Abstract

The KFMASH grid provides a good description of reaction textures observed in many high temperature granulites. However, as the system has been investigated for rocks with excess melt, this grid can be applied only in its presence. Archaean Al-Mg granulites studied do not display textural evidence for melting. Instead, paragenetic analysis shows that melt-absent reactions are stable in the KFMASH system. A new grid based on Hensen and Harley's and the present paragenetic analysis has been worked out. It accounts for all the observed reactions and indicates a previously established decompression for Mole In Ouzzal. There is an abridged English version. -English summary
