Location: Bozeman, Montana, USA


Includes the following sessions:

T3. Precambrian I: Archean and Paleoproterozoic crustal evolution of Western Laurentia

Convenors: David Mogk (, Paul Mueller (

This session will cover all aspects of the earliest creation and growth of the North American continent, including contributions from tectonics, geochemistry, and geochronology; studies of surficial deposits and environments; and the record of earliest life on Earth.

T4. Precambrian II: Meso- and Neoproterozoic evolution of Western Laurentia: in honor of Don Winston

Convenors: Paul Link (, Reed Lewis (

This session will cover the continued growth and evolution of the North American continent through the Proterozoic and into the Cambrian, including tectonic reconstructions; petrologic and geochemical additions and modifications; metallogenesis; and evidence of early life, with special attention to the formation and development of the Belt Basin and the succeeding rifted margin. This session is associated with Field Trip 8 (Mesoproterozoic tectonics and sedimentation along the southern margin of the Belt Basin: in honor of Dan Winston).

T6. Yellowstone-Snake River Plain-Columbia River Volcanic Province: geology, petrology, geophysics, and geodynamics

Convenors: Bill Phillips (, Dan Moore (

New petrologic, seismic, and geodetic results have reinvigorated debate on the origin of Miocene-Recent volcanism within the Yellowstone-Snake River Plain-Columbia River Volcanic Province. This theme session seeks contributions in the fields of geology (including geologic mapping), petrology, geophysics, and geodynamics. Contributions from throughout the province are encouraged.

T10. The Early Triassic magmatic firestorm of the US and Canadian Cordillera: geochemical, petrological, and tectonic constraints

Convenors: Richard Gaschnig (, Genet Duke

The Eocene and Paleocene Epochs were characterized by a widespread flare-up of volcanism and plutonism in the Cordillera, stretching east from central Oregon to South Dakota, north into British Columbia, and south into Colorado and New Mexico. We seek contributions dealing both with the petrology and geochemistry of individual magmatic centers and the larger space-time-composition patterns and links between magmatism and tectonism of this unusual time in the history of the Cordillera.
