All Terranes and Suture Zones

This group collects the Structural and Tectonic Formations subcategory's members that are terranes and suture zones, fragments of crust with a distinct geological history that have been accreted onto a larger continental mass, and the sutures marking where separate ancient landmasses collided and joined. These are among the more specialized and less numerous feature types in this subcategory, tracing the deep history of how today's continents were assembled from smaller pieces over hundreds of millions of years.
