| Abstract |
Funds that are provided will extend the use of the Lithium proxy
to the arc systems. The objectives are to determine the isotopic
variaion of Lithium in lavas as a funciton of the nature of subarc
mantle, the extent of modification by subduction components, the
mass transfer processes and the physical conditions of the subduction
environment. In addition, sediment flux carried by the down-going
plate will also be estimated to assess lithium recycling at the
convergent margins. Samples from the Cascadia, Aleutian and Tonga-Kermadec
Arcs will be analyzed. |
