Abstract

The maximum concentrations of B and Li in bulk sediment, as well as their corresponding isotopic compositions, suggest uptake of both elements via chemisorption or secondary-mineral formation near the fluid conduit associated with the decollement zone. The low δ 11 B in pore waters suggests contribution of exchangeable plus lattice-bound B from greater depths. The corresponding high δ 6 Li similarly indicates mobilization from sediment under high-temperature conditions. -from Authors
