Wrangellia Flood Basalts in Alaska, Yukon, and British Columbia: Exploring the Growth and Magmatic History of a Late Triassic Oceanic Plateau
WRANGELLIA FLOOD BASALTS IN ALASKA, YUKON, AND BRITISH COLUMBIA: EXPLORING THE GROWTH AND MAGMATIC HISTORY OF A LATE TRIASSIC OCEANIC PLATEAU By ANDREW R. GREENE A THESIS SUBMITTED iN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in THE FACULTY OF GRADUATE STUDIES (Geological Sciences) UNIVERSITY OF BRITISH COLUMBIA (Vancouver) August 2008 ©Andrew R. Greene, 2008 ABSTRACT The Wrangellia flood basalts are parts of an oceanic plateau that formed in the eastern Panthalassic Ocean (ca. 230-225 Ma). The volcanic stratigraphy presently extends >2300 km in British Columbia, Yukon, and Alaska. The field relationships, age, and geochemistry have been examined to provide constraints on the construction of oceanic plateaus, duration of volcanism, source of magmas, and the conditions of melting and magmatic evolution for the volcanic stratigraphy. Wrangellia basalts on Vancouver Island (Karmutsen Formation) form an emergent sequence consisting of basal sills, submarine flows (>3 km), pillow breccia and hyaloclastite (<1 1cm), and subaerial flows (>1.5 km). Karmutsen stratigraphy overlies Devonian to Permian volcanic arc (—‘380-355 Ma) and sedimentary sequences and is overlain by Late Triassic limestone. The Karmutsen basalts are predominantly homogeneous tholeiitic basalt (6-8 wt% MgO); however, the submarine part of the stratigraphy, on northern Vancouver Island, contains picritic pillow basalts (9-20 wt% MgO). Both lava groups have overlapping initial and ENd, indicating a common, ocean island basalt (OIB)-type Pacific mantle source similar to the source of basalts from the Ontong Java and Caribbean Plateaus. The major-element chemistry of picrites indicates extensive melting (23 -27%) of anomalously hot mantle (‘—1500°C), which is consistent with an origin from a mantle plume head. -
Wrangell-St. Elias National Park and Preserve, Denali
Central Alaska Network Geologic Resources Evaluation Scoping Meeting Summary A geologic resources evaluation (GRE) scoping meeting was held from February 24 through 26, 2004 at the NPS regional office in Anchorage, Alaska to discuss geologic mapping in and around the parks and geologic resources management issues and concerns. The scoping meeting covered the three parks in the Central Alaska Network (CAKN) – Wrangell-St. Elias National Park and Preserve (WRST), Denali National Park and Preserve (DENA), and Yukon Charley Rivers National Preserve (YUCH). A summary of the status of geologic mapping and resource management issues is presented separately for each of these parks. The scoping summary is supplemented with additional geologic information from park planning documents, websites and NPS Geologic Resources Division documents. Purpose of the Geologic Resources Evaluation Program Geologic resources serve as the foundation of the park ecosystems and yield important information needed for park decision making. The National Park Service Natural Resource Challenge, an action plan to advance the management and protection of park resources, has focused efforts to inventory the natural resources of parks. The geologic component is carried out by the Geologic Resource Evaluation (GRE) Program administered by the NPS Geologic Resource Division. The goal of the GRE Program is to provide each of the identified 274 “Natural Area” parks with a digital geologic map, a geologic evaluation report, and a geologic bibliography. Each product is a tool to support the stewardship of park resources and each is designed to be user friendly to non-geoscientists. The GRE teams hold scoping meetings at parks to review available data on the geology of a particular park and to discuss the geologic issues in the park. -

Sanford Expedition After a comfy night preparing for your trip in Chistochina, jump into a ski-plane for a 20-minute flight as you and your gear are swept from the familiar rolling tundra and wildflowers of the Northern Wrangells into a world of ice and snow. Embrace the beauty, as well as the challenges, of winter camping, skirting crevasses, and unparalleled scenery as you climb or ski your way up the Sheep Glacier towards the summit of the 6th tallest peak in the United States. While presented with the classic mountaineering challenges like arctic weather, altitude, and glacier travel, Mt. Sanford also provides plenty of suitable terrain for learning and practicing the many mountaineering skills required to be safe in the mountains. Trip Highlights: • Stay in comfortable lodging in Chistochina before and after your trip • Gain over 13,000 vertical feet as you climb to the summit • Ample opportunities to learn and practice crevasse rescue, route- finding, whiteout navigation, and many other skills! • Perfect first Alaskan expedition for the budding high-altitude mountaineer • A great expedition for both climbers and skiers Mt. Sanford Expedition – Detailed Itinerary The following is a sample itinerary for this trip. Due to individual abilities and goals, as well as the demanding environment of Alaska, all of our trips are customized as they unfold. The guide will constantly make decisions based on weather, logistics and group dynamics to maximize each day’s experience. -

Other Bering Sea, Chukchi Sea, Gulf of Alaska, and the Pacific objectives are to describe geological hazards (i.e., Ocean. volcanic and seismic hazards) and geological resources (i.e., mineral and fossil fuel resources), and to describe the scientific, economic, and social significance of the earth for this region. As an example, the figure on the last page illustrates earthquakes belts for this dangerous part of the globe. What is the Northern Cordillera? The Northern Cordillera is comprised of Alaska and Western Canada. Alaska contains a series of parallel mountain ranges, and intervening topographic basins and plateaus. From north to south, the major mountain ranges are the Brooks Range, Kuskokwim Mountains, Aleutian Range, Alaska Range, Wrangell Mountains, and the Chugach Mountains. -
