Living at the extremes: extremophiles and the limits of life in a planetary context
Prokaryotic life has dominated most of the evolutionary history of our planet, evolving to
occupy virtually all available environmental niches. Extremophiles, especially those thriving …

Aqueous fluids and hydrous melts in high-pressure and ultra-high pressure rocks: implications for element transfer in subduction zones
High-pressure (HP) and ultra-high pressure (UHP) terranes are excellent natural
laboratories to study subduction-zone processes. In this paper we give a brief theoretical …

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

Serpentine in active subduction zones
B Reynard - Lithos, 2013 - Elsevier
Serpentinization is a key phenomenon for understanding the geodynamics of subduction

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 …
