Data package

Here we report the full dataset used for the manuscript 'Tracing the Scale of Fluid Flow in Subduction Zone Forearcs: Implications from Fluid-Mobile Elements' submitted to the journal Chemical Geology. The reader is referred to the Methods section for a detailed description of the analytical protocols. Contents of the file Table A.1. Sample locations, pressure-temperature estimates based on Raman Spectroscopy of Carbonaceous Material and multi-phase equilibrium model, and salinity of fluid inclusions in vein samples. Table A.2. Whole-rock major and trace element composition of metapelites from the Kodiak Complex and the Shimanto Belt, as well as values of duplicates, blank, and standards. Table A.3. LA-ICP-MS analyses of reference material used for calibration and to monitor the data quality. Table A.4. Trace element concentrations in illite (ill), albite (ab), chlorite (chl), and vein calcite (Cc) determined by LA-ICP-MS. Table A.5. Chemical composition of fluid inclusions analyzed by LA-ICP-MS and semi-quantified by the charge-balance approach. Figure A.1. Transient LA-ICP-MS signals of analyzed elements in FI-poor and FI-rich areas of quartz.
