Geologic units containing peraluminous granite

California

Cenozoic (Tertiary) granitic rocks? (Skidoo Pluton) (Early to Late Cretaceous)

Cenozoic (Tertiary) granitic rocks--quartz monzonite, quartz latite, and minor monzonite, granodiorite, and granite; found in the Kingston, Panamint, Amargosa, and Greenwater Ranges in southeastern California(?)

Idaho

Felsic augen gneiss after porphyritic granite; Middle Proterozoic; southern Belt province (Middle Proterozoic)

Augen gneiss, amphibolite and other metamorphosed igneous rocks; possibly Precambrian.

Granodiorite and muscovitic monzogranite; Oligocene Almo pluton; south-central Idaho, Albion Range metamorphic core complexIdaho (Oligocene)

Oligocene granodiorite to muscovite pegmatite, pegmatitic granite, and mylonitized granitic injection gneiss

Intrusive rocks: mostly Late Cretaceous granodioritic to granitic plutons of the Idaho batholithic assemblage, but including some Eocene intrusions; northern Idaho and Atlanta batholith (Cretaceous to Eocene)

Cretaceous plutons; probably includes unmapped older and younger crystalline bodies.

Peraluminous monzogranite, granodiorite, pegmatite, aplite, and migmatite; mostly Cretaceous intrusions of the Kaniksu batholithic assemblage, but with minor Eocene intrusions, undivided; northern Idaho (Cretaceous to Eocene)

Cretaceous plutons; felsic; as granite or quartz monzonite; probably includes unmapped older and younger crystalline bodies.
