T11C:
Something Borrowed, Something New: Integrating EarthScope and Geologic Results to Better Constrain the 4-D Evolution of North America Posters

Submit an Abstract to this Session



Session ID#: 25299

Session Description:
The ~4 billion year evolution of the North American continent has resulted in a complex tapestry of tectonic and geologic terranes. In unraveling the tectonics and surface processes that produced the modern structure of North America, three-dimensional models of present-day lithospheric structure constructed using EarthScope data provide an ideal complement to recent geological and geochemical studies. This session will integrate EarthScope results at both regional and continental scales with geologic data and models that constrain the temporal evolution of the continent. We welcome abstracts that synthesize a variety of data types and methodologies in order to better understand the 4-D evolution of the North American lithosphere.
