Archean Tectonics Debate and Symposium - 27 & 28 November 2014
Since the late 1960’s when plate tectonics was first widely accepted, geologists have long considered how far back in Earth’s history plate tectonic processes operated. Until the late 1980’s, many geologists considered that plate tectonic activity has only operated in the past 1 Ga. Since then, however, new discoveries have pushed back the envelope such that some geologists believe tectonic activity has occurred since the early Archean. However, this is a matter of continued dispute and is currently unresolved. Understanding of dynamic Archean tectonics is critical for comprehending the evolution of Australian continent, and processes that led to the formation of world class gold and base metal provinces.
