     Dongjiangkou and Zhashui granites are located in southern Shangdan fault of the south Qinling Mountains. The systematic mineralogical characteristics of Dongjiangkou and Zhashui rocks and the rocks-forming p-Testi mates were investigated by means of petrological observation, electron microprobe analysis and scanned electron microscope (SEM). The results demonstrate that porphyroid granodiorite and porphyroid granite are composed of quartz, plagioclase(oligoclase), K-feldspar, magnesiohornblende and magnesian biotite, whereas the accessory minerals include zircons, sphene, magnetite and apatite. It can be inferred that the variations of magma composition account for the zoned structure and rapakivi texture in minerals.
