Virtual Seminar for Precambrian Geology

Starting early in 2021

Covid-19 has presented unprecedented challenges to circulating scientific progress and keeping us connected. Our hope is that organizing this Virtual Seminar for Precambrian Geology (VS-PG) will help keep ideas moving within our scientific community during the prolonged pandemic quarantine.

This virtual seminar series is open to all who wish to participate and has the goal to join researchers interested in any aspect of Precambrian Geology. The following list includes key topics relevant to our understanding of the Precambrian Earth including, but not limited to:

  • The development and emergence of cratons & early plate tectonics
  • Precambrian Mineral deposits and LIPs
  • The redox evolution of the atmosphere and ocean
  • The evolution of life
  • Climate evolution in the Precambrian: Greenhouse and icehouse states
  • The evolution of key biogeochemical cycles throughout the Precambrian
