 | | The Penokean orogenic belt is a major early Proterozoic belt that is exposed in north-central Wisconsin. |
 | | Structural, stratagraphic, and magmatic assemblages of the orogen are typically viewed as the remnants of collision between Archean continental crust to the north (i.e., the Superior Province) and volcanic arc terrane(s) to the south (i.e., the Wisconsin magmatic terrane). |
