CONTINENTAL THERMAL AND TECTONIC REGIMES DURING THE ARCHEAN

Abstract:

Describes how metamorphic pressures estimated from mineral assemblages in Archaean high-grade terrains may be used to constrain geothermal regimes in the Archaean continental crust. Discusses results, which imply that Archaean continental thermal regimes were similar to present-day ones. These observations, together with the common interpretation of komatite melting temperatures as being representative of Archaean upper mantle temperatures, are inconsistent with earth thermal histories based ...
