Supplemental Information

The DGGS metadata standard extends the FGDC standard to include elements that are required to facilitate our internal data management. These elements, referred to as "layers," group and describe files that have intrinsic logical or topological relationships. Attribute information for the layers (entity) is included in this metadata file under the "Entity_and_Attribute_Information" section. The layers are titled:
 >sample-location-details: A CSV file with sample location details, map and sample reference numbers, geographic location, latitude, longitude, and formation assignment.
 >raw-and-summary-data: An XLSX workbook providing raw and summary data. The spreadsheet is organized into the following tabbed worksheets: Table 2. Raw petrographic data in original format provided by Michael D. Wilson, Table 3. Raw petrographic data converted to format of Decker-Helmold, Table 4. Summary of petrographic data, Table 5. Grain size data in phi units, Table 6. Routine core analysis conducted by Weatherford Labs, Inc.


Metadata is the data about the data and answers "Who, what, when, where, how and why?" about the dataset. Please see the DGGS Metadata README page for information about our metadata.
