Alkaline complex-hosted gold deposit, occurring in the inner contact zone of an alkaline syenite that is overprinted by faults and fractures. The deposit is irregular and is concordant to the strike of the contact zone and the faults. Four deposition stages occur: (1) molybdenite-quartz, (2) quartz-pyrite, (3) base metallic sulphide, and (4) carbonate. Alteration includes epidote, chlorite, sericite, pyrite, and carbonate alterations. The gold deposition is interpreted as related to the shearing of the Archean Wulashan Group of metamorphic rocks. The deposit probably formed at about 80+/-5.6 Ma(?), based on the dating of sericite alteration.

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.
