摘要
Objective High-pressure(HP)and ultrahigh-pressure(UHP)minerals tend to be preserved in mafic and ultramafic metamorphic rocks(e.g.eclogites and garnet amphibolite)rather than felsic rocks.Generally,HP and UHP rocks are thought to be formed as a result of the tectonic burial or subduction of oceanic crust or thicked continental lithosphere to depths corresponding to the eclogite facies metamorphism,followed by fast uplift(Ernst et al.,2007).
