Map of world geologic provinces
   Shield
   Platform
   Orogen
   Basin
   Large igneous province
   Extended continental crust

Oceanic crust:

   0–20 Ma
   20–65 Ma
   >65 Ma


These geologic province maps depict only features approximately 150 km across and greater due to the fact that the resolution of the maps should be consistent with the resolution of the seismic refraction data.
