Title:
X-ray diffraction data (XRD) for sediment subsamples from push cores from Loki's Castle and Favne vent fields, Mohns Ridge
Abstract:
This portion of the data release presents X-ray diffractograms of sediment subsamples from push cores collected from Loki's Castle and Favne vent fields, on the Mohns Ridge, in the Norwegian Sea. These data were collected in 2018 and 2019 (USGS Field Activity 2018-691-DD and 2019-624-FA). Location information for the sample is included in each Attribute Definition of this metadata file, as well as in the geochemical data table (LokisMohns_marine_mineral_geochemistry.csv) of this multi-table data release.

    LokisFavne_XRD_rawdata.csv
    Comma-delimited file containing results from x-ray diffraction analyses of sediment subsamples from push cores. Location information for the samples is included in each Attribute Definition of this metadata file and not the data table. The header for each column of diffraction data is a sample name, which follows the scheme of ROV number followed by an underscore and then the sample number followed by an underscore and the centimeter range that the interval spans as counted from the surface of the sample.

Why was the data set created?

These data serve to expand the knowledge and statistics for deep ocean marine mineral occurrences and composition within the global ocean.

How was the data set created?

  1. From what previous works were the data drawn?
  2. How were the data generated, processed, and modified?
    Date: 04-Jul-2019 (process 1 of 4)
    Samples are push cores and were pushed into sediment by the ROV’s manipulator arm. Once recovered shipboard cores were frozen (2018-691-DD) or refrigerated (2019-624-FA) until return to shore. Samples were donated from Field Activity 2018-691-DD, and no USGS attendees were present. Amy Gartman attended 2019-624-FA.
    Date: 04-Jul-2019 (process 2 of 4)
    Back in the USGS lab, subsamples were collected from relevant stratigraphic regions of the core. Data sources produced in this process:
    • samples
    Date: 04-Jul-2019 (process 3 of 4)
    Powdered samples were backloaded and tamped into sample holders and run in a Panalytical X’Pert3 x-ray diffractometer (XRD; https://www.malvernpanalytical.com/) with CuK-alpha radiation and graphite monochromator. Measurements were taken at intervals of 0.2 degrees 2-theta between 4 degrees and 70 degrees 2-theta at 40 kilovolts and 45 milliamps. Data sources used in this process:
    • samples
    Data sources produced in this process:
    • results
    Date: 12-May-2023 (process 4 of 4)
    Results from the diffraction analyses were combined into a comma-delimited text values document (LokisFavne_XRD_rawdata.csv). Data sources used in this process:
    • results
  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
    X-ray diffraction data were tested for accuracy by analyzing a powdered quartz reference sample to verify the one hundred intensity peak at 26.6 degree two-theta. When the quartz peak was in the proper position, we infer that other measured peak positions in the sample are accurate. Peak intensities are considered semiquantitative since no quantitative standards were analyzed for this dataset.
  2. How accurate are the geographic locations?
    A formal accuracy assessment of the horizontal positional information in the dataset has not been conducted.
  3. How accurate are the heights or depths?
    A formal accuracy assessment of the vertical positional information in the dataset has not been conducted.
  4. Where are the gaps in the data? What is missing?
    Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.
  5. How consistent are the relationships among the observations, including topology?
    No formal logical accuracy tests were conducted.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
