Lunch Break Science: Titanium Isotopes and Plate Tectonics

Wednesday, February 24 at 12:00pm to 12:45pm

Plate tectonics is one of the most important processes in shaping the Earth. Over eons It helped form continents, mountains, volcanoes, basins for oceans and much more. These formations were crucial in helping to develop our atmosphere and sustain life.


While scientists agree plate tectonics were fundamental in Earth’s formation, it has been highly debated for decades about how and when it began. Join geologist Dr. Sarah Aarons as she shares exciting new clues into when the process may have begun and how analyzing titanium isotopes in ancient rocks provides compelling new evidence.


  • What: “Titanium Isotopes in the Acasta Gneiss and the Origins of Plate Tectonics,” presented by Dr. Sarah Aarons, Assistant Professor, Scripps Institution of Oceanography, UC San Diego
  • When: Wednesday, February 24, 12 - 12:45 pm
  • Where: Zoom meeting in the comfort of your home
