Dated from Proterozoic to Mesozoic, they have poly-circle characteristics, found from one tectonic circle to another, which is very rare in the worldwide orogens. This reveals that the orogen and stable area of the world, the mantle and crust states of the Proterozoic and Phanerozoic are different in tectonic evolvement and dynamic process and that the rapakivi granite of the Qinling-Kunlun is a kind of orogenic granite different from the stable area of the Proterozoic.

它们出现在每一个大的造山旋回晚期，即向另一个构造旋回的转折期，这在世界造山带中是十分罕见的，反映出世界上造山带与稳定区元古宙和显生宙的地慢与地壳状态是不一样的，有着不同的构造演化历史和动力学过程，表明秦岭－昆仑地区的环斑花岗岩是一种有别于元古宙稳定区的造山型环斑花岗岩。

Research on the main rock-forming minerals of Middle Proterozoic Subera Yingfeng rapakivi granite in the North Qaidam Basin tectonic belt indicates the magmatic body exhibits pyterlitic rapakivi texture,and each main mineral is polygenetic.K-feldspar mainly takes the form of oval phenocryst,and exsolved albite stripe is well-developed.

柴北缘构造带中元古代鹰峰环斑花岗岩主要造岩矿物的研究结果表明，该岩体具pyterlitic型环斑结构，各主要矿物均具多世代特征。

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.

通过秦岭－昆仑造山带中的环斑花岗岩同世界元古宙环斑花岗岩的岩石学、岩相学、岩石地球化学和构造环境等方面的对比研究发现，二者具有相同或一致的特征：具环斑结构，属准铝、高钾、富碱岩浆，具双峰式岩浆组合，形成于后碰撞环境，但其地球化学的某些指标、岩浆形成时代和出露的大地构造位置等有一定差异。
