Publikováno v: European Journal of Mineralogy, Vol 35, Pp 171-187 (2023)

Earth's long-term cycling of carbon is regulated from mid-ocean ridges to convergent plate boundaries by mass transfers involving mantle rocks. Here we examine the conversion of peridotite to listvenite (magnesite + quartz rock) during CO2 metasomati

Origin of Fe‐Ca‐Metasomatism in Exhumed Mantle Rocks at the MARK Area (23°N, ODP Leg 153) and Implications on the Formation of Ultramafic‐Hosted Seafloor Massive Sulfide Deposits

Publikováno v: Geochemistry, Geophysics, Geosystems, Vol 24, Iss 9, Pp n/a-n/a (2023)

Abstract At Mid‐Ocean Ridges, hot, reduced, acidic, and metal‐rich fluids are responsible for the formation of ultramafic‐hosted seafloor massive sulfide deposits (UM‐SMSs), where mantle exhumation efficiently operates. As UM‐SMSs display g

Progressive veining during peridotite carbonation: insights from listvenites in Hole BT1B, Samail ophiolite (Oman)

Autor: M. D. Menzel, J. L. Urai, E. Ukar, T. Decrausaz, M. Godard

Publikováno v: Solid Earth, Vol 13, Pp 1191-1218 (2022)

The reaction of serpentinized peridotite with CO2-bearing fluids to form listvenite (quartz–carbonate rock) requires massive fluid flux and significant permeability despite an increase in solid volume. Listvenite and serpentinite samples from Hole

Intracrystalline melt migration in deformed olivine revealed by trace element compositions and polyphase solid inclusions

Autor: V. Basch, M. R. Drury, O. Plumper, E. Hellebrand, L. Crispini, F. Barou, M. Godard, E. Rampone

Publikováno v: European Journal of Mineralogy, Vol 33, Pp 463-477 (2021)

Melt transport mechanisms have an important impact on the chemical composition of the percolated host rock and the migrating melts. Melt migration is usually assumed to occur at grain boundaries. However, microstructural studies revealed the occurren
