摘　　要：High-pressure metamorphic eclogite, as a window of study for depth level of lowermost crust and mantle, has an important indicating significance to composition, property and accretion of continental lower crust. Archaean high-pressure metamorphic rocks of eclogite facies are very rare. According to this fact, it is suggested that there is a difference in principle between the mechanisms of formation and evolution of early Precambrian and Phanerozoic continental crust. Smelov and Beryozkin first reported that some
