Eleven small Mesozoic plutons crop out within a 76-squaremile
area of the southern Seven Devils Mountains in west-central
Idaho. The plutons are divided into a mafic suite, an older granitic
suite, and a younger granitic suite on the basis of age, lithology, and
degree of metamorphism.
The six plutons of...
