  • 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.

  • Geographic Characteristic of the Republic of Armenia
    GEOGRAPHIC CHARACTERISTIC OF THE REPUBLIC OF ARMENIA TERRITORY Republic of Armenia is situated in south-western part of Asia. The country occupies the north-eastern part of Armenian plateau – between Caucasus and Nearest Asia (the inter- river territory between the middle flows of Kur and Araks rivers). The total territory is located in the latitude of 380 501 - 410 181 N and longitude of 430 271 - 460 371 E. In the north and east it borders with Georgia and Azerbaijan, and in the west and south – Turkey and Iran. The country’s area comprises 29743 km2, of which 46.8% - agricultural land, 34.9% - mountains, plateaus and other land, 12.7% - forests and 5.6% - water surface. The highest elevation of the country is the Peak of Aragats Mountain (4090 m), the deepest landslide – the Debed river canyon (390 m). The longest extension from north-west to south-east is 360 km, and from west to east – 200 km. The largest lake in the territory of Armenia is Sevan Lake (surface 1239 km2), the longest river is Araks – 158 km (the total length – 1072 km). 6 Marzes of the Republic of Armenia in Figures, 1998-2002 The top of Aragats mountain MOUNTAIN TOPS Name Place The height above sea level, m Aragats Aragats massif 4090 Kaputjugh Zangezur mountain range 3906 Ajdahak Geghama mountain range 3598 Spitakasar Geghama mountain range 3555 Vardenis Vardenis mountain range 3522 Aramasar Bargushat mountain range 3392 Ishkhanasar Gharabagh plateau 3549 Baghatssar Meghri mountain range 3250 Khustup Khustup-Katar mountain range 3214 Legli Javakhk mountain range 3157 Gogi Vayk mountain range 3113 Tej ler Pambak mountain range 3101 Mets Eghnakhagh Eghnakhagh mountain range 3042 Bovakar Halab mountain range 3016 Urasar Bazum mountain range 2993 Miapor Miapor mountain range 2993 Qashatagh Sevan mountain range 2901 Aray ler Aray massif 2577 Armenia is a mountainous country.

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.

At that time the division New Brunswick and Ben Edwards from Dickinson Col- discussed creating an award for the best thesis in volcanol- lege.

    RECOGNIZING ICE-CONTACT TRACHYTE-PHONOLITE LAVAS AT THE MOUNT EDZIZA VOLCANIC COMPLEX, BRITISH COLUMBIA, CANADA by Kristen A. LaMoreaux B.S., Kent State University, 2002 Submitted to the Graduate Faculty of Arts and Sciences in partial fulfillment of the requirements for the degree of Master of Science University of Pittsburgh 2008 UNIVERSITY OF PITTSBURGH ARTS AND SCIENCES This thesis was presented by Kristen A. LaMoreaux It was defended on June 17, 2008 and approved by Dr. Michael Ramsey Dr. Thomas Anderson Thesis Director: Dr. Ian Skilling ii Copyright © by Kristen A. LaMoreaux 2008 iii RECOGNIZING ICE-CONTACT TRACHYTE-PHONOLITE LAVAS AT THE MOUNT EDZIZA VOLCANIC COMPLEX, BRITISH COLUMBIA, CANADA Kristen A. LaMoreaux, M.S. University of Pittsburgh, 2008 Mount Edziza Volcanic Complex (MEVC) lies within the Northern Cordilleran Volcanic Province (NCVP), in northwest British Columbia, Canada. The eruption products have been emplaced in a variety of subaerial, sub-ice and subaqueous environments from about 8Ma to less than 2000 y.b.p. (Souther, 1992). Ice Peak Formation (IPF) trachyte lava flows of approximately 1Ma age (Souther, 1992) are exposed at Ornostay Bluff (OB) and Koosick Bluff (KB). These flows comprise basal flow breccias overlain by massive conchoidally-fractured lava with large, poorly-developed columns, and local flow banding. Edziza Formation (EF) approximately 1Ma (Souther, 1992) phonolite is exposed at Triangle Dome (TD). TD can broadly be divided into an upper and lower zone. The upper zone comprises poorly-developed columns in addition to prominent jointing. In the lower zone the columns are planar and 75cm- 3m-wide in the interior of the complex grading into fan-like and curved subhorizontal columns <75cm-wide in the outer margins of the lower zone.
