岩浆作用过程的一种有效判别方法──(1/C_i)-(1/C_j)和(或)lgC_i-lgC_j图解法

AN EFFECTIVE DISCRIMINANT APPROACH OF MAGMATIC PROCESSES:GRAPHIC INTERPRETATION OF 1/C_i-1/C_j AND (OR) lgC_i-lgC_j

本文利用一种新的方法和（或）lgCi－lgCi图解法，明显地区分出地幔平衡部分熔融作用和岩浆分离结晶作用。并以亚速尔群岛中Terceira岛火山岩和汉诺坝玄武岩的实际资料验证了所推导的方法。

In this paper a new approach-graphic interpretation of and (or) lgC-lgC will besubmitted to obviously discriminate two magmatic processes including mantle equilibrium partialmelting and magmatic fractional crystallization. The approach is tested in terms of practical datafrom Terceira Island (Azores) volcanic rocks and Hannuoba (Hebei) basalts.
