The Paleozoic evolution of Patagonia was the focus of controversies between its allochthonous or autochthonous origin. The arrival of plate tectonics supported new allochthonous alternatives and from an initial fixist resistance, different mobilistic hypotheses have made their way. There is currently some consensus about its allochthony, but there is no agreement on collision times …

The western Idaho suture zone (WISZ) and the 87Sr/86Sr = 0.706 isopleth sharply demark the boundary between cratonic North America to the east and Paleozoic and younger accreted oceanic terranes to the west; the boundary becomes diffuse in northern Nevada owing to superimposed Neogene Basin and Range extension.

1. Introduction [2] Despite extensive research over the last ∼100 years in the northern Basin and Range Province [e.g., Emmons, 1907], its northwestern margin remains little-studied.This region is characterized by a transition from Basin and Range extension in northwestern Nevada to high volcanic plateaus in northwesternmost Nevada, northeastern California, and southern Oregon.

Exercise: 1 Instructions: Most of the rock west of the Idaho batholith was formed from oceanic or island arc assemblages. These rocks were accreted or pressed to North America between the Late-Triassic and the Mid-Cretaceous time. This means that before Jurassic time, the West Coast of North America was situated near Riggins, Idaho.
