GEOCHEMICAL CHARACTERISTICS AND FORMING MECHANISM OF THE TASIBIKEDUERGEN GRANITE IN THE NURT AREA, ALTAY

The Tasibikeduergen granite is located in the northeast of the Nurt area. Studies on the petrology,petrochemistry and rare-earth element show that the granite belongs to high-K calc-alkaline series. The magma was derived from the middle crust and the material of the granite originated from the crust. The Tasibikeduergen granite was formed in the extrusional environment at Late Caledonian as a result of partial melting of the crust.;
