| 摘 要： | 定量计算了湘南中新生代多种类型玄武岩的矿物－熔浆平衡条件和岩浆粘度、密度、上升速度等岩浆物理参数，识别出了三类原生玄武岩浆，橄榄拉斑武岩浆、白榴碧玄岩浆、碧玄岩浆、根据玄武岩的地质岩石学的地球化学特征，及岩浆起源条件，深部地质和地球物理等方面资料的综合分析，认为本区玄武岩是大陆岩石圈深部热扰动的产物。

| Abstract: | In magmatic physical parameters e.g. equilibrium conditions between mineral and melt, viscosity, density and uplifiting velocity of magma are calculated quantitatively. Three kinds of primary magma are recognized, olivine-tholeiitic basalt, leucobasanite and basanite. According to the analysis about the properties of geology, petrology and geochemistry, generation condition of magma, deep geology and geophysics, those basalts are recognized as the products of deep thermal disturbance in continental lithosphere. |
