Abstract. The Penokean orogeny began at about Ma when an oceanic arc, now the Pembine-Wausau terrane, collided with the southern margin of the Archean Superior craton marking the end of a period of south-directed subduction.

The docking of the buoyant craton to the arc resulted in. Get this from a library. Structural geology of parautochthonous and allochthonous terranes of the Penokean orogeny in Upper Michigan: comparisons with northern Appalachian tectonics.

The evolution of the basin can be divided into an extensional stage with attendant deposition of stratified rocks, and a subsequent compressional stage assigned to the Penokean orogeny. The lower Proterozoic stratified rocks in the Animikie basin in Minnesota can be divided into two zones on the basis of pronounced differences in facies and.

for the Algoman Orogeny. Metadiabase intruded the gneiss in what appears to be a period of tension that effected the area about G.a. i G.a. Following this extensional phase came the compression and metamorphism of the Penokean Orogeny which partially reset the paleopoles in the gneiss and metadiabase and was dated by such at G.a.

The collision of two island arcs with the Superior Provinces produced the Penokean orogeny. The first island arc consisted mainly of volcanic and plutonic rock.

The arc was accreted along the Niagra fault that runs through western Minnesota, Wisconsin, and into central upper Michigan (Davis, 2). During the Penokean orogeny (1, to 1, million years ago), compression deformed the sequences in the Lake Superior region.
