- 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.
