| Abstract: | In the Northern Qinling Mountains there are three igneous rock series: A, B and C series, corresponding to the mantle-derived, the mantle-derived magma contaminated by crust materials, and the crust-mantle mixing genesis types. The systematic changes of the igneous rock series and the genesis types have reflected polycyclic transference features of the crust and mantle materials. |
