| 摘 要： | 根据３０多个玄武岩体的详细的实际资料，将研究区内中新生代玄武岩划分为５种类型，分属２个岩浆系列，判别出３种原生岩浆。橄榄拉斑玄武岩、白榴碧玄岩和碧玄岩为原生岩浆；碱性橄榄玄武岩和石英拉斑玄武岩为进化岩浆。玄武岩的矿物学和地球化学特征表现出大陆板内玄武岩之属性，是大陆岩石圈小范围热扰动的产物

| Abstract: | According to the detailed practical data of over thirty basaltic bodies, the Mesozoic Cenozoic basalt is divided into five types and they belong to two magmatic series. Three kinds of primary magma which is olivine tholiitic basalt, leucobasanite and basanite are recognized. Alkali olivinebasalt and quartz tholiitic basalt are evolutional magma. The mineralogical and geochemical properties of the basalt show the natures of basalt of within continental plate. It is recognized that those basalts are the produce of deep thermal disturbance in continental lithosphere. |
