The reference to danalite at Levant Mine is a Kingsbury (1961) citation. Given the doubts about the provenance of other Kingsbury specimens (Ryback et al. 1998, 2001), further confirmation is required.

An extensive history of the mine is given in LEVANT by Cyril Noall.

Geochronology

Mineralization age: Late Triassic : 212 ± 4 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.
