Геодинамика и тектонофизика, 2018 Ancient primary boninitic melts of the Gorny Altai (65–105 km, 1410–1590 °C) were studied from the composition of melt inclusions in clinopyroxenes.

Creep of dry clinopyroxene aggregates [PDF]
Journal of Geophysical Research: Solid Earth, 2001 We have determined diffusional and dislocation creep rheologies for clinopyroxenite Ca1.0Mg0.8Fe0.2Si2O6 under dry conditions by deforming natural and hot‐pressed samples at confining pressures of 300–430 MPa and temperatures of 1100°–1250°C with the oxygen fugacity buffered by either nickel‐nickel oxide or iron‐wüstite powders.

Clinopyroxene/melt trace element partitioning in sodic alkaline magmas [PDF]
, 2019 Clinopyroxene is a key fractionating phase in alkaline magmatic systems, but its impact on metal enrichment processes, and the formation of REE + HFSE mineralisation in particular, is not well understood. To constrain the control of clinopyroxene on REE +

The effect of fluorine on clinopyroxene/melt trace-element partitioning
, 2020 International audienceThe impact of fluorine on phase relations and clinopyroxene-melt element partitioning has been explored experimentally to better understand the effect of this halogen on the residual enrichment of the REE and HFSE during ...

The Role of Clinopyroxene on the Rheology of Dry Olivine–Clinopyroxene Aggregates
MineralsTo investigate the influence of a second-phase mineral on the rheology of mantle peridotite, we conducted high-temperature deformation experiments on dry olivine–clinopyroxene (Ol-Cpx) aggregates. Cylindrical samples were manufactured using hot-isostatic pressing techniques, with Ol as the matrix phase and Cpx added at volume fractions of fCpx = 0.1, 0.

The Late- Cretaceous volcanic rocks from Talesh area (western Alborz): chemical variation, crystallization condition, hygrometry and tectonic setting [PDF]
پترولوژی, 2020 In the Talesh area (western Alborz), a thick sedimentary- volcanic association formed in a littoral- deltaic environment during the Late Cretaceous. The extrusives comprise volcanoclastics (tuffs), lava flows (pillow and massive) and basic dykes.
