| 摘 要： | 本文提出了用线性约束条件下的非线性最优化方法,同时拟合部分溶融过程中的主要和微量元素;通过对新疆东天山某些花岗岩类成因的实际模拟计算,取得了良好效果;此方法解决了以往单纯考虑微量元素时难以解决的源岩矿物发生反应、残留相矿物含量难以确定等困难,赋予部分熔融程度更为实际的意义。

| Abstract: | This paper advanced a nonlinear programming method under linear constraints, fit-
ting simultaneously major and trace elements during partial melting processes. Through
actual applications to the simulation of geneses on granitoids in East Tianshan Mountains.
Xinjiang, China, the method demonstrates effects. Comparing to model method relying on
trace elements only, the method has solved the problem that the reactions among the min-
eral of source materical take place, gotten rid of the difficulty to ascertain contents of relict
solid phases after partial melting, and given real meaning for degree of partial melting. |
