Abstract

The occurrence, mineralogy and geochemistry of eclogites in the Mt. Dabie area show that they were subjected to a high-pressure metamorphism together with the country rocks, but their petrochemistry and REE geochemistry show some difference from those of the country rocks. The geochemical characteristics of the eclogites are similar to those of both continental tholeiitic basalt and oceanic tholeiitic basalt. The rocks probably subducted to the upper mantle with the Dabie metamorphic complex. When elevated to the surface, they were subjected to different stages of retrogressive metamorphism.
