Jagowerite

Jagowerite

Named for John Arthur Gower, a fomer Professor of Mineralogy at the University of British Columbia in Vancouver, Canada. Jagowerite is a rare mineral that can be found in only in the Hess River area in the Mayo Mining District of Yukon Territory, Canada. There, it is found in quartz veins that are filling tension fractures in carbon-rich argillite. Associated minerals include pyrite and hinsdalite. Jagowerite will fluoresce a greenish-white under long-wave ultraviolet light.
