本文对中国东部一些新生代玄武岩中二辉橄榄岩团块的结构进行了研究。划分出了粗粒、残碎斑状和粒状变晶等三种主要结构类型,并对不同结构类型团块的组构进行了测定和研究,确定出粗粒—残斑—粒状变晶之过渡系列。认为上地幔普遍存在有塑性流动,初步探讨中国东部新生代时期的不同应力状态。 In this paper, the structures of lherzolites from some Cenozoic basalts in eastern China are studied. The three main types of structure, coarse grain, residual spot and granular deformation, were classified and the structures of different structure types were measured and studied to determine the transition series of coarse grain - . It is considered that the upper mantle generally has plastic flow and initially explores the different stress states during the Cenozoic era in eastern China.
