Tin-bearing magnetite with nanoscale Mg-Si defects: Evidence for the early stages of mineralization in a skarn system

Frontiers in Earth Science, 2023
Tin-bearing magnetite is reported from several types of magmatic-hydrothermal ore deposits. The question of whether tin is incorporated within solid solution, as Sn4+, or as nanoinclusions remains open, however.

Si Isotope Fractionation in Metamorphic Rocks From Cryogenic Temperature Crystallographic Data and Quantum Phonon Model

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract In this study, we demonstrate that it is possible to fit the resilience at the high temperature limit using only the atomic mean square displacement determined from cryogenic temperature single crystal diffraction data. Our method introduces the Debye phonon model, under which the atomic mean square displacement displays quantum behavior at ...

Carbonic Fluids Drive Continental Carbon Cycling as Revealed by the Geochemistry of the Eclogite‐Garnet Peridotite Interface

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Subduction zones regulate Earth's carbon distribution, yet the mechanism of carbon transfer from continental crust to mantle remains elusive. We examined an eclogite‐garnet peridotite interface from the Chinese Continental Scientific Drilling Program in the Sulu orogen, representing the slab–mantle wedge boundary formed during continental ...

Provenance Reassessment of Eocene Turbidites, New Caledonia: Inferences for Obduction Models

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Provenance of pre‐obduction Eocene turbidites from New Caledonia is used to better constrain their geodynamic context and inform debate on subduction polarity. Chemical compositions of detrital clinopyroxenes in arenites are compared against potential sources.
