大同两类玄武岩在空间上分野明显，可能与桑干河断裂对软流圈地幔上涌的控制以及区域上岩石圈-软流圈作用程度的变化有关。 | | 3. | The early tertiary alkali basalts from yangyuan which contain abundant mantle xenoliths exhibit very homogeneous sr - nd isotopes with snd = 5 . 5 . their pb isotopes are similar to those of the depleted mantle ( dm ) and their trace element characteristics resemble those of oceanic island basalts ( oib )
含幔源包体的阳原早第三纪碱性玄武岩具有均一的sr - nd同位素组成( nd 5 . 5 ) ，其pb同位素组成与亏损地幔( dm )相似。 | | 4. | The compositions of usual elements and rare earth elements and inclusions of corundum megacrysts related to alkali basalt in changle , shandong province , are analyzed . in the main parts of corundum megacrysts are a large number of fluid - melting inclusions , zircon , ta - columbite inclusions , and in the central crystal core are a large number of melting inclusions . the corundum megacrysts were formed in different periods and different physical chemistry conditions . the crystal core was formed in magma system , and the main parts were formed in inhomogeneously geochemical conditions in which magam and fluid phases coexisted
分析山东昌乐与碱性玄武岩有关的刚玉巨晶不同部位的常量元素、稀土元素及包裹体组成.刚玉巨晶的主体以大量流体?熔体包裹体、锆石、铌(钽)铁矿包裹体为主，而巨晶中的“晶核”部位则以大量的熔体包裹体为主，反映研究区的刚玉巨晶是在不同的阶段形成的.刚玉“晶核”以及“铜皮刚玉”形成于熔体相为主的体系中，而主体刚玉则形成于熔体?流体过渡的急剧变化的不均一的地球化学环境中 | | 5. | Given their oib - type trace element pattern and depleted sr - nd isotop ic composition , the datong alkali basalts are interpreted to be generated within the asthenospheric mantle but at a shallow depth compared to the yangyuan alkali basalts . the datong tholeiitic basalts exhibit low snd values ( 1 - 4 ) . their sr - pb and nd - pb isotopic correlations are consistent with a mixing between the depleted mantle and emi - like component
大同地区第四纪时期同时产出碱性和拉斑玄武岩，碱性玄武岩也主要来自于软流圈地幔，岩浆起源深度小于阳原样品；拉斑玄武岩具有较低的nd ( nd = 1 - 4 ) ， pb - nd以及pb - sr同位素相关关系暗示其可能是dm和型富集地幔( emi )组分之间混合的结果，反映了软流圈和岩石圈地幔之间的相互作用，岩浆起源较浅。 |
