摘　　要：Objective High-T eclogites from the North Dabie complex zone （NDZ）, central China underwent a complex metamorphic evolution involved in ultrahigh-pressure （UHP） and high- pressure eclogite-facies metamorphism, and subsequent granulite-facies overprinting and amphibolite-facies retrogression during the Mesozoic continental deep subduction and exhumation. As a consequence, the eclogites were strongly affected by multiple decompression and re-crystallization processes during exhumation. Some eclogites have even been wholly transformed to garnet granulite, or garnet amphibolite, or even garnet-absent amphibolite.Objective High-T eclogites from the North Dabie complex zone （NDZ）, central China underwent a complex metamorphic evolution involved in ultrahigh-pressure （UHP） and high- pressure eclogite-facies metamorphism, and subsequent granulite-facies overprinting and amphibolite-facies retrogression during the Mesozoic continental deep subduction and exhumation.
