Abstract

Abstract A coesite inclusion in garnet from an amphibolitized eclogite is described from the Dabie Shan region in central China. The eclogite with coesite occurs as a nodule (boudin?) in a several metres thick marble band in a regional eclogite fades terrain dominated by leucocratic garnet-bearing gneisses and eclogite bands. Probable quartz pseudomorphs after coesite have also been discovered as inclusions in garnet and omphacite from other localities in the Dabie Shan region, suggesting that a crustal slice of over 1000 km2 in area has been subducted to depths of over 90 km
