Classification of Igneous Rock Series | The Journal of ...

2020-8-30 · Some rock series cannot be properly classified either as alkalic or as sub-alkalic. To meet this situation a simple extension of the present twofold classification is proposed; this takes the form of a fourfold division into alkalic, alkali-calcic, calc-alkalic, and calcic groups. It is shown, from a partial graphical representation of thirteen rock series, that the silica value at which the ...
