结果显示,中国大陆地幔热流的空间分布不均匀。
Our result shows the nonuniform distribution of mantle heat flow in China.
它是大陆地幔低度部分熔融产生的碱性玄武岩浆,通过深部AFC混合,尤其是浅部结晶分异机制形成的。
They are formed from alkali basaltic magma that slightly melted out of continental mantle by AFC mixing in depth, especially by the fractional crystallization in shallow horizon.
