Lithium isotopic composition of pore fluids and sediments in the Costa Rica subduction zone, supplement to: Chan, Lui-Heung; Kastner, Miriam (2000): Lithium isotopic compositions of pore fluids and sediments in the Costa Rica subduction zone: implications for fluid processes and sediment contribution to the arc volcanoes. Earth and Planetary Science Letters, 183(1-2), 275-290

Lui-Heung Chan & Miriam Kastner
Pore fluid and sediment Li concentrations and isotopic ratios provide important insights on the hydrology, sediment contribution to the arc volcanoes and fluid-sediment reactions at the dominantly non-accretionary Costa Rica subduction zone. Ocean Drilling Program Site 1039 in the trench axis provides a reference section of 400 m of the incoming sediments, and Site 1040, situated arcward from the trench, consists of a deformed sedimentary wedge and apron sediments, the décollement, and the partially dewatered...
