Analysis by Merril and by Eyerman in 1911.

Geochronology

Mineralization age: Proterozoic : 1292.4 ± 12.6 Ma to 985 ± 7 Ma

Important note: This table is based only on rock and mineral ages recorded below and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
