The Spavinaw terrane is an occurrence of Proterozoic (1.40–1.35 Ga) [1] intrusive and volcanic rocks in the mid-continent region of the United States.The terrane extends across southern Missouri, southern Kansas, northern Arkansas and much of Oklahoma.
A tectonostratigraphic terrane is a fault-bounded package of rocks of at least regional extent characterized by a geologic history that differs from that of neighboring terranes. The essential characteristic of these terranes is that the present spatial relations are incompatible with the inferred geologic histories.
Other Mesozoic terranes that accreted onto the continent include the Klamath Mountains, the Sierra Nevada, and the Guerrero super-terrane of western Mexico. [42] 80 to 90 million years ago the subducting Farallon plate split and formed the Kula Plate to the North. [32] Many of the major batholiths date from the late Cretaceous. [42]

The extent of the formation is unclear; some geologists believe that a magnetic anomaly along the coast of Cape Cod may represent a suture between the Meguma and Avalon terranes in that region. [4] Unlike the Avalon terrane, the Meguma terrane has not been definitely associated with a territory on the other side of the Atlantic.

Rather than being a single block, there were apparently two groups of blocks, the European Hunic terranes and the Asian Hunic terranes. [ 1 ] [ 2 ] [ 3 ] The collision with Laurasia (specifically, with the Kipchak arc ) formed what is now known as Kazakhstania according to one geological model of the ancient Earth.
