Cishan Migmatitic granite occurs in the Shancaoyu liormation of the Tai- shan Group and extends from NW to SE. The pluton can be divided into three belts from north to south; 1) Porphyric migmatitic granite belt, 2) medium- grained migmatitic granite belt, 3) Moshishan migmatite belt. There are two types of migmatites in the Moshishan migmatite belt; 1) homogeneous migmatite, which had been formed before the formation of the Cishan migmatitic granite, 2) marginal migmatite, which was formed in the course of the pluton emplacement. Homogeneous migmatite inherit chemically biotite leptynite characters. Ho- mogeneous migmatite, medium-grained and porphyric migmatitic granites are chemically same. There are a lot of remnants of biotite leptynite in the homoge- neous migmatite and migmatitic granites, and there are systematically changing of zircon traits and accessory mineral associations in these rocks mentioned above. It is suggested that homogeneous migmatite is formed from biotite leptynite by migmatization, Cishan pluton is formed from homogeneous migmatite by me- ping under closed system conditions, and the microcline porphyric crystal in porphyric migmatitic granite is formed in the later of the magma evolution.
