WILLIAMS, Jr., and JANE G. FERRIGNO U.S. GEOLOGICAL SURVEY PROFESSIONAL PAPER 1386–J–1 The Rocky Mountains of Canada include four distinct ranges from the U.S. border to northern British Columbia: Border, Continental, Hart, and Muskwa Ranges. They cover about 170,000 km2, are about 150 km wide, and have an estimated glacierized area of 38,613 km2. Mount Robson, at 3,954 m, is the highest peak. Glaciers range in size from ice fields, with major outlet glaciers, to glacierets. Small mountain-type glaciers in cirques, niches, and ice aprons are scattered throughout the ranges.

  • Stratigraphy and Structure of Part of the Southern Madison Range, Madison and Gallatin Counties, Montana
    AN ABSTRACT OF THE THESIS OF Robert Rowland Rose' for the M.S. in Geology (Name) (Degree) (Major) Date thesis is presented Title STRATIGRAPHY AND STRUCTURE OF PART OF THE SOUTHERN MADISON RANGE, MADISON AND GALLATIN COUNTIES. MONTANA Abstract approved (Major professor The thesis area consists of 42 square miles located in Madison and Gallatin counties, Montana, in the south- ern part of the Madison Range. The strata exposed in the area range in age from Precambrian to Quaternary and have an aggregate thickness of more than 7,600 feet. The Paleozoic rocks, about 3,900 feet thick, are mainly carbonates but include sandstones, shales, and cherts of marine origin. Ordovician and Silurian forma- tions are absent. The Mesozoic rocks consist mainly of sandstones, shales, calcareous claystones, and argillaceous limestones of marine and continental origin. All Mesozoic periods are represented in this 3700 foot thick sequence of sedimentary rocks. The Cenozoic rocks and sediments include welded tuff, glacial deposits, and alluvium. Quaternary landslides cover about one -quarter of the thesis area. The structures are Late Cretaceous to Early Tertiary (Laramide) and Late Cenozoic in age. The Laramide struc- tures are northwest- trending, asymmetrical (steeper to the northeast) folds and high angle reverse faults. The Late Cenozoic structures are normal faults that displace Upper Cretaceous strata.

  • Diverse Base and Precious Metal Mineralization of the Mesoproterozoic Purcell Supergroup and Recurrent Magmatism in Southwestern Alberta Alexei S
    Diverse Base and Precious Metal Mineralization of the Mesoproterozoic Purcell Supergroup and Recurrent Magmatism in Southwestern Alberta Alexei S. Rukhlov Alberta Geological Survey, Energy Resources Conservation Board, 4999 – 98 Avenue, Edmonton, Alberta T6B 2X3, Canada [email protected] Summary This paper focuses on the distinct types of metallic mineralization within the Mesoproterozoic Purcell Supergroup in the Clark Range of southwestern Alberta. The numerous sedimentary- and igneous rock-hosted Cu-Ag, Pb-Zn-Cu and Au-Ag occurrences mark two major metallogenic events in southwestern Alberta: 1) Mesoproterozoic intracontinental rifting, mafic magmatism and hydrothermal convection, probably caused by the mantle plume, and 2) Cretaceous-Tertiary Laramide tectonics and igneous activity. The preliminary results of the field studies and new geochemical analyses by the Alberta Geological Survey will be discussed. Introduction Several world-class base and precious metal deposits exist in the Mesoproterozoic (1.50 – 1.32 Ga) Belt-Purcell basin of western North America (e.g., Sullivan and St. Eugene Pb-Zn-Ag-Au past-producers in British Columbia; Coeur d’Alene Ag-Pb and Blackbird Cu-Co mining districts in Idaho; Butte Cu-Ag-Au-Mo, Sheep Creek Cu-Co and Montanore Cu-Ag deposits in Montana) (Lydon, 2007). Since the first description by G.M. Dawson in 1886, numerous sediment- and igneous rock-hosted Cu-Ag, Pb-Zn-Cu and Au-Ag showings have been explored and partially developed within the Purcell Supergroup in the Figure 1.
