Journal Article
George, F. R., Viete, D. R., Ávila, J., Seward, G. G., Guice, G. L., Allen, M. B., & Harrower, M. J. (2024). Garnet zoning patterns record multiple processes of chemical transfer during subduction. Earth and Planetary Science Letters, 631, Article 118634. https://doi.org/10.1016/j.epsl.2024.118634

Subduction is the principal mechanism by which volatiles are transferred from the Earth's surface to its interior. In garnets from eclogites and blueschists formed within the subduction setting, fine-scale, oscillatory elemental zoning is a common fe...
