The Archean Eon records the formation of Earth’s earliest continental crust, the establishment of fundamental geodynamic processes, and the emergence of life. Yet the timing and nature of Archean tectonics and the conditions of crustal metamorphism, remain poorly constrained. Although the ancient rock record is fragmentary, Archean cratons preserve evidence from mineral to regional scales, offering a rare window into these processes. We seek studies that provide new constraints on Archean crustal growth and stabilization, metamorphic processes, and the evolution of the lithosphere.
We invite contributions investigating the metamorphic and tectonic evolution of Archean terranes through petrology, in situ petrochronology, thermodynamic modelling, geochronology, geochemistry, geophysics and geodynamic modelling. We particularly welcome studies integrating multiple approaches at different scales. Together, these perspectives can help unravel the processes that shaped the early Earth.
