A presentation of the GeoPRISMS Distinguished Lectureship Program, funded by the National Science Foundation

Join Harm Van Avendonk, a seismologist at the University of Texas at
Austin, to explore a major milestone in the history of geosciences – the
discovery of the Earth’s continental drift. Scientists learned that supercontinents of the past formed by the
collision and suturing of tectonic plates. These supercontinents later
broke into fragments along rift zones that lie very close to the ancient
suture zones. Known as the “Wilson Cycle,” this phenomenon reconfigured
our continents over many 100s of millions of years. Discover how this cyclical nature has allowed geologists to compare
offshore geological observations with rock outcrops in mountain belts,
where ancient continental margins can still be seen. Eat, drink, and learn with friends in a fun, relaxed setting! Food and drinks will be available for purchase.
