Sulfosalt melts: evidence of high-termperature vapor transport of metals in the formation of high-sulfidation lode gold deposits

Mavrogenes, John; Henley, Richard; Reyes, Anges; Berger, Byron

Description

In enargite-gold (high-sulfidation) vein deposits, magmatic fluid is considered responsible for the transport of metals and sulfur into the depositional regime. New data from Field-Emission SEM analyses of sulfosalt mineral assemblages (primarily enargite and tennantite) from El Indio, Chile, and Summitville, Colorado, provide direct evidence of high-temperature deposition, including the following: (1) the preservation of delicate euhedral quartz assemblages in sulfosalts, (2) a range of...[Show more]
