    en.wikipedia.org/wiki/List_of_shields_and_cratons

    Cratons whose ancient rocks are widely exposed at the surface, often with relatively subdued relief, are known as shields. If the ancient rocks are largely overlain by a cover of younger rocks then the 'hidden' craton may be referred to as a platform .

    Cratons are the oldest and most stable parts of the continental lithosphere, and shields are exposed parts of them. Terranes are fragments of crustal material formed on one tectonic plate and accreted to crust lying on another plate, which may or may not have originated as independent microplates: a terrane may not contain the full thickness of ...

    [41] [4] [38] For example, Zhu proposes that the subduction of Paleo-Pacific Ocean was a retreating subduction system, that caused the lithospheric thinning in the Cretaceous. [ 4 ] [ 38 ] [ 41 ] Collapse of orogen introduces a series of normal faults (e.g. bookshelf faulting) and thinned the lithosphere. [ 33 ]
