Early Jurassic Rossland Group, Southern British Columbia by Trygve Höy,Kathryn P. E. Dunne,British Columbia. Geological Survey Branch,British Columbia. Ministry of Employment and Investment Pdf

The Rossland Group in south-eastern British Columbia comprises intermediate to mafic volcanic rocks and associated clastic rocks of Lower Jurassic age. The Group hosts a variety of gold and silver deposits and continues to be a target of mineral exploration. The purpose of the study reported is to develop a better understanding of the nature, timing, and controls of mineralization in the Group, particularly the intrusion-related gold-copper veins in the Rossland camp. The report describes the Rossland Group stratigraphy, its paleotectonic setting, and associated intrusions. It summarizes the structure of the Rossland Group area and presents a tectonic model for the Group. Information is also included on the regional geologic setting and the geochemistry of the Elise Formation and plutonic rocks.

Metallogeny and Mineral Deposits of the Nelson-Rossland Map Area by Trygve Höy,Janet Elizabeth Gabites,Kathryn P. E. Dunne,British Columbia. Geological Survey Branch,British Columbia. Ministry of Energy and Mines Pdf

The Jurassic Rossland Group in south-east British Columbia is a volcanic arc succession that contains a variety of deposits typical of volcanic arcs. This report focusses on deposits in the Group, particularly on those that have had recent exploration, and on the metallogeny of the Nelson-Rossland map area. The report first reviews the regional geology of the area and describes a number of type examples of mineral deposits in Rossland Group rocks & others in the area. These include carbonate-hosted deposits, volcanogenic massive sulphides, porphyry copper-gold deposits, skarns, and gold-quartz & polymetallic veins. The principal focus is on the deposits of the Rossland copper/gold mining camp, the second largest lode gold producing camp in the province. The regional geology around Rossland is summarized, the main deposit types are described, and a model for intrusive-related gold-sulphide veins is presented. Appendices include a table of mineral occurrences in the area, production data for the area's metallic deposits, a petrographic report, analyses of samples, reports on geochronological dating & isotope characterization, and fluid inclusion data.

Mesozoic Assembly of the North American Cordillera by Robert S. Hildebrand Pdf

"In this well-illustrated book, Hildebrand expands upon his model for the development of the North American Cordillera detailed in Special paper 457. Starting with an overview of Cordilleran geology he goes on to provide an in depth look at how the Rubian ribbon continent was assembled. He integrates the complex geology of the Cordillera into an actualistic model involving arc magmatism, arc-continent collision, slab failure magmatism, and transcurrent motion in both Rubia and the western North American margin. While much of the focus is on the assembly of the Rubian ribbon continent, Hildebrand explores its interactions with North America during the Sevier and Laramide events and concludes that North America was the lower plate in both"--Provided by publisher.

Jurassic Stratigraphy of the Queen Charlotte Islands, British Columbia by B. E. B. Cameron,H. W. Tipper Pdf

"During the course of the present detailed stratigraphic studies careful attention was paid to occurrences of bitumen, dead oil, fetid lithologies, and possible porous intervals within the Jurassic rocks. Hydrocarbons, derived from normal petroleum type hydrocarbons, were noted throughout the lower and middle Jurassic. The present evidence suggests that hydrocarbon reserves may be encountered in the subsurface in northern Graham Island, southern Hecate Strait, and Queen Charlotte Sound. These potential resources involve mesozoic oil within the Jurassic or Cretaceous rocks, or escape oil of Mesozoic age in Tertiary sandstone units." --

Skarns in British Columbia by Gerald E. Ray,I. C. L. Webster,British Columbia. Ministry of Employment and Investment,British Columbia. Geological Survey Branch Pdf

Skarns in British Columbia have historically been important sources of iron, tungsten, copper, and gold. This publication begins with an introduction on skarn terminology and the problems of skarn identification. It then reviews a genetic model of skarn formation and presents descriptive profiles of eight types of skarn deposits; describes the database of at least 735 skarn occurrences in the province, and the number and distribution of skarns in British Columbia according to their associations, class, age, and distribution; and notes the ages of British Columbia skarns and the total production of various metals extracted from British Columbia skarns. Subsequent sections provide information on assays and metal ratios of mineralized skarns, skarn mineralogy, skarn mineral chemistry, chemistry of skarn-related intrusions, and the mapping and evaluation of skarns. The appendix contains a listing of 735 skarn occurrences in British Columbia, giving deposit name, MINFILE number, latitude/longitude, elements and minerals present, and associated rocks and their ages.

Lower and Middle Jurassic Radiolarian Biostratigraphy and Systematic Paleontology, Queen Charlotte Islands, British Columbia by E. S. Carter,B. E. B. Cameron,P. L. Smith Pdf

Extensive geological investigation of Mesozoic strata of the Pacific Rim is currently underway to determine the hydrocarbon potential of these rocks. Precise biostratigraphic control is essential for advances and substantial new information on the Jurassic biostratigraphy and taxonomy of Jurassic radiolarians from the Queen Charlotte Islands is presented in this report. Five new genera and 42 new species are described, most of which have restricted, and therefore useful, biostratigraphic ranges. A preliminary radiolarian zonation is proposed, calibrated with associated ammonite and foraminiferal faunas.

Geology of the Pacific Northwest by William N. Orr,Elizabeth L. Orr Pdf

The geologic history of the Pacific Northwest is as unique as the region itself. Created via tectonic plate movements and accretionary events, the original terranes were subsequently covered by sedimentary layers, ash, lavas, and glacial debris. These processes, begun millions of years ago, continue to affect the area, as seen in the eruption of Mount St. Helens and catastrophic Japanese tsunamis created by earthquakes in the Pacific Northwest. Understanding of the regions geology has led to new insight in volcanic eruption prediction, disaster preparedness, the environmental effects of mining, and urban development as it relates to geologic hazards. The Orrs detailed and informative writing style appeals to those with geologic training as well as beginners with an interest in the region. Each chapter covers a specific subregion, allowing for maximum flexibility both in the classroom and for the casual reader. The authors central theme that continental plate tectonics are the fundamental processes of Northwest geologic history permeates throughout the book.
