Sediment-Hosted Gold: Carlin & Orogenic Styles

This course involves discussion of recent advances in understanding genesis of, and exploration for, sediment hosted gold-arsenic deposits. Emphasis will be placed on Carlin deposits, Nevada; Sukhoi Log and related deposits, Russia; deposits in the Victorian Goldfields; emphasis on geology and geochemistry of deposits with focus on gold and sulfide paragenesis and LA-ICPMS analysis and mapping of gold & sulfides. Suites of hand specimens of ores and host rocks will be available for discussion.

Leaders:

Ross Large (CODES), Rob Scott (CODES) , Poul Emsbo (USGS)
