Information on seismic anisotropy in the Earth's mantle can be obtained from (1) shear-wave splitting analyses which allow to distinguish single or multi-layered and delay time of fast slow polarized wave indicate its thickness, (2) studying peridotites where properties inferred lattice preferred orientation deformed minerals. We provide a detailed map western part Carpathian-Pannonian region (...

New geochemical data were presented for the mafic (basalts and gabbros) ultramafic (dunites, serpentinites pyroxenites) rocks from Mawat ophiolite exposed in Zagros suture zone northeastern Iraq. The mantle section of is composed serpentinized peridotites, harzburgites, dunites, chromitites pyroxenite dykes. crustal layered amphibole-rich gabbros, pegmatitic gabbros as well basalts minor felsic...

Pyroxene is the chief reservoir of Fe 3+ in upper mantle peridotite, but experiments exploring pyroxene/melt partitioning ( D Fe3+ pyx/liq ) have been restricted to 100 kPa and pyroxene with low alumina. Here we present between clinopyroxenes (cpx) mafic melt at elevated pressures (1–2.5 GPa). Experiments were conducted f O2 buffered modulated by Ru + RuO 2 Fe-Pt alloy capsules, respectively, Δ...

Mantle–melt interaction during melt transport is explored in one generally moves relative to the residual solid phases. This follows from experimental and theoretical studies of the dimension and steady state. We reconsider the equivalence between one-dimensional steady equilibrium transport and batch melting. In equilibrium textures of olivine-dominated, partially molten systems, which indicat...

Introduction: Studies of terrestrial peridotite and martian and achondritic meteorites have led to the conclusion that addition of chondritic material to growing planets or planetesimals, after core formation, occurred on Earth, Moon, Mars, asteroid 4 Vesta, and the parent body of the angritic meteorites [1-4]. One study even proposed that this was a common process in the final stages of growth...
