Reactive porous or focused melt flows are common in crystal mushes of mid-ocean ridge magma reservoirs. Although they exert significant control on magmatic differentiation, their role metal transport between the mantle and ocean floor remains poorly constrained. Here we aim to improve such knowledge for oceanic crust formed at slow-spreading centers (approximately half present-day crust), by fo...

To investigate the influence of hydration on brittle deformation oceanic crustal rocks, we conducted triaxial experiments gabbroic rocks with various degrees at a confining pressure 20 MPa and room temperature, measuring elastic wave velocity. Hydrated olivine gabbros reached maximum differential stress 225–350 MPa, which was considerably less than those recorded for (~450 MPa), but comparable ...

The Oman Ophiolite is regarded as an analogue to modern fast-spreading ocean ridge systems in environment of subduction zone initiation. In contrast recent mid-ocean basalts from the East Pacific Rise, parental melts at paleoridge are assumed be hydrous nature. order constrain role water during magmatic accretion processes deep crust paleoridge, we evaluated several experimental studies tholeii...
