由于缺乏建造岩系间判别线的数据，使用某些岩石学图解分析火山岩是不必要的困难。提供了足够点的坐标，以便能够在七个图内准确绘制边界线，即：(1)TAS-总碱（Na 2 O+ K 2 O）vs. SiO 2;（2）K 2 O vs. SiO 2;（3）AFM;（4）詹森;（5）KTP-K2 O-TiO 2-P 2 O 5;（6）FMS-（FeO-MgO）vs. SiO 2;（7）TAKTIP-K2 O（Na 2 O+ K 2 O）vs. TiO 2-P 2 O 5。这些边界的不同版本进行了整理，以表明其可变的位置，它表明，实验室间的分析精度足以占几乎所有的TAS和K2 O与SiO2图上的传播。
Use of some petrologic diagrams applied to analyses of volcanic rocks is unnecessarily difficult due to lack of data for construction of discriminant lines between rock series. Coordinates are provided for sufficient points to enable accurate plotting of the boundary lines within seven diagrams, viz.:(1) TAS-total alkalies (Na 2 O+ K 2 O) vs. SiO 2;(2) K 2 O vs. SiO 2;(3) AFM;(4) Jensen;(5) KTP-K 2 O TiO 2 P 2 O 5;(6) FMS-(FeO∗ MgO) vs. SiO 2; and (7) TAKTIP-K 2 O (Na 2 O+ K 2 O) vs. TiO 2 P 2 O 5. Different versions of these boundaries are collated to indicate their variable position, and it is demonstrated that inter-laboratory analytical precision suffices to account for almost all of their spread on the TAS and K 2 O vs. SiO 2 diagrams.
