Ever since the late 1960s when Warren Hamilton proposed that the great Cordilleran batholiths of the western Americas are the roots of volcanic arcs like the...
Although widely used, classification schemes for granitic rocks have until now failed to separate slab failure from arc magmatism in collisional orogens. Our...
The Peninsular Ranges orogeny occurred during the mid-Cretaceous at _100 Ma and affected rocks from southern Mexico to Alaska. The event resulted from the...
The 1875-1840-Ma Great Bear magmatic zone is a 100-km wide by at least 900-km-long belt of predominantly subgreenschist facies volcanic and plutonic rocks that...
In the standard paradigm, continental crust is formed mainly by arc magmatism, but because the compositions of magma rising from the mantle are basaltic and...
The area includes Archean rocks of Slave craton and Paleoproterozoic rocks of Wopmay orogen. Both groups of rocks were deformed at 1.882 Ga during the...
The Leith Peninsula map area lies along the western margin of the Canadian Shield (Kidd, 1936a) and is dominated by Paleoproterozoic rocks of Wopmay Orogen...
Magmatism within the American Cordillera is commonly interpreted to have resulted from long-lived eastward subduction of Pacific oceanic lithosphere. However,...
In the standard model, Cordilleran-type batholiths form beneath volcanic arcs in thickened crust, but our survey of modern and ancient continental arcs...
