Description

The Eocene time period in the Great Basin marks a dramatic shift from compressional to extensional tectonics, coupled with the onset of voluminous subduction-related magmatism. These geologic changes are intimately and complexly linked with the regions world-class metal endowment. In this session, we review the key geologic aspects of the Great Basin in the Eocene and highlight recent work helping us understand the important relationship between tectonics, magmatism, and metallogeny.
