About this source

Macrostrat geologic database - stratigraphic columns, formation data, and geologic units. Query surface geology, get stratigraphic columns, and look up formation details. Useful for understanding subsurface geology for oil & gas exploration. CRITICAL USAGE RULES: 1. No authentication required 2. Use getGeologyAtPoint() for surface geology at a location 3. Use getStratColumn() for the full stratigraphic column 4. Use getFormationInfo() to look up formations like "Wolfcamp", "Bakken"

Caveats

  • ⚠ Point and column lookups can legitimately return no records where Macrostrat has no coverage.
  • ⚠ Name searches are fuzzy and may return the same formation from multiple regional columns.

› Methods (4)

Technical detail for developers: parameters, pagination, units, and freshness per method.

  • getGeologyAtPoint

    read

    Return surface geologic map units at one WGS84 latitude/longitude. Use this for what is mapped at a location, not a complete subsurface column.

  • getStratColumn

    read

    Return each Macrostrat column covering one WGS84 coordinate, including the full ordered unit list for every returned column.

    Entitiesstratigraphic column, stratigraphic unit
    Paginationnone
    FreshnessScheduled (source-level)

  • searchUnits

    read

    Fuzzy-search Macrostrat units by stratigraphic name. Returns at most 25 matches by default; pass limit from 1 to 100.

    Paginationnone
    FreshnessScheduled (source-level)
    • ⚠ Fuzzy matches may contain the same named formation in multiple regional columns; results are capped at the requested limit.

  • getFormationInfo

    read

    Look up detailed Macrostrat unit records by fuzzy stratigraphic formation name. Returns at most 25 matches by default; pass limit from 1 to 100.

    • ⚠ A formation can have several records because Macrostrat stores it in multiple regional columns; results are capped at the requested limit.
