摘要
本文用数学方法讨论了地幔平衡部分熔融与岩浆分离结晶关系式随D_A变化的相对大小,进而对这两种成因作出判别。最后对最优判别元素的选择作了讨论。
This paper uses mathematical methods to deal with the relative magnitude of both equations of partial fusion of equlibrium in the mantle and magmatic fractional crystallization as partition coefficient D_A varies,and distinguishes the two genetical models quantitatively. At last, we will discuss selections of the most distinctive elements.
