Mineralogy and geochemistry suggest that the Shipingchuan K-feldspar granite intrusion is a highly fractionated I-typegranite.
矿物组成及地球化学特征显示石平川岩体为高演化I型花岗岩。

This has significant implications for TTG petrogenesis, I-typegranite origin and continental crust evolution.
这对TTG岩石的成因、I型花岗岩的形成以及陆壳成分的演化都有着重要的意义。

The Fe content of Qinling rock body is relatively lower, only 0.62. The petro-geochemical for determining the genesis not only has A-type, but also has I-typegranite characteristics.
