    FEATURES OF ULTRAHIGH AND HIGH PRESSURE FELSIC ROCKS IN THE JIAONAN UPLIFT,SHANDONG, AND THEIR P T EVOLUTION

      Graphical Abstract
      • Abstract
    • The eclogite bearing high pressure metamorphic belt in the Jiaonan uplift is the eastward extension of the Dabie ultra high pressure belt.The principal mineral associations of ultra high metamorphism are Grt+Ky+Rut+Jd+Q and Sp+Zo+Ab±Grt±Omp,and the P T conditions of metamorphism are T =600～700 ℃ and P =2.3～2.6 GPa.The ultra high pressure rocks and high pressure rocks both underwent two phases of retrogressive metamorphism and have similar clockwise P T paths.
