The accreted terranes that form Alaska are only some of the vast number of terranes that have added to the mass of western North America over the past million years.

The array of terranes can be traced from National Park Service sites in Alaska southward through British Columbia, North Cascades and Olympic national parks in Washington State. The North Cascades are still rising, shifting and forming. Geologists believe that these mountains are a collage of terranes, distinct assemblages of rock separated by faults.

Fossil and rock magnetism studies indicate that the North Cascades terranes were formed thousands of miles south in the Pacific Accreted Terranes of the North Cascades Range Washington book.

To appreciate how these chapters of Washington’s history formed, we suggest you tackle them one at a time from oldest to youngest. Washington. NCNP was founded in ____ The North Cascades are the result of compression (a collision) Terranes extend along the western edge of North America from Mexico to Alaska.

True. Most of the Terranes of the North Cascades were accreted during the _____ and early Cenezoic. mesozoic. The terranes of the North Cascades were. One of the great things about the North Cascades is that it exposes basement rock of accreted terranes –fabulously.

In the high peaks, the so-called “Crystalline Core” of the North Cascades, you can see the Skagit Gneiss, some of which originated as granitic rock in a magmatic arc much like today’s Cascade Volcanoes, and some of which.

This introductory chapter focuses on the accreted terranes in Washington and on some of the distinctive rock types and mineral deposits that characterize them. These terranes are the pericratonic Quesnel terrane in the Okanogan Highlands (unit Q of Fig.

Methow valley is excavated in an exotic terrane of folded Mesozoic sedimentary and volcanic rocks faulted between crystalline blocks. Repeated floods of Columbia River Basalt ca. 16 Ma drowned a backarc basin to the southeast.

Unmetamorphosed sedimentary and volcanic accreted terrane rocks are widespread across the western part of the Cordillera with metamorphosed rocks present primarily in the northern California Coast Ranges, the northern Sierra Nevada, the Blue Mountain region of Oregon, the Klamath Mountains, and the North Cascades.

The Cascade Range is part of a vast mountain chain that spans for over miles, from Mount Shasta, in northern California to British Columbia in the north. The beautiful North Cascade Range, located in northwestern Washington State, has some of the most scenic, and geologically complex mountains in the United States.

Gordon1, Robert B. Miller2, Jeffrey D. Vervoort 3, and Christopher M. Fisher. Three major terranes comprise the Blue Mountains composite terrane in Idaho. These are Permian to Triassic fragments of oceanic island arcs, continental fringing arcs, and various subduction-related mélange that were amalgamated, and underwent Late Triassic metamorphism and Triassic-Jurassic sedimentation, before collision with the North American margin.

The North Cascade Range, although it has a few prominent volcanoes, is predominantly an uplifted block of accreted terranes. The collision that accreted these terranes created intense pressure, leading to metamorphic conditions that formed rocks such as slate, phyllite, schist, gneiss, and marble.

It was added (accreted) to the North American continent during the Mesozoic –probably some million years ago. Photo 6. Wallowa Mountains, Oregon. Just west of Hell’s Canyon are the Wallowa Mountains, Oregon’s premier alpine country outside of the Cascades.

Like Hell’s Canyon, the Wallowas contain the accreted Wallowa terrane. Something Borrowed: Accreted Terranes Basement in the Coast Range of western Washington consists of Eocene marine basaltic and mafic intrusive rocks formed in a near-margin rift setting that were accreted to the continent in the Eocene (Wells and others, ; Babcock and others, ).

Positive aeromagnetic anomalies in the Coast Range. A series of accreted terranes, starting with the Quesnellia terrane accreted in the Jurassic, and the latest Siletzia, which stretches from southern Oregon to southwestern British Columbia, and which accreted 50 million years ago, comprise the basement for the remaining part of the state.

In addition, the Coast Range of British Columbia, this book says, was made of accreted terranes just like the North Cascades.

In short, the picture given is that if you take away the High Cascade volcanoes, then you'd have two ranges: 1. the Cascades south of about I to northeast California, and 2.

Controversy surrounds the Late Cretaceous tectonic history of northwestern North America, with many studies suggesting significant terrane translation for parts of the Insular and Intermontane superterranes and the plutonic rocks of the Coast Plutonic Complex–North Cascades range that separate the two superterranes (e.g., Monger et al., ; Cowan et al., ) ().

Three crustal segments identified by Schmidt et al.

Tabor and Ralph A. Haugerud The Cascade Range of Washington State, a western rampart of the North American Cordillera, comprises an older basement of accreted terranes and a cover of sedimentary and volcanic rocks. The Snoqualmie Pass quadrangle (fig.

1, on map sheet) lies at the north edge of the volcanic cover, where the regional structural. mentary rocks accreted to North America by the Late Tri-assic (Irwin, ; Snoke and Barnes, ).

The forearc of central Oregon to southern Washington lies within the Columbia Embayment, a region defined by positive Bou-guer anomalies and whose boundary delineates the Early Eocene margin of North America (Couch and Riddihough, ).

On the West coast of North America, the coast ranges and the coastal plain form the margin. Most of the land is made of terranes that have been accreted onto the margin.

In the north, the insular belt is an accreted terrane, forming the margin. This belt extends from the Wrangellia Terrane in Alaska to the Chilliwack group of Canada.

The “suture” between the newly accreted Insular Belt and the old continental margin (the Methow Shelf) is a major northwest-trending fault through the North Cascades named the Ross Lake Fault.

Many geologists believe the Wallowa Mountains in northeastern .Cascade Range in southwestern Washington occupy a com- plex tectonic setting along the margin of two distinct crustal blocks. Crust in the eastern block beneath the southwest Washington Cascades is composed of Mesozoic and older accreted terranes, volcanic arcs, and underplated magmatic rocks.Columbia River Basalts: Features of a Typical Flow.
