Book Description
This report documents the geological setting of the mining camp and geologic features of the major mineral deposit types. New ideas about the tectonic setting and metallogenic history of the district are also presented. The area lies near the eastern margin of the Coast Mountains at the head of the Portland Canal, a fiord 115 kilometres long, which marks the southeastern boundary between the Alaska Panhandle and northwestern British Columbia.

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
Following their recognition by GUmbel (1874), lamprophyres were treated for an entire century as little more than obscure curiosities. Although this situation has changed recently, with a flowering of publications and active workers, lamprophyres remain almost the only group of igneous rocks which have not yet received attention in a dedicated monograph. In five exploratory reviews (1977-1987), the writer aimed to set out what was known about these rocks. The lUGS Subcommission on igneous rock systematics had meanwhile presented its nomenclatural framework (Streckeisen 1979). All this has now been overtaken by a recent explosion of interest, epitomized not least by lamprophyres' greater prominence in the 4th International Kimberlite Conference Proceedings. More data have become available since 1985 than over the entire previous century, and it is obviously impossible for such an extraordinary outpouring to be fully reviewed in this first, preliminary book. At the risk of dissatisfying some readers, therefore, this book concentrates on factual matters, and on a broad overview rather than minutiae. Because not even a world map of known lamprophyres was previously available, almost half the book is deliberately taken up by the first global lamprophyre compilation, and its commensurately extensive Bibliography. Such a compendium of largely objective information is believed to be of more immediate interest and lasting value than a premature pottage of petrogenetic polemic. Chapters 1-7 bring previous studies up to date, and concentrate on factual information.

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.
