The serpentinite multisystem revisited: chrysotile is metastable
BW Evans - International Geology Review, 2004 - Taylor & Francis
The two rock-forming polymorphs of serpentine Mg3Si2O5 (OH) 4, lizardite and chrysotile,
occur in nature in virtually identical ranges of temperature and pressure, from surficial or …

Pressure–temperature estimates of the lizardite/antigorite transition in high pressure serpentinites
Serpentine minerals in natural samples are dominated by lizardite and antigorite. In spite of
numerous laboratory experiments, the stability fields of these species remain poorly …

The role of serpentinites in cycling of carbon and sulfur: Seafloor serpentinization and subduction metamorphism
JC Alt, EM Schwarzenbach, GL Früh-Green… - Lithos, 2013 - Elsevier
We summarize the uptake of carbon and sulfur during serpentinization of seafloor
peridotites, and discuss the fate of these volatiles during subduction of serpentinite. We use …

Serpentine in active subduction zones
B Reynard - Lithos, 2013 - Elsevier
Serpentinization is a key phenomenon for understanding the geodynamics of subduction
zones in the 10–200 km depth range. Serpentines are a major water carrier, and their …

High abundances of noble gas and chlorine delivered to the mantle by serpentinite subduction
The Earth's mantle contains non-radiogenic noble gas isotopes that imply transfer of noble
gases from the atmosphere into the mantle through subduction. Hydrated serpentinite rocks …

The fate of B, Cl and Li in the subducted oceanic mantle and in the antigorite breakdown fluids
We present an inventory of B, Cl and Li concentrations in (a) key minerals from a set of
ultramafic samples featuring the main evolutionary stages encountered by the subducted …

Subducting serpentinites release reduced, not oxidized, aqueous fluids
The observation that primitive arc magmas are more oxidized than mid-ocean-ridge basalts
has led to the paradigm that slab-derived fluids carry SO2 and CO2 that metasomatize and …
