(a) The classification of plutonic rocks using the parameters - [26]. Parameters are defined by the = [4Si − 11(Na + K) − 2(Fe + Ti)] and = (Al + 2Mg + 6Ca) and (b) the chemical classification of plutonic rocks using total alkaline versus SiO₂ from [27] and modified by [28]. The analyzed samples were present as black circles.
