Geosciences, 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

Water in Hawaiian peridotite minerals: A case for a dry metasomatized oceanic mantle lithosphere
Geochemistry, Geophysics, Geosystems, 2015 The distribution of water concentrations in the oceanic upper mantle has drastic influence on its melting, rheology, and electrical and thermal conductivities and yet is primarily known indirectly from analyses of OIB and MORB.

Global variations in abyssal peridotite compositions
Lithos, 2016 Abyssal peridotites are ultramafic rocks collected from mid-ocean ridges that are the residues of adiabatic decompression melting. Their compositions provide information on the degree of melting and melt–rock interaction involved in the formation of ...

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.

Weakening of Peridotite Sheared at Hydrothermal Conditions
Geochemistry, Geophysics, Geosystems, 2021 We conducted triaxial friction tests at hydrothermal conditions (25°C–350°C) on gouges of peridotite and its principal mineral constituents olivine and orthopyroxene. Pore‐fluid chemistry was varied by the use of peridotite, granite, or quartzite driving

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

In situ carbonation of peridotite for CO2 storage
Proceedings of the National Academy of Sciences of the United States of America, 2008 The rate of natural carbonation of tectonically exposed mantle peridotite during weathering and low-temperature alteration can be enhanced to develop a significant sink for atmospheric CO2.
