Chasing an Ancient Volcanic Firestorm in the Northern Cordillera of Montana
volcanism, Montana, Eocene, magmatism
The Eocene Epoch was characterized by an outburst of volcanism in the northern Cordillera, stretching from the northwestern United States to central British Columbia. Volcanism was contemporaneous with a tectonic shift to extensional conditions that together dramatically reshaped the landscape, formed valuable ore deposits, and drove a warming climate. Eocene volcanic centers preserved throughout the northern Cordillera hold an exquisite record of magmatism, but many remain understudied despite their importance to understanding fundamental tectonomagmatic processes and potential long-term impacts on civilization. This talk explores several of Montana’s Eocene volcanic centers, presenting new data and insights into this fascinating and somewhat enigmatic part of Earth’s history.
