How were the new test faults identified? (data sources and fault types)

GEMS Prize Challenge

Hello. Could we please ask three questions about data sources and fault types involved in identifying the new test faults? We’d like to have better insight into how they were identified, so we can choose appropriate input data and a sensible prediction density. Specifically:

  1. Data sources. Which data did the NLR and USGS experts use to identify the new faults? For example: GeoDAWN lidar, the 1 m 3DEP DEM, GeoDAWN magnetics or radiometrics, imagery, field mapping, or existing geologic maps.
  2. Fault types. Are the new faults mainly surface features, such as scarps and lineaments visible in topography? Or do they also include buried or inferred structures, interpreted from geophysics under basin fill?
  3. Coverage. Was the whole GeoDAWN region reviewed at a similar level of detail? Or were the new faults identified in selected parts of it?

Thank you!
