It has been shown in the Al(Na+K+Ca/2) diagram that the Jinla granitoids are all plotted within the area of "S" type of granites, but the samples from Laochang amphibole admellite, Menglinshan biotite admellite and Nanla K-feldspar graniteporphyry are scattered gradually far away from the boundary between "I" and "S" types of granites, implying that the components from the upper mantle gradually decreasing from the Laochang amphibole admellite to the Menglinshan biotite admellite and then to the Nanla K-feldspar granite porphyry.

3上述三类花岗岩样品皆位于S型花岗岩区，但从老厂似斑状角闪二长花岗岩，勐林山似斑状黑云二长花岗岩，到南腊碱长花岗斑岩，样品分布逐渐远离"I"型花岗岩和"S"型花岗岩的分界线，这表明自老厂似斑状角闪二长花岗岩至勐林山似斑状黑云二长花岗岩，到南腊碱长花岗斑岩幔源组分逐渐减少。
