Abstract: Located in Suichang, Zhejiang Province, Zhilingtou deposit is a large gold deposit on the southeastern coast of China. Its wall rock alterations are widespread in Zhilingtou gold deposit, such as silicification, sericitization, chloritization, pyritization, calcitization and siderite manganese mineralization. From ore body to wall rock, the alteration zone can be divided into quartz-rich, beresitization with quartz, sericite, and chlorite zones. In general, the alteration degree fluctuates with the distance to ore bodies, and forms a shape of lens just as the shape of an ore body surrounded. Gold mineralization is associated with quartz, pyrite, and rhodochrosite alterations. Quartz alteration, pyrite alteration, and rhodochrosite alteration degrees have a similar changing trend; while the sercite and chlorite alteration trend is different. In addition, the deposit develops a low degree of calcite alteration. Both gold mineralization and wall rock alteration occurred in the Paleoproterozoic metamorphic rocks of Badu Group, and did not enter overlying Mesozoic volcanic rocks, which indicates that the formation of the deposit has no relation with the Mesozoic volcanic activities. The elemental quantitative analysis showed that Al2O3, TiO2 and P2O5 were inactive components, SiO2, CaO, MnO, Au, Ag, Cu, Pb, Zn, etc. were gathered,and Fe2O3, FeO, MgO, K2O, Na2O, Ba, Sr, etc. were lost from the wall rocks in alteration process. According to the alteration features and stable isotope analysis, we conclude that the primitive hydrothermal ore-forming fluids of the deposit were mainly of magmatic water with enrichment in Si, Ca, Mn, Au, Ag, Cu, Pb, Zn, etc., and some meteoric water were added to the fluids in ore forming process.

Key words: Zhilingtou gold deposit, wall rock alteration, alteration zone, mass transport
