Hancockite is the lead bearing analog of epidote, which Armbruster et al. (2006) sought to rename as epidote-(Pb). Ultimately, the International Mineralogical Association reverted the name to hancockite (Revheim & King, 2016). The mineral name honors Elwood P. Hancock (1836-1916), of Burlington, New Jersey, prolific collector of Franklin minerals.
Hancockite is rock-forming here as brick-red masses. Associated are micaceous hendricksite, black franklinite and granular yellow andradite; minor fluorescent willemite and calcite are also present. Representative hand sample. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
