According to the sr-nd isotopic characteristics of peridotite xenoliths and their host basalts, it indicates that xenoliths in hannuoba, puning area may represent source area of the host basalt because of the xenoliths and host rocks being in the same plot; however, the xenoliths is not directly related to their host rocks of the others area for the xenoliths plot out of the range of their host basaltic rocks . thermal dynamics calculation shows that the peridotite xenoliths are formed in the condition of pressure of 9.45-25kb and temperature of 945-1281 橄榄岩包体及其寄主玄武岩的sr-nd同位素研究表明，汉诺坝与普宁地区部分包体样品投点落在其寄主玄武岩nd和sr同位素的分布范围内，表明橄榄岩包体代表了寄主玄武岩的源区，而其它大部分地区的包体其寄主玄武岩范围之外，表明寄主玄武岩和橄榄岩包体无成因联系，橄榄岩包体只是偶然包体。

There are distributed a great number of cenozoic basalts and mantle derived xenoliths in north china and south china . for understanding the materials constitutes, evolution, mantle metasomatism, and inhomogeneity of the lower crust and upper mantle, there is a must of doing some research on these host basalts and the xenoliths 华北、华南地区发育大量新生代玄武岩及幔源包体，对其进行研究，有利于进一步深入了解下地壳和上地幔的物质组成、演化、地幔交代和不均一性以及地球物理反演结果的可靠性等。

Major, trace element composition and sr-nd-pb isotopes of the cenozoic basalts from yangyuan ( hebei province ) and datong ( shanxi province ), which are located to west of the daxinanling-taihanshan gravity lineament, as well as mineral chemistry, major and trace element composition and sr-nd isotopes of mantle xenoliths from yangyuan are reported in this thesis 本文报道了大兴安岭-太行山重力梯度带以西河北阳原和山西大同新生代玄武岩的元素和sr-nd-pb同位素地球化学及阳原幔源包体的矿物化学、元素和sr-nd同位素地球化学，据此对华北克拉通西部上地幔的性质和过程进行了初步讨论。
Based on the study of correlativity of ol-opx-cpx contents in north china and south china, it shows that some peridotite xenoliths from hannuoba, pingquan, nvshan, puning, qiongbei, and niutoushan area may represent the older mantle material compositions, and some peridotite xenolith from ximeng, penglai, linqu, quzhou, mingxi, and liuhe area may represent the younger mantle material compositions 通过对华北、华南两区橄榄岩包体中的o1与opx及cpx的相关关系的分析研究认为，华北汉诺坝和平泉地区，以及华南女山、普宁、琼北、牛头山等地区的部分橄榄岩包体，代表了老地幔；锡盟、蓬莱、临朐及衢州、明溪、六合等地区的部分橄榄岩包体代表了较新地幔。
