Description

Gold is unique because it is the only economically important metal or major by-product from at least 11 different deposit types. The metal itself accounts for roughly half of the world's nonferrous exploration activity, equating to corporate expenditure on the order of US$5 billion annually. It also holds a unique and fascinating position as a commodity that demands a great deal of collaborative research and exploration attention.

For these reasons, the previous SEG Publications Board chairs, Stuart Simmons and Rich Goldfarb, promoted the idea of a volume focused on basic geologic descriptions of the world's major gold deposits and provinces as a major contribution to the Society's 100th-anniversary celebrations.

Sponsored by Barrick, the volume is introduced with a series of thumbnail sketches that give a general flavor of the principal currently recognized gold deposit types. The 29 deposit descriptions and 7 province overviews provide in-depth descriptions of the exploration history and regional and local geologic settings that led to the lithologic, structural, alteration, and mineralization features of the deposits themselves.

This accompanying webinar will further highlight these remarkable deposit types over the course of a one-hour mini-lecture series, focusing on the following deposit types:

  • Introduction (Sillitoe)
  • Epithermal and porphyry deposits (Simmons)
  • Carlin (Robert)
  • Archean orogenic and other deposits (Robert)
  • Younger orogenic and other deposits (Goldfarb)
  • Epilogue – gold in solutions (Simmons)

Following these lectures, a Q&A session moderated by Halley Keevil will address important questions regarding the nature of these deposits, and a forum for discussion will be opened up to the attendees.
