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:橄榄拉斑玄武岩浆、白榴碧玄岩浆、碧玄岩浆.根据玄武岩的地质、岩石学和地球化学特征,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.
The mineral-magma equilibrium conditions and magmatic viscosity, density, and velocity of magma, such as magma physical parameters, were quantitatively calculated. Three kinds of primary basaltic magmas: Bi mysterious magma. According to the comprehensive analysis of basalt geology, petrology and geochemistry, magmatism origin, deep geology and geophysics, it is considered that the basalt in this area is the product of the deep thermal disturbance in the continental lithosphere.
