Abstract
The Ba-feldspar celsian [BaAl2Si2O8] has been found in quartz-skarn-sulfide deposits at the American Beauty and Summit View Mines in the Ruby Mountains, Nevada. The celsian is present in quartz-skarn-polymetallic sulfide ores formed during Jurassic and Tertiary phases of skarn formation. Well-shaped microcrystals of celsian, along with sulfide minerals and apatite, fill cavities in quartz and are related to a retrogressive hydrothermal mineral paragenesis that took place during a final stage of contact-metamorphic mineralization at temperatures of approximately 300°C. Prismatic crystals of celsian were subsequently fragmented and rounded during superposed ductile deformation of the enclosing quartz and became part of a Tertiary mylonitic fabric at the American Beauty Mine.
