X-ray diffraction data for oxidized subsamples from the Escanaba Trough (Gorda Ridge)
This data release contains x-ray diffraction data of rock samples collected from the Escanaba Trough hydrothermal vent field, Gorda Ridge, in the northeast Pacific Ocean. These data were collected in 2022 on expedition TN403 (USGS Field Activity 2022-621-FA). Samples were taken to the USGS Pacific Coastal Marine Science Center for subsampling and x-ray diffraction analyses. Powder x-ray diffraction data for the rind layer of the rocks are provided in this dataset. Location information (latitude, longitude, depth) for each sample are provided in each Attribute Definition of this metadata file.
