Kenai Group
Kenai Group is a name given by Dall and Harris (1892) to sedimentary rocks in the Cook Inlet Basin, Alaska. These rocks are instead called the Kenai Formation by several other authors. See also *Kenai Peninsula The Kenai Peninsula ( Dena'ina: ''Yaghenen'') is a large peninsula jutting from the coast of Southcentral Alaska. The name Kenai (, ) is derived from the word "Kenaitze" or "Kenaitze Indian Tribe", the name of the Native Athabascan Alaskan tribe ... References Geology of Alaska Cenozoic Alaska {{geology-stub ...

The Cook Inlet Basin
The Cook Inlet Basin is a northeast-trending collisional forearc basin that stretches from the Gulf of Alaska into South central Alaska, just east of the Matanuska Valley. It is located in the arc-trench gap between the Alaska-Aleutian Range batholith and contains roughly 80,000 cubic miles of sedimentary rocks. These sediments are mainly derived from Triassic, Jurassic and Cretaceous sediments. The region is heavily influenced by two major tectonic elements which are still active in the area today. The western side of the basin lies directly above the Aleutian subduction zone where the Pacific Plate is subducting beneath the North American Plate. However the eastern side of the basin overlays the subduction of the Yakutat microplate beneath the North American plate. Active subduction along various sides of the basin produce regional compression that lead to major folding, faulting and the formation of anticline structures within the sediments. Anticline structures provide ideal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kenai Peninsula
The Kenai Peninsula ( Dena'ina: ''Yaghenen'') is a large peninsula jutting from the coast of Southcentral Alaska. The name Kenai (, ) is derived from the word "Kenaitze" or "Kenaitze Indian Tribe", the name of the Native Athabascan Alaskan tribe, the Kahtnuht’ana Dena’ina ("People along the Kahtnu (Kenai River)"), who historically inhabited the area. They called the Kenai Peninsula ''Yaghanen'' ("the good land"). Geography The peninsula extends about southwest from the Chugach Mountains, south of Anchorage. It is separated from the mainland on the west by Cook Inlet and on the east by Prince William Sound. Most of the peninsula is part of the Kenai Peninsula Borough. Athabaskan and Alutiiq Native groups lived on the peninsula for thousands of years prior to Gerasim Izmailov becoming the first European to explore and map the area in 1789. The glacier-covered Kenai Mountains, rising , run along the southeast spine of the peninsula along the coast of the Gulf of Alaska. Much ...

Geology Of Alaska
The geology of Alaska includes Precambrian igneous and metamorphic rocks formed in offshore terranes and added to the western margin of North America from the Paleozoic through modern times. The region was submerged for much of the Paleozoic and Mesozoic and formed extensive oil and gas reserves due to tectonic activity in the Arctic Ocean. Alaska was largely ice free during the Pleistocene, allowing humans to migrate into the Americas. Geologic History, Stratigraphy & Tectonics Compared with other areas of the North American continent, Alaska formed in the recent geologic past. Until 200 million years ago, western North America terminated at the Rocky Mountains, 120 miles further inland than the current shoreline, until the addition of the Yukon-Tanana Terrane. The Birch Creek Schist is the oldest rock in Alaska's interior and forms the core of the Yukon-Tanana Terrane with muscovite-quartz schist, mica quartzite and graphite schist. This intensely folded and rock unit extends f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
