Global Craton Geometry
Cratons are commonly studied individually, yet their global distribution also represents a measurable geometric dataset.
Regional Geological Context
Major cratonic provinces occur across Australia, Canada, Brazil, South Africa, Greenland, India, Antarctica, and China.
Observation
The spatial distribution of surviving cratons is not uniform across Earth's surface.
Open Questions
Does the modern distribution of ancient cratons preserve information regarding earlier planetary organization?
