THE ORIGIN OF KHONDALITES - GEOCHEMICAL EVIDENCE FROM THE ARCHEAN TO EARLY PROTEROZOIC GRANULITE BELT IN THE NORTH CHINA CRATON
The dominant rock types in the khondalite suite in the Archean to Early Proterozoic granulite belt of north-central China are sillimanite-garnet gneiss (SGG), quartz-garnet gneiss (QGG), and quartz-feldspar gneiss (QFG). Field and geochemical results from the China khondalites and khondalites from o...
