4. • Based in ESRI ArcMap
• Uses PaleoGIS for creating plate reconstructions
• Plate reconstructions based on PLATES database
• Data for paleogeography based on CBTH database

5. • Compiled from
publications
• Georeference maps
and digitize well
locations
• Use a look-up table
with detailed
information for each
well

6. • Wells have individual
ID acting as table key
• General information
• Source
• Figure – link function
• Data shown

7. • Wells have individual
ID acting as table key
• General information
• Source
• Figure – link function
• Data shown

8. • Wells have individual
ID acting as table key
• For period or epoch
• Define if present
• Depth at bottom
• Depth at top
• Paleoenvironment
• Facies
• Description

9. • Compiled from
publications
• Georeference maps
and digitize sample
locations
• Use a look-up table
with detailed
information

10. • Information in the attribute table

11. • Age information
• From publication
• Formatted for
PaleoGIS

12. • Paleogeographic
maps from
publications
• Structural surfaces
from seismic
interpretation
• Georeference in
present-day

13. • Seismic lines are
digitized from
georeferenced maps
• SEGY Seismic lines
are interpreted

14. • Seismic facies are
classified
• Using the seismic
locations, facies are
mapped by age

19. • Be sure to take topology
into account
• Consider creating
polylines first and
converting to polygons
to avoid gaps and
overlaps
• After drafting and
checking, the lines can
be smoothed for more
artistic rendering of the
area
• Lines are converted to
polygons
• A consistent naming and
symbology system is
applied
