Abstract

Essentially all models for the tectonic evolution of the high-grade Limpopo belt of southern Africa invoke a single orogenic event at 2.7 Ga involving the collision of the Zimbabwe and Kaapvaal cratons with a distinct central zone. By implication, rocks within the belt must have followed parallel pressure-temperature-time (P-T-t) paths. New geochronological data indicate, however, that magmatism occurred at distinct times in different parts of the belt over a span of at least 70 m.y. In addition, the data indicate that high-grade metamorphism and associated tectonism in the central and southern marginal zones occurred at about 2.0 and 3.15 Ga, respectively. -from Authors
