about the redox evolution of the SCLM, ƒO2 mechanisms and distribution comes from experiments (e.g., Ballhaus et al, 1991;Holycross and Cottrell, 2022), quantification via proxies/oxybarometers in mantle-derived rocks such as mid-ocean ridge basalts and peridotites (e.g., V/Sc, Li and Lee, 2004;Lee et al, 2005; garnet and spinel oxybarometers, Miller et al, 2016) and modelling of element-…”
