Abstract
In addition to the Triassic Hong'an low-T-high-P eclogite and the Xinxian coesite-bearing kyanite-glaucophane eclogite, Silurian coesite-free amphibole eclogites occur in the Sujiahe region, NW Dabie Shan of central China. A comprehensive study of petrology, Nd-Sr, O-H isotopes and fluid inclusions has been carried out for the Sujiahe eclogites. Geothermobarometry of mineral assemblages gave peak P-T conditions of 600-730 °C and 14-19 kbar, and retrograde metamorphism of 530-685 °C and 6 kbar. The eclogites have high
