Deep sourced fluids for peridotite carbonation in the shallow mantle wedge of a fossil subduction zone: Sr and C isotope profiles of OmanDP Hole BT1B

JC de Obeso, PB Kelemen, JM Leong… - Journal of …, 2022 - Wiley Online Library
Completely carbonated peridotites represent a window to study reactions of carbon‐rich
fluids with mantle rocks. Here, we present details on the carbonation history of listvenites …

Volatile-consuming reactions fracture rocks and self-accelerate fluid flow in the lithosphere

M Uno, K Koyanagawa, H Kasahara… - Proceedings of the …, 2022 - National Acad Sciences
Hydration and carbonation reactions within the Earth cause an increase in solid volume by
up to several tens of vol%, which can induce stress and rock fracture. Observations of …

Major mineral fraction and physical properties of carbonated peridotite (listvenite) from ICDP Oman Drilling Project Hole BT1B inferred from X‐ray CT core images
