Book Description
The Sphaler Creek and Flood Glacier map areas comprise the Galore Creek area, located within the Coast Mountains between the Stikine River and Mess Creek. The large tonnage Galore Creek alkaline porphyry copper-gold-silver deposit is located within the area mapped. Results of regional mapping and sampling in 1988 are summarized in the report. This report and accompanying maps incorporates new data and revisions to the 1:50 000 geology and mineral occurrence map. The project was conducted to produce detailed geological maps and a database better able to understand the Galore Creek area and aid in making new discoveries.

Book Description
Since 1859, the central Quesnel belt region of interior British Columbia has been the site of significant placer gold production. The identification of bedrock source areas for the placer gold and definition of the various mineral deposit types in this region are the main objectives of this field study. The study describes the regional geology, the geology of the central Quesnel belt (sedimentary units, volcanic successions, overlap units, continental clastic and volcanic deposits, intrusive suites), the region's geochronology and palaeontology, geochemistry, geologic structure, and metamorphism. It concludes with a section on economic geology of the region, discussing lode deposits, placer gold deposits, and regional geochemical studies.

Book Description
The Forrest Kerr-Mess Creek map area straddles the intermontane & coast belt boundary in north-west British Columbia. This report presents results of geological investigations undertaken to produce detailed maps & a database to better understand the geological setting of the area's mineral deposits and to aid in making new mineral discoveries. The introduction includes information on previous geological work in the area and on the regional geology. Chapter 2 describes the stratigraphy of the Paleozoic, Mesozoic, and later formations. Chapter 3 covers the area's intrusive rocks, including plutonic suites, dikes, and other intrusions. Chapter 4 discusses geologic structure, including deformational history and faults. The final chapter examines the area's economic geology and includes descriptions of mineral occurrences of four types: porphyry, skarn, sub-volcanic vein, and stratiform.

Book Description
The Stikine project area covers part of a mineral-rich belt near the Alaska panhandle/British Columbia border. The area includes important precious and base metal deposits such as Eskay Creek, and was selected for this study due to its high mineral potential and outdated geological database. This report, the result of four seasons of mapping in the area (1988-91), describes the area's regional tectonic setting and stratigraphy, intrusive rocks, structural geology and metamorphism, and economic geology (types of mineral deposits, timing of regional metallogenic events, isotope geology, exploration activity, mineral potential).

Book Description
Alaskan-type ultramafic-mafic complexes in British Columbia are potential hosts for commercially exploitable deposits of platinum group elements (PGEs). Such complexes are named for a distinctive suite of intrusions distributed along a narrow, northerly trending belt 600 kilometres long in south-eastern Alaska. All Alaskan-type complexes in British Columbia lie within the allochthonous terranes of the Intermontane Belt that were amalgamated and accreted to the cratonic margin of ancestral North America in the Mesozoic. This report examines the geology and PGE/noble metal geochemistry of eight specific complexes, providing information on regional geology and geochronology, structure, metamorphism, petrography, geochemistry, and mineralization. It then discusses PGE mineralization, using the Tulameen Complex and associated placers as a case study, and examines the economic potential of the complexes and their magmatic and tectonic settings.
