(a) alkali-silica diagram for determining subalkaline and alkaline fields [29], (b) AFM diagram for determining submagma type (tholeiitic or calc-alkaline), (c) and (d) position of the Chah Anjir samples on Y versus Nb and Rb versus Y + Nb diagrams [30]. Abbreviations: AFM = alkaline components (Na₂O + K₂O)-FeO_total-MgO, ORG = ocean ridge granites, Syn-COLG = syn-collision granites, VAG + Syn-COLG = volcanic arc granites + syn-collision granites, and VAG = volcanic arc granites. The analyzed samples were presents as black circles.
