The comparison of petrology, lithofacies, petro-geochemistry and tectonic environment of the rapakivi granite both from Qinling-Kunlun and world shows that the rapakivi granite has same or consistent characteristics: rapakivi structure, sub-aluminous, high-potassic, alkali-rich magma, two-peak magma assemblage and formed in post-collision environment. However, there are some certain differences in some geochemical index, forming age of magma, and geotectonic position of outcropping.

The volcanic rocks of the Xiong'er Group is also widespread in the Baoji and Lvliang area and also appear as 1.75Ga-old mafic dyke swarms, A-type granites, later anorthosite and rapakivi granites (1.75-1.70Ga), and alkaline granitoids (~1.65Ga). These intrusive rocks are assumed to have genetic link to the volcanic rocks of the Xiong'er Group.
