HERCYNITE-QUARTZ GRANULITES - PHASE-RELATIONS, AND IMPLICATIONS FOR CRUSTAL PROCESSES
The assemblage Zn-poor hercynite + quartz, occurring with cordierite, garnet and/or sillimanite, is diagnostic of high-temperature granulite-facies metamorphism at mid-crustal depths. It has been recorded from a handful of terrains worldwide, in which peak temperatures probably exceeded 800°C, and p...
