2.The results place constraints on the chemical geodynamics of the Yangtzeplate subduction beneath the Sino- Korean plate:(1)eclogite and mafic granulite from North Dabie also have low δ 18O values as the ultrahigh pressure eclogite and gneiss in South Dabie,therefore their protoliths.结果对扬子板块向华北板块的俯冲提供了如下化学地球动力学制约： (1)北大别榴辉岩和基性麻粒岩与南大别超高压榴辉岩和片麻岩一样，具有较低的δ 18O值，表明它们在板块俯冲前经历了高温地表水热液蚀变，在超高压变质阶段流体以亏损 13C为特征； (2)部分低δ 18O值榴辉岩的共存矿物对之间保存了氧同位素平衡分馏，记录了榴辉岩相变质温度，指示这些榴辉岩在地幔的居留时间较短，折返初期的冷却速率较大； (3)退变质作用过程中存在显著的差异性氢氧同位素交换，早期阶段流体具有内部缓冲性质，而晚期则具有外部来源； (4)东大别大理岩显著富集 13C，反映出其母岩灰岩的沉积环境为封闭的大陆边缘盆地，西大别苏家河大理岩的δ 13C值接近于正常海相碳酸盐，指示其母岩形成环境为宽广开阔的海洋。
