This 3-day workshop will synthesize EarthScope results relevant to the tectonic evolution of North America, with a key objective to set the stage for a much larger collaboration to develop a Community Model for the 4-D Evolution of the North American Continent. The principal workshop goals are to 1. Synthesize EarthScope results from the primarily 3-D geophysical experiments that captured a snapshot of present day North America, especially those that have relevance to the temporal evolution of the continent, 2. Integrate EarthScope results with existing continent-scale geologic and tectonic knowledge, and 3. Produce a summary document that highlights successes from EarthScope research that has advanced our knowledge of the 4-D tectonic evolution of North America. We also intend for this workshop to lead to a GSA Special Paper or Geosphere themed issue with papers co-authored by workshop participants on topics relevant to the geological evolution of the continent.
In addition, we hope to expand on these syntheses to initiate a new community model for the lithospheric evolution of North America. The overarching scientific goal is to unravel how and why the continent evolved over ~4 billion years to the current state. That is, to address long-standing questions of how the time-integrated processes of plate tectonics and surface processes produce the earth structures we see today. This vision remains an idea that requires both community input and discussions of what is practical with technology available today.
