Dynamic Metasomatism Experiments Investigating the Interaction between Migrating Potassic Melt and Garnet Peridotite

Geosciences (Switzerland), 2021
Dynamic metasomatism experiments were performed by reacting a lamproite melt with garnet peridotite by drawing melt through the peridotite into a vitreous carbon melt trap, ensuring the flow of melt through the peridotite and facilitating analysis of the

Melt–rock interactions in a veined mantle: pyroxenite–peridotite reaction experiments at 2 GPa [PDF]

European Journal of Mineralogy, 2022
Interaction between peridotite and pyroxenite-derived melts can significantly modify the mineralogy and chemistry of the upper mantle, enhancing its heterogeneity, by creating re-fertilized peridotites and secondary-type pyroxenites.

Insight into drilling performance parameters for in-situ detection of lithological transition [PDF]

Scientific Reports
In order to examine the rock dependence on drilling performance parameters, such as torque and rate of penetration (ROP), we conducted laboratory drilling experiments using mafic and ultramafic rocks from the Oman ophiolite and the Horoman Complex ...

Atomic structure and physical properties of peridotite glasses at 1 bar

Frontiers in Earth Science, 2023
Earth’s mantle, whose bulk composition is broadly peridotitic, likely experienced periods of extensive melting in its early history that formed magma oceans and led to its differentiation and formation of an atmosphere. However, the physical behaviour of

Water in the Supra‐Subduction‐Zone Mantle of the Mariana‐Izu‐Bonin Forearc: Constraints From Peridotitic Orthopyroxene

Geochemistry, Geophysics, Geosystems, 2021
Orthopyroxene was analyzed as a proxy for water supra‐subduction‐zone peridotite by polarized infrared radiation. Samples from Conical and Torishima seamounts, Mariana‐Izu‐Bonin forearc (ODP‐Leg 125), have very similar average H2O contents of 215 ppm ...

Diamond and Other Exotic Mineral-Bearing Ophiolites on the Globe: A Key to Understand the Discovery of New Minerals and Formation of Ophiolitic Podiform Chromitite

Crystals, 2021
Ophiolite-hosted diamond from peridotites and podiform chromitites significantly differs from those of kimberlitic diamond and ultra-high pressure (UHP) metamorphic diamond in terms of occurrence, mineral inclusion, as well as carbon and nitrogen ...
