Abstract:

Whole rock geochemical analyses of nonfinite suite lavas sampled during IODP Expedition 352 at two sites: U1439C and U1442A. These sites lie in the Izu-Bonin forearc, NE of Chichijima (Bonin Island). The major elements and select trace elements analyzed the X-ray fluorescence spectrometry, other trace elements including the Rare Earth Elements (REE) analyzed by ICP-MS. CO2 was analyzed with a Costech Elemental Analyzer and used to correct major elements for secondary calcite content.

Comment:

† = XRF analyses normalized to 100%, BEFORE the calcite correction

CaO* = calculated CaO in silicate minerals after subtraction of CaO in Calcite (CaCO3)

FeO* = total iron as FeO

Fe2O3* = Total Iron as Fe2O3; XRF analyses normalized to 100%

Mg# = Molar Mg/(Mg+Fe), with Fe3+/Total Fe = 0.15
