"Geological map of the world classifies continental regions by geologic province and oceanic crust by age. Geologic provinces include shield, platform, orogen, basin, large igneous province, and extended crust, distributed across the continents. Oceanic crust is grouped into 0 to 20, 20 to 65, and greater than 65 million years, with older crust generally farther from mid-ocean ridges."
