Mineralogical and geochemical fingerprints of alteration associated with the Cripple Creek alkaline-magmatic Au-Te deposit, Colorado
The Cripple Creek alkaline-magmatic Au-Te deposit, located in southern Colorado, USA, represents a world-class gold deposit. The deposit formed within an alkaline volcanic complex dominated by a central diatreme that records a complex history of brecciation, alteration and mineralizing events. The origin of gold and tellurium in the diatreme remains enigmatic. Questions also remain about why near-mine satellite intrusions of similar magmatic affinities and inferred age are weakly mineralized or barren. The broad aim of this study was to investigate controls on mineralization by characterizing ...
