... into quartz veins along strike. The diorite suite (95.4–93.7 Ma) consists of small stocks of diorite to tonalite that intrude the older suites and are inferred to intrude the shallowly dipping auriferous quartz veins. Limited data indicate granitoid emplacement at 5–9 km depths, consistent with formation...

Argon plateau ages of 88.1 to 86.8 Ma have been determined for muscovite from selvages of the sheeted auriferous veins ( McCoy et al., 1997 ). Thus, the existing age data suggest a potential age range of ∼6 m.y. for gold vein formation at Fort Knox...

.... In this study, there is little evidence of active volcanism in the source region; thus the FT ages reflect cooling during denudation of the source regions. The oldest sample in our suite, from the upper Eocene Lyre Formation, shows a dominant peak at ca. 40 Ma, coincident with cooling ages of denuded...
