The related UHP metamorphic P-T-t path has been reconstructed which could be subdivided into four stages,including prograde(StageⅠ)and UHP metamorphism(StageⅡ)during deep-subduction,and initial quartz eclogite-facies(StageⅢ)and later amphibolite-facies(StageⅣ)retrograde metamorphism during exhumation.

Based on the detail studies of relationship between metamorphism and deformation of Mayuan Group (early Proterozoic) and Mamianshan Group (late Proterozoic)in Northern Fujian and P-T-t paths determinated from the zoned garnets, as well as the data of structural geology and isotopic geochronology, it is proved that the metamorphic rocks of Mayuan Group formed in early Proterozo.
本文通过对闽北麻源群和马面山群变质岩详细的变质变形关系的研究和石榴子石环带测定P-T-t轨迹的应用,结合构造地质和同位素年代学的资料,证实了麻源群变质岩形成于早元古代或更老年代,在早元古代末期遭受过中压、中高温变质,但在晚元古代晋宁期与中元古代形成的马面山群岩石一起经历了强烈的变质变形作用,表现为早元古代麻源群岩石遭受强烈改造,具有早期地壳再活化特点。

This paper applies the theory of P-T-t trace in these problems.
本文应用P-T-t轨迹理论重新认识这些问题,认为引起辽河群变质作用的根本原因是大陆碰撞造山带使辽河群俯冲到地下深处;辽河群变质作用在时间上和空间上有独特的演化特征;辽河群变质作用与不同规模的构造或不同层次的构造的关系是不一样的。
