We report two groups of fluid inclusions in carbonates in veined serpentinites in Oman ophiolite complex previously studied by Noël et al. (2018, Lithos): saline fluids (2.7% NaCl) in type 1 carbonates that were formed through submarine hydrothermal alternation, and pure water (0.1% NaCl) in type 2 and 3 carbonates that were formed through continental alternation processes.
