Seismogenic Consequences of COH‐Fluid Rock Interactions in Ultramafic Fault Zones Insights From Carbonation‐Decarbonation Friction Experiments

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Fluid‐rock interactions have major implications on the frictional behavior of fault rocks. Infiltration of CO2‐bearing fluids in ultramafic fault zones causes the progressive formation of serpentinite, talc‐magnesite (soapstone) and quartz‐magnesite (listvenite) assemblages.

Sintering polycrystalline olivine and polycrystalline clinopyroxene containing trace amount of graphite from natural crystals

Earth, Planets and Space, 2017
Graphite-bearing polycrystalline olivine and polycrystalline clinopyroxene with submicron to micron grain size were successfully sintered from a single crystal of naturally occurring olivine (Fo88–92Fa12–8: Mg1.76–1.84Fe0.16–0.24SiO4) and a single ...

A Graphical User Interface Application to Model Open‐System Melting in the Upper Mantle

Geochemistry, Geophysics, Geosystems
The mantle partial melting process is crucial for the physicochemical evolution of the Earth's upper mantle and the generation of mafic crust. The open‐system melting model incorporates continuous melt segregation, interaction with melts or fluids, and ...

Clinopyroxene precursors to amphibole sponge in arc crust [PDF]

Nature Communications, 2014
AbstractThe formation of amphibole cumulates beneath arc volcanoes is a key control on magma geochemistry, and generates a hydrous lower crust. Despite being widely inferred from trace element geochemistry as a major lower crustal phase, amphibole is neither abundant nor common as a phenocryst phase in arc lavas and erupted pyroclasts, prompting some ...

Distinctive Crystal-chemistry and Site Configuration of the Clinopyroxene From Alkali Basaltic Rocks - the Nyambeni Clinopyroxene Suite, Kenya

, 1986
A crystal chemical investigation of clinopyroxenes from a suite of nepheline-bearing lavas located in the Nyambeni Range of Kenya has delineated the polyhedral site configurations and related intracrystalline relationships.

Comparative compressibility of clinopyroxenes from mantle nodules

European Journal of Mineralogy, 1995
The comparative compressibilities of two clinopyroxenes from mantle nodules were determined by single crystal X-ray diffraction with a Merrill-Bassett diamond anvil cell. The analysed crystals show different chemical compositions: PC 135, from a spinel lherzolitic nodule from Pico Cabugi, NE Brazil, has more R3+ (Fe3+ + VIA1 + Ti + Cr) in the Ml site ...
