Abstract: The Lingshan granite complex mainly consists of 4 rock types: (1) coarse porphyritic hornblende-biotite granite (140 Ma); (2) medium-coarse grained biotite granite (127 Ma); (3) medium-fine grained albitized zinnwaldite-bearing granite (100-126 Ma); (4) granite porphyry. In this paper, the petrological characteristics, petrochemical composition and rare earth elements (REE) contents of the various rock types and the REE contents of 5 rock-forming minerals are given. With the aid of petrochemical compositions and REE data the authors have discussed the genesis of the granites. It is postulated that a melt of the granite complex had been derived from Proterozoic phyllite-tuffite by partial melting and that crystal differentiation might have played an important role in the formation of Granite 2 and Granite 3.
