The discovery of low-temperature and high-pressure eclogites across Niutuling area in the ultrahigh pressure eclogite Unit and its significance
|
Abstract:
On the basis of the field investigation,petrology and thermodynamic estimates for eclogites in the middle of the South Dabie Terrane (SDT),the eclogites across Niutuling area in the the middle of SDT belong to low-temperature and high-pressure eclogites,and no underwent ultrahigh pressure metamorphism.The country rocks for the ecolgites are schists,gueisses and plagioclase amphibolite.Garnet display enhedral or subhedral crystal with inclusions in earlier stage,the peak metamorphic temperature and pressure ...
