Subducted carbonates , metasomatism of mantle wedges , and possible connections to diamond formation : An example from California

  title={Subducted carbonates , metasomatism of mantle wedges , and possible connections to diamond formation : An example from California},
  author={Mihai N Ducea and Jason B. Saleeby and Jean Morrison and Victor A. Valencia},
We investigated calcite globules and veins in two spinel-garnet peridotite xenoliths from the subSierra Nevada mantle. The studied xenoliths were entrained in a Miocene (11 Ma) volcanic plug. These carbonates are associated spatially with silicate glass inclusions, suggesting that they are primary inclusions—inclusions that formed at high temperature in the mantle and not at or close to the Earthʼs surface. The host peridotites represent samples of the lithospheric mantle wedge beneath the… CONTINUE READING
