1. Course Objectives 
This short course will put the various classes of deposits into their tectonic, stratigraphic and chronological settings.  We will use examples, but our focus will be toward the broader scene:  where do the deposits occur, what are their characteristics, when do they occur, where should you look for others, what should be here that we havenít found yet?  The models will be applicable on a world scale, and, of course, many are based on type deposits elsewhere in the world.

2. Overview of the Tectonic Evolution and Setting of Mineral Deposits in the Canadian Cordillera 
Several themes are explored in attempting to understand the distribution patterns of deposits in this geologically and structurally complex area.  First, metallogeny is a large scale feature that is intimately linked with tectonic setting and plate tectonism; second, metallogenic epochs are characteristically times of widespread igneous activity - plutonism or volcanism; and third, while plate tectonic activity localizes mineral districts it cannot be used to predict the location of individual deposits.

3. Sediment Hosted Exhalative Deposits of Ancestral North America and Related Terranes  
  
This segment examines a very important class of mineral deposits in the Canadian Cordillera - the sedimentary exhalative (SEDEX) massive sulphide deposits.  This class of stratiform, syngenetic deposit is found in intracratonic basins and miogeoclines of Middle Proterozoic through Middle Paleozoic age.

4. Carbonate-Hosted Massive Sulphide Deposits in  British Columbia 
This segment deals with non-skarn metallic and related deposits that are hosted within carbonate rocks.

1. Tectonic and Lithologic Controls of Volcanogenic Massive Sulphide Deposits 
Volcanogenic massive sulphide deposits (VMS) are an important source of copper, zinc, lead and precious metals in Canada and, historically, in British Columbia.  This segment describes VMS deposits, outlines their tectonic setting and presents genetic models.  Volcanogenic deposits in B.C. are classified and compared to well-known type examples described elsewhere.  Includes a guide for exploration of VMS deposits, including summarizing the tectonostratigraphic environments that favor their distribution, and presenting structural, lithological, geochemical and geophysical exploration guidelines.

2. Mineral Potential of Ultramafic Rocks in B.C. with Emphasis on Precious Metals 
The material presented in this section of the Short Course represents a synopsis of mineral deposits that are hosted by, or spatially-associated with, ultramafic-mafic complexes in the Cordillera.  For present purposes, we have focused on the base and precious metal commodities, notably chromite, nickel, platinum-group elements (PGE) and gold, with a bias towards the PGE.

1.  Gold in the Canadian Cordillera - A Focus on Epithermal and Deeper Deposits 
An overview of gold production, classification and deposit distribution.  Discussions of hydrothermal fluid sources and gold solubility; Cordilleran mesothermal and epithermal deposits.

2. An Overview of Skarn Deposits 
This segment presents an overview of skarn deposits.  The characteristics, alteration assemblages, tectonic setting and distribution of the various subclasses of skarn deposits are examined, particularly where they relate to examples in British Columbia.  Special emphasis is directed towards the characteristics, exploration criteria and potential of gold and precious metal enriched (PME) skarns in the province and elsewhere in the North American Cordillera.

1. Porphyry Deposits in the Canadian Cordillera 
In the present economic climate, combined base and precious metal deposits present the most attractive exploration targets, and significant gold and silver values characterize many porphyry copper deposits in the Canadian Cordillera.  In 1986, 60 percent of the gold produced in British Columbia - 12.5 tonnes of gold and 500 tonnes of silver - were by-products from base metal mines, and by 1988 more than half the provinceís gold reserves were in porphyry deposits.  Porphyry deposits carry 90 percent of the provinceís copper reserves.
