Description / Table of Contents: Abstract The characteristic structures of granite-greenstone and high-grade gneiss terrains are reviewed, using the Superior Province and the North Atlantic craton as examples, with the object of finding a suitable tectonic model to explain both. The granite-greenstone terrain exhibits a combination of gravity-driven vertical tectonics and regional horizontal compression, while the high-grade gneiss terrain shows dominantly subhorizontal high-strain foliation affected by later refoldings. A uniformitarian plate tectonic model may not be appropriate to the Archaean in the likely absence of eclogite-driven subduction and because of practical problems in explaining the deformation patterns. Various alternative mechanisms are considered to explain the structure of the high-grade gneiss terrains in particular. It is concluded that the most fruitful model is tectonic underplating, whereby the crust is thickened from beneath by the emplacement of crustal slices detached from their mantle lithosphere — itself underplated independantly. Such a process could have operated in the North Atlantic craton coevally with greenstone formation and subsequent diapirism in the Superior Province. Sub-horizontal N-S compression affected both cratons in the late Archaean, after the above processes had taken place, when the crust had become sufficiently rigid to be able to transmit regional stresses.
