摘要
通过对分离结晶作用和批式熔融作用C_l^y/C_l^x-C_l^y图解的数学分析,笔者认为,虽然C_l^(La)/C_l^(sm)-C_l^(La)图解在一定程度上能区分这两种不同岩浆作用过程,但是,Treuil等的解释是不完全的。直线的斜率和截距还极大地受参数C_o^x,C_o^y,D_x,D_y的影响。该图解并非总是有效。本文还给出了一般式C_l^y/C_l^x-C_l^y在其它方面的可能应用。
<ABSTRACT>
Based on the analysis and comparison of C_l^y/ C_l^x-C_l^y diagrams of fractional
differentiation and batch melting, the author suggests that although C_l^(La)/ C_l^(Sm)-C_l^(La) dia-
gram can to certain extent distinguish the different magmatic processes, but the explanation
given by Treuil et al. is not complete, the slopes and intercepts of lines are greatly influenced
by the parameters (C_0~x, C_0~y, Dx, Dy) which control the magmatic processes. This paper al-
so shows some geological applications of the C_l^y/ C_l^x-C_l^y diagram.
