3. DATA REPORT: GEOCHEMICAL ANALYSES OF MASSIVE SULFIDE AND SEDIMENT SAMPLES FROM THE TAG HYDROTHERMAL MOUND1

D. Jay Miller2

ABSTRACT

Bulk-rock geochemical analyses were performed on 29 samples of massive sulfide and sulfide-bearing sediment from the TAG hydrothermal mound. This pilot study was intended to determine whether or not enrichments of platinum group elements could be detected within the mound deposits. Although significant enrichments of Au were detected from near the surface of the mound and in at least one sample from within the mound, Pt concentrations were below the detection limit of the analytical method used. Pd concentrations in all samples were near or below detection limits as well. These data are included in this volume to complement other bulk-rock analyses and petrographic descriptions.
