Quantifying the volume increase and chemical exchange during serpentinization

, 2020
Quantifying the concurrent changes in rock volume and fluid composition during serpentinization remains a major challenge in assessing its physicochemical effects during continental rifting, seafloor spreading, and subduction.

Pore fluid effects on elastic wave velocities of serpentinite and implications for estimates of serpentinization in oceanic lithosphere

, 2020
Recent seismic refraction surveys at various outer-rise regions have identified low seismic velocities in the uppermost mantle, which is indicative of mantle hydration (serpentinization) related to water infiltration along bending-related faults prior to

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.

The production of iron oxide during peridotite serpentinization: Influence of pyroxene

Geoscience Frontiers, 2017
Serpentinization produces molecular hydrogen (H2) that can support communities of microorganisms in hydrothermal fields; H2 results from the oxidation of ferrous iron in olivine and pyroxene into ferric iron, and consequently iron oxide (magnetite or ...

A search for minerals associated with serpentinization across Mars using CRISM spectral data

Icarus (New York, N.Y. 1962), 2018
Sites associated with serpentinization processes, both on Earth and throughout the Solar System, are becoming increasingly compelling for the study of habitability and astrobiology. The co-occurrence of serpentine, Mg-carbonate, and talc/saponite on Mars

In-situ oxygen isotope analyses in serpentine minerals: Constraints on serpentinization during tectonic exhumation at slow- and ultraslow-spreading ridges

Lithos, 2018
Peridotites exhumed along detachment faults at slow- and ultraslow-spreading ridges undergo variable and complex serpentinization. Here, we present in-situ oxygen isotope analyses in serpentine minerals from a textural sequence identified in samples ...
