| 摘 要： | 中国东部新生代宏玄武岩广泛发育，它们在时间和空间上表现为明显的分带。在新生代玄武岩中赋存着丰富的地幔碎裂－二辉橄榄岩包体和高压巨晶，为研究上地幔组成和岩浆演化提供大量信息。人选必其他研究者的资料，从岩石学，矿物学，地球化学及热力学的观点，对中国东部新生代玄武岩中赋存的深源包体和新生代辉石地温进行探讨。

THE MANTLE DERIVED NODULES AND CENOZOIC PYROXENE GEOTHERM OF EASTERN CHINA |
| |
| Abstract: | The Cenozoic basalts are widely distributed in Eastern China.They are displayed in obvious zones in the time and the space.The Cenozoic basalts in this region contain abundant upper mantle nodules,including lherzolite and high pressure megacrysts,which give much information about composition of upper mantle and magmatic evolution.This paper is based on the data of the author and other investigators.It deals with the mantle derived nodules in the Cenozoic basalts and the Cenozoic pyroxene geotherm in Eastern China in the light of petrology,mineralogy,geochemistry and thermodynamics. |

| Keywords: | upper mantle nodules infusible restites subduction zone pyroxene geotherm consumption degree Mohorovicic discontinuity |
