Abstract RECENT high-pressure experiments1–3 suggest that the Earth's lower mantle is
composed of MgSiO3 and CaSiO3 perovskites,(Mg, Fe) O magnesiowiistite, and a minor but …

Computational investigations, concerning structural, elastic, electronic, optical, and
thermometric properties of the MgLu 2 X 4 (X= S, Se) spinel compounds are performed. The …

An important role for the recycling of terrigenous sediments in the mantle was proposed by
Armstrong [1, 2]. Aspects of this hypothesis have been tested via an experimental study of …

We report in-situ petrological evidence of deep mantle origin from podiform chromitites in the
Luobusa ophiolite, southern Tibet. Analytical transmission electron microscopy …

An in situ Raman spectroscopic study was conducted to explore the pressure-induced
phase transformation of ferrite MgFe2O4 to 51.6 GPa. Results indicate that MgFe2O4 …

The ground-state crystal energies of cubic MgAl 2 O 4 (spinel) and MgO (periclase) and of
rhombohedral α-Al 2 O 3 (corundum) have been calculated at different volumes, relaxing the …
