We report here for the first time the occurrence of Mg-Al granulites within the khondalite belt of the North China Craton and provide robust evidence for extreme crustal metamorphism at ultrahigh-ternperature (UHT) conditions in this region. The UHT indicator assemblages in these rocks include equil...
