Abstract

Heat transfer processes at the mounds area of the Galapagos Spreading Center at 86oW are revealed by temperatures measured at approx 10m intervals in the 30+ or -10m sediment at each of 12 holes at DSDP Leg 70 Sites 506-509 and by temperatures of up to five thermistors on eleven 8-12m long piston cores. The 325 needle- probe values show a significant linear increase of thermal conductivity with depth in each core. About half of the temperature-thermal resistance profiles are nonlinear and are fit to a steady state, vertical pore water advection model. Results indicate high and variable total heat flow and localized hydrothermal discharge at approx 10-8m/s, associated with individual mounts. Recharge is indicated at similar rates in the low heat flow belt approx 5km S of the mounds and is suggested at slower rates in the intermediate heat flow (0.17-0.42 W/m2) belt surrounding the mounds heat flow high. Possible slow entrained recharge within approx 100m of discharging mounds is suggested.-Authors
