The Penrose Conference convened on 14-18 June 2006 at Lander, Wyoming to discuss the possible time that plate tectonics started on Earth. Although participants agreed that plate tectonics involves horizontal plate motions on Earth's surface, there was a debate about how best to track plate tectonics back in time. Regardless of the fact that no consensus was reached, most of the evidence at hand suggested that "modern-style" plate tectonics "evolved" from an earlier form of proto-plate tectonics sometime in the Archean. Participants agreed though that answering the question of when plate tectonics began is critical for understanding the evolution of the solid earth system.
