经研究，华北克拉通古地幔以含石榴石的二辉橄榄岩、方辉橄榄岩及纯橄榄岩为主．地幔交代作用强烈，岩石富集不相容元素，明显高于南非及西澳克拉通者．扬子克拉通古地幔主元素亏损程度差，交代作用较弱，岩石为石榴石／尖晶石二辉橄榄岩．秦岭造山带壳、幔交界带的岩石类型复杂，包括蛇纹石化尖晶石二辉橄榄岩（蛇纹岩）、石榴石辉石岩、榴闪岩、变辉长岩及变玄武岩等．蛇纹岩遭受强的塑性流变，剪切变形结构发育．与克拉通相比，地幔交代作用很弱．３个地幔域的古地温状态有差异，秦岭造山带最高，扬子克拉通居中，华北克拉通最低．上述结果表明，两克拉通的古地幔特征相差显著，暗示经历了不同的演化过程．交代作用可能发生在１７００Ｍａ以前和１１００～５００Ｍａ，后者强于前者．造山带地幔的剪切变形明显强于克拉通地幔
After the study, the North China Craton ancient mantle to garnet-containing lherzolite, harzburgite and dunite mainly. Mantle accounts for strong role in rock incompatible enrichment elements, significantly higher than those in South Africa and Western Australia carats. The main elements of the Yangtze craton ancient mantle have a poor degree of depletion and accountability is weak, and the rocks are garnet / spinel lherzolites. The rock types of the Qinling orogenic belt and the mantle boundary zone are complex, including serpentinized spinel lherzolite (serpentinite), garnet pyroxene, garnet rock, gabbro and metamorphic basalts. Serpentinite suffered strong plastic deformation, shear deformation structure development. Compared with the craton, the mantle metasomatism is weak. The paleo-geothermal states of the three mantle fields are different, with the highest in the Qinling orogenic belt, with the Yangtze craton being the lowest and the lowest in the North China craton. The above results show that the characteristics of the two craton ancient mantle difference significantly, suggesting that underwent a different evolutionary process. Interchange role may occur before 1700Ma and 1100 ~ 500Ma, which is stronger than the former. The shear deformation of the orogenic belt mantle is significantly stronger than that of the craton
