Numerous clear to opaque-white calomel crystals on micro-crystalline quartz over red cinnabar. The calomel fluoresces bright orange under shortwave UV light. Minor orange-yellow terlinguacreekite visible. From Dunning et al., 2019, page 43: "Calomel is uncommon in the mercury ores. It was found associated with cinnabar, eglestonite and liquid mercury at the McDermitt mine (Rytuba and Glanzman 1979; McCormack 1986), and with photosensitive cinnabar, terlinguaite and an Hg-S-Cl mineral, probably corderoite, at the Opalite mine (McCormack 2000). Recent discoveries of calomel crystals in silica-rich light gray rock associated with kleinite and terlinguacreekite presents an interesting association. Colorless calomel tetragonal crystals up to 0.5 mm cover older quartz in pockets."
