Data Report: Major and trace element geochemistry of shipboard samples from Site 957, TAG hydrothermal field, Mid-Atlantic Ridge

Representative samples of drill core were collected from each of the five main areas drilled on the TAG (Trans-Atlantic Geotraverse) mound during Leg 158 (Humphris, Herzig, Miller, et al., 1996). In this report, we present the results of chemical analyses of 66 samples previously analyzed for Cu, Fe, Zn, Pb, Ag, and Cd by atomic absorption during Leg 158. Data are presented for an additional 38 elements plus total sulfur, loss on ignition, and the rare earth elements by a combination of optical emission spectrometry (ICP-ES), mass spectrometry (ICP-MS), and neutron activation (INAA). These data are discussed in detail in other chapters in this volume.
