Continental Evolution Processes: From Basins to Mountain Ranges

Explore the geologic evolution of continents from stable cratons to orogeny and mountain building stages involving magmatic differentiation, continental accretion, and plate collision. Witness the creation of new oceanic crust and the modification of continents through the Wilson Cycle. Delve into the formation of volcanic island arcs, continent collisions, and the growth of coastal plains and continental shelves. Understand the geological history of Virginia as a prime example of continental evolution.
