- Abstract:
- The extent to which heat is directly extracted from the lower (plutonic) ocean crust by hydrothermal circulation is unknown. This is problematic both for models of magmatic accretion of the lower crust, which are dependent on the location of latent heat loss, and for estimates of hydrothermal fluxes at mid-ocean ridges. Uncertainties in the latter are caused by the likelihood that fluid-flow in the lower ocean crust will be more channelised than that in the upper crust. This means that removal of a given amount of heat from the lower crust may be associated with a much smaller mass flux than the same heat removal by hydrothermal circulation within the upper crust. These issues will be addressed using a combined study of the variation in cooling rate, and of chemical-tracers (principally O- and Sr-isotopes) in and around conduits for focused fluid-flow in the Oman ophiolite.
