Mesozoic granitic rocks in northwestern Nevada: A link between the Sierra Nevada and Idaho batholiths Mesozoic granitic rocks in northwestern Nevada: A link between the Sierra Nevada and Idaho batholiths
Extensive areas in northwestern Nevada are underlain by granodiorite and quartz monzonite plutons, as well as less common smaller bodies of quartz diorite. Twenty-six K/Ar age determinations on rocks from this suite range from about 175 to 85 m.y., but most of the plutons are between 105 and 85 m.y. old. This Late Cretaceous intrusive epoch extending from 105 to 85 m.y. ago is here named...
