Holocene Tephras in Lake Cores from Northern British Columbia, Canada
935 Holocene tephras in lake cores from northern British Columbia, Canada Thomas R. Lakeman, John J. Clague, Brian Menounos, Gerald D. Osborn, Britta J.L. Jensen, and Duane G. Froese Abstract: Sediment cores recovered from alpine and subalpine lakes up to 250 km apart in northern British Columbia con- tain five previously unrecognized tephras. Two black phonolitic tephras, each 5–10 mm thick, occur within 2–4 cm of each other in basal sediments from seven lakes in the Finlay River – Dease Lake area. The upper and lower Finlay tephras are slightly older than 10 220 – 10 560 cal year B.P. and likely originate from two closely spaced eruptions of one or two large volcanoes in the northern Cordilleran volcanic province. The Finlay tephras occur at the transition between deglacial sediments and organic-rich postglacial mud in the lake cores and, therefore, closely delimit the termination of the Fraser Glaciation in northern British Columbia. Sediments in Bob Quinn Lake, which lies on the east edge of the northern Coast Mountains, contain two black tephras that differ in age and composition from the Finlay tephras. The lower Bob Quinn tephra is 3–4 mm thick, basaltic in composition, and is derived from an eruption in the Iskut River volcanic field about 9400 cal years ago. The upper Bob Quinn tephra is 12 mm thick, trachytic in composition, and probably 7000–8000 cal years old. A fifth tephra occurs as a cryptotephra near the top of two cores from the Finlay River area and is correlated to the east lobe of the White River tephra (ca. -

As agreed with your office, we gathered information on areas managed by two agencies: the Department of the Interior’s Bureau of Land Management (BLN) and the Department of Agriculture’s Forest Service. Specifically, this report provides information on (1) legislative guidance and the agency policies governing wilderness study area management, (2) the various activities and uses occurring in the agencies’ study areas, (3) the ways these activities and uses affect the areas, and (4) agency actions to monitor and restrict these uses and to repair damage resulting from them. Appendixes I and II provide data on the number, acreage, and locations of wilderness study areas managed by BLM and the Forest Service, as well as data on the types of uses occurring in the areas. -

Controls on Ore Deposition, Polaris Mining District, Pioneer Mountains
Controls on ore deposition, Polaris mining district, Pioneer Mountains, Beaverhead County, Montana by Thomas Edward Davis A thesis submitted in partial fulfullment of the requirements for the degree of MASTER OF SCIENCE in Earth Sciences Montana State University © Copyright by Thomas Edward Davis (1980) Abstract: The Polaris silver mining district is located along the southern margin of the Cretaceous Pioneer batholith. The silver ore replaces Mississippian age Madison Group limestone though in other districts of the Pioneer region Cambrian carbonates may also be mineralized. Other stratigraphic units present in the Pioneer district are the Precambrian Missoula Group and the Cambrian Meagher, Park, and Pilgrim Formations. These strata underwent six stages of faulting, probably during the Laramide orogeny. In chronological order, the fault systems strike: N 33° W; N-S; E-W; N 60° E; N 40° E; and N-S. A N-S fold set formed after the first stage of faulting, and an E-W fold set developed after all faulting. A third folding episode, evident only underground, has folded the Polaris (N 60° E) fault. The batholith intruded passively after the fifth and perhaps after the sixth episode of faulting. Ore mineralization is presumed to have followed intrusion of the batholith, at least of its deeper levels, by analogy with other ore districts in the Pioneer region. Ore replaces Madison Group limestone along N 60° E faults; only these faults were open at the time of mineralization since they were parallel to the direction of maximum stress. In the Polaris Mine, the principal mine of the district, the paragenetic sequence of mineralization is: pyrite, sphalerite; galena; pyrargyrite(?); and native silver. -

Northern Cordilleran Volcanic Province
Northern Cordilleran Volcanic Province The Northern Cordilleran Volcanic Province, formerly known as the Stikine Volcanic Belt, is a geologic province defined by the occurrence of Miocene to Holocene volcanoes in the Pacific Northwest of North America. This belt of volcanoes extends roughly north- northwest from northwestern British Columbia and the Alaska Panhandle through Yukon to the Southeast Fairbanks Census Area of far eastern Alaska, in a corridor hundreds of kilometres wide. It is the most recently defined volcanic province in the Western Cordillera. It has formed due to extensional cracking of the North American continent—similar to other on-land extensional volcanic zones, including the Basin and Range Province and the East African Rift. Although taking its name from the Western Cordillera, this term is a geologic grouping rather than a geographic one. The southmost part of the NCVP has more, and larger, volcanoes than does the rest of the NCVP; further north it is less clearly delineated, describing a large arch that sways westward through central Yukon.At least four large volcanoes are grouped with the Northern Cordilleran Volcanic Province, including Hoodoo Mountain in the Boundary Ranges, the Mount Edziza volcanic complex on the Tahltan Highland, and Level Mountain and Heart Peaks on the Nahlin Plateau. These four volcanoes have volumes of more than 15km3, the largest and oldest which is Level Mountain with an area of 1800km2 and a volume of more than 860km3. Apart from the large volcanoes, several smaller volcanoes exist throughout the Northern Cordilleran Volcanic Province, including cinder cones which are widespread throughout the volcanic zone. -

GEOLOGIC MAP of the PLAINS 30'X 60' QUADRANGLE
GEOLOGIC MAP OF THE PLAINS 30’x 60’ QUADRANGLE, WESTERN MONTANA Jeffrey D. Lonn, Larry N. Smith, and Robin B. McCulloch Montana Bureau of Mines and Geology Open-File Report 554 2007 This report has had preliminary reviews for conformity with Montana Bureau of Mines and Geology’s technical and editorial standards. Partial support has been provided by the STATEMAP component of the National Cooperative Geologic mapping Program of the U.S. Geological Survey under contract number 06HQAG0029. INTRODUCTION Montana Bureau of Mines and Geology (MBMG) staff selected the Plains 30’x 60’ quadrangle in western Montana for 1:100,000-scale mapping in order to fill the gap between the already completed Wallace (Lonn and McFaddan, 1999) and Missoula West (Lewis, 1998a) 30’x 60’ quadrangles (fig. 1). Bedrock of the map area is comprised mostly of low-grade metasedimentary rocks of the middle Proterozoic Belt Supergroup. The extraordinary thickness (>13 kilometers) of the Belt Supergroup and its complex deformation in western Montana have contributed to substantial stratigraphic and structural complexity in this region, and a geologically sound regional interpretation for this part of western Montana has been a goal of MBMG’s mapping program for the past decade. Harrison and others (1986) provided the foundation for mapping in this area with the publication of the Wallace 1O x 2O quadrangle, a 1:250,000-scale compilation that includes the Plains 30’ x 60’ quadrangle. The southwestern third of the Plains quadrangle contains structures of the Lewis and Clark Line, a poorly understood zone of west- northwest-trending faults and folds that transects the more northerly structural grain of western Montana (fig.
