Three steps of serpentinization in an eclogitized oceanic serpentinization front (Lanzo Massif – Western Alps)

Journal of Metamorphic Geology, 2013
International audienceThe Lanzo peridotite massif is a fragment of oceanic lithosphere generated in an ocean-continent transition context and eclogitized during alpine collision.

Effect of pressure on the kinetics of peridotite serpentinization

Physics and Chemistry of Minerals, 2020
The kinetics of serpentinization were investigated at 400-500 degrees C and 3.0-20 kbar using natural olivine and peridotite for run durations of 9-38 days. The serpentine varieties were lizardite for all the experiments. The serpentinization kinetics at

Mass transfer in the oceanic lithosphere: Serpentinization is not isochemical

Earth and Planetary Science Letters, 2015
Whereas the serpentinization reaction leads to stark differences in the physical properties of mantle rocks at mid-ocean ridges, the chemical changes associated with this reaction are thought to be restricted to the addition of water and the generation ...

Serpentinization as a reactive transport process: The brucite silicification reaction

Earth and Planetary Science Letters, 2018
Serpentinization plays a fundamental role in the biogeochemical and tectonic evolution of the Earth and perhaps many other rocky planetary bodies. Yet, geochemical models still fail to produce accurate predictions of the various modes of serpentinization,

Influence of pH on Molecular Hydrogen (H2) Generation and Reaction Rates during Serpentinization of Peridotite and Olivine

Minerals (Basel, Switzerland), 2019
Serpentinization produces molecular hydrogen (H2) that is capable of supporting communities of microorganisms in hydrothermal fields, which suggests that serpentinization may be closely related to the origin of life at the early history of the Earth and ...

Controls of faulting and reaction kinetics on serpentinization and double Benioff zones [PDF]

Geochemistry, Geophysics, Geosystems, 2012
The subduction of partially serpentinized oceanic mantle may potentially be the key geologic process leading to the regassing of Earth's mantle and also has important consequences for subduction zone processes such as element cycling, slab deformation ...

Serpentinous leiomyoma uteri

American Journal of Obstetrics and Gynecology, 1962
Abstract 1. Leiomyoma of the uterus with serpentinous arrangement of nuclei of smooth muscle is presented. 2. The term “serpentinous leiomyoma uteri” is proposed for this morphologic picture. 3. The etiology and histogenesis of this morphologic pattern remain obscure.
