Abstract: Wu long gold deposit hosted in granite and fine-grained diorite dikes, is a typical gold deposit o quartz vein type. Granite and fine-grained diorite dikes in the ore deposit were altered by metallogenic fluid.Based on the altered zoning, the samples of petrochemistry were collected and major and trace elements were analyzed systematically. Calculation of rock mass balance shows that the major elements (SiO2, K2O, P2O5,Fe2O3) in the two typical altered rocks are clearly added into the altered system, and that trace elements (V,Y, Zr, Ni, Co, Sr) assume an increasing and decreasing tendencies in the altered granite and altered dioritdike, respectively. The fluid/rock ratios are 30.17-181.00 and 115.44-692.67 respectively for altered granite and altered diorite dike, they have profoundly effects on metal o genesis.
