Geologic setting

Geologic description

Syenite of the Kachauik pluton (Miller and others, 1972; Miller, 1972; Till and others, 1986) is anomalously radioactive adjacent to crosscutting alkaline dikes (Miller and others, 1976) here. The Kachauik pluton is a composite syenite, monzonite, granodiorite, quartz monzonite body that is mid-Cretaceous in age; a K/Ar age for the Kachauik pluton is 86.1 +/- 3 Ma (Miller and others, 1972).
