Mid-Term Test II - sample test questions

Make a simplified drawing of the relative position of the main Cordilleran terranes in the region between northern British Columbia and southern California, and annotate each terrane with: A) the name of the terrane, e.g. Franciscan, B) its plate tectonic character, e.g. rift zone, oceanic arc, and C) the relative age of accretion of the terrane to the Cordilleran margin,
e.g. Paleozoic, Triassic, Jurassic, Cretaceous.

Compare the southern component of the Canadian Cordillera with the northern component.

Explain the basis of current controversies concerning the evolution of the Canadian Cordillera.

Describe the terrane arrangement in the Klamath Mountain section of the Cordilleran system;
what does it suggest about the mechanism of growth of the western margin of North America?

How did the Klamath-California section of the Cordillera evolve during the Mesozoic.

Describe the geology of the Cordillera

Using the following template list the terranes associated with the following orogenic systems:

What terrane contains eclogites and blueschists in California?

What tectonic environment does the Great Valley Sequence represent?

What is significant about the Western Paleozoic and Triassic unit of the Klamath Mountains,
and what terrane is its equivalent in the Canadian Cordillera?

 Give the TerraneName,   Rock types,   General Age Range,  Paleogeographic Environment
 for the terranes making up the Newfoundland Appalachian system

Make a sketch of the relative Early Paleozoic paleogeographic  distribution of the four continents and continental terranes that will eventually accrete to form the Appalachian-Caledonian system. Annotate the names of the terranes and continents, and give the names of the oceans that separated them.
 
What is the name of the oceanic suture in the Appalachian system?

 What is the name of the Carboniferous/Permian orogeny in the Appalachian system?

Name the three orogenies thought to mark the collision of the continental terranes.

What kind of evidence has been used to determine the relative latitude occupied by the terranes at the time of their formation?

Name three terranes within the Newfoundland segment of the Appalachians.

Compare the geology of the opposing continental margins of the Appalachian system.

Etc, etc.
