Abstract

Thermal modelling suggests that the problems posed by the high liquid temperatures (1,650C) of peridotitic lavas in Archaean greenstone belts, and the implied high degree of mantle melting (70%), are significantly reduced by considering uprise of a more refractory mantle diapir having an inherent density contrast with the surrounding mantle, and in a tectonic environment analogous to a marginal basin.
