Discriminant analysis identified geochemical differences in A-type granitoids, suggesting a novel typification approach for Phanerozoic and Precambrian samples.
Based on the results of discriminant analysis of samples of Phanerozoic intraplate and post-collisional A-type granitoids with similar geochemical characteristics, a diagram is proposed that allows typing at least part of the A-granitoid samples. The applicability of the proposed diagram for the typification of not only Phanerozoic, but also Precambrian A-type granitoids is shown.
