The Qinglongshan O- and H-isotope anomaly occurs within a coesite-bearing, eclogite-facies regional metamorphic belt in Eastern China near Donghai in Jiangsu province. The anomaly is defined by low values of δ 1 8 O and 5D. Garnets from eclogite have δ 1 8 O as low as -11‰ and rutiles are -15‰ (VSMOW). Phengites have δD of -120‰ (VSMOW). The anomaly is Neoproterozoic in age. Surface outcrops of coesite-eclogite-facies rocks with unusually low δ 1 8 O and 8D values extend over an area of at… CONTINUE READING
