Formation of olivine veins by reactive fluid flow in a dehydrating serpentinite

Abstract

Serpentinites represent the major fluid source within subducting oceanic plates and carry large amounts of water, stored in hydrous minerals, into subduction zones worldwide (e.g., Rüpke et al., 2004;Scambelluri et al., 1995;van Keken et al., 2011). Fully hydrated oceanic mantle can store up to 13 wt. % water, which is released in a series of dehydration reactions (e.g.,
