The thermodynamic behavior of calcium oxide (CaO) under high temperature and pressure conditions is critical for understanding the physics of planetary interiors. This study employs molecular dynamics (MD) simulations, including both classical and ab initio approaches, to investigate the melting behavior of CaO. We calculate the melting...

Thermal convection in the Earth's mantle is driven by lateral variations in temperature and density which are substantially controlled by the local volume thermal expansion of the constituent mineral phases. Ringwoodite is a major component of the lower mantle transition zone, but its thermal expansivity and thermoelastic properties are still...

The new mineral species arsenmedaite, ideally Mn2+As5+Si5O18(OH), has been discovered in quartz veinlets in the braunite ore deposit of the Molinello mine, Graveglia Valley, Ne, Genova, Liguria, Italy. It occurs as orange-reddish prismatic crystals, up to 200 lm in length, with a vitreous lustre, associated with braunite, quartz, calcite,...

In questo lavoro viene fornito un quadro aggiornato, per quanto non esaustivo, di alcuni ritrovamenti mineralogici significativi effettuati nelle rodingiti alpine e appenniniche della Liguria nell'ultimo cinquantennio. Oltre ad una rinnovata documentazione fotografica di campioni "classici" di granato, vesuvianite, titanite, etc., viene...

This research investigates the high-pressure behavior of the Ca(Ti0.95Ge0.05)O3 perovskite, a candidate of the locked-tilt perovskite family (orthorhombic compounds characterized by the absence of changes in the octahedral tilt and volume reduction under pressure controlled solely by isotropic compression). The study combines experimental...

Ramazzoite (IMA2017-090), [Mg8Cu12(PO4)(CO3)4(OH)24(H2O)20][(H0.33SO4)3(H2O)36], is a new polyoxometalate (POM) mineral from the Monte Ramazzo mine, near Genova, Liguria, Italy. It occurs on magnetite-rich matrix in association with chlorartinite, chrysotile, dypingite, goethite, lepidocrocite and nesquehonite, and is a late-stage, secondary...

New ReaxFF parameters are developed for the description of Mg/Al/Si/O interaction for the Magnesium Aluminosilicate (MAS) glass structure. The training set contains energy curves from equation of state for various Mg/Al/Si/O crystals, valence angle and bond distance scan, and heat of formation for the Mg/Al/Si/O interactions. A semi-automated...

The subduction of oceanic slabs with diverse lithologies greatly contributes to the geochemical heterogeneity of the mantle. Oceanic metasomatism leads to the formation of rocks with heterogeneous geochemical characteristics, which can be further modified by fluid–rock interactions during subduction zone processing. Investigations of exhumed...
