Geoscience Seminar April 24: Francis MacDonald
The geoscience department weekly seminar presents:
Speaker: Francis MacDonald
Topic: Arc Collisions in the Tropics set the Earth's Climate State
Francis Macdonald's research focuses on the interactions of tectonics, climate, and biological evolution through Earth history. This work begins with geological mapping, and uses stratigraphic analysis, isotope geochemistry, geochronology, paleomagnetism, and paleontology to reconstruct paleoenvironments and tectonic histories. Recent projects have focused on the initiation and duration of Snowball Earth events, the chemical evolution of the ocean leading up to the Cambrian explosion, and the Neoproterozoic to Paleozoic tectonic evolution of North America and Asia.
