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.
