Geochemistry and x-ray diffraction data for hydrothermal manganese oxide rocks from the Samoa hotspot region in the South Pacific Ocean collected during research expedition KM0506
Abstract
Hydrothermal manganese oxide rocks were collected via dredge from the Tulaga Seamount, the flank of Ofu Island, and from Soso seamount in the Samoa hotspot region offshore American Samoa during the KM0506 cruise aboard the R/V Kilo Moana in April of 2005. Rocks were subsampled at USGS and analyzed for mineralogy by x-ray diffraction as well as sent to SGS laboratories, Canada for major and trace element geochemistry.
