The Jiaodong area, located in the southeast margin of the North China Craton, has made a major breakthrough in deep prospecting and has become the third largest goldore cluster in the world. The Linglong gold field is the main producing area of typical quartz vein type gold deposits, and it is also one of the earliest areas to explore and develop gold deposits in China. In recent years, the resources of altered rock type gold deposits in the depth have exceeded that of quartz vein type gold deposits. However, there is still a lack of systematic understanding of the spatial distribution of deep ore bodies and the relationship between quartz vein type and altered rock type gold deposits. In this paper, the geological characteristics of the deposit and changes of the orebodies in the depth of the Linglong gold deposit are analyzed in detail, the research results of geochemical characteristics and metallogenic age are summarized, and the relationship between faults and mineralization, the relationship between quartz vein type and altered rock type gold deposit and metallogenic mechanism are discussed. It is found that the altered rock type gold deposit is controlled by the overall gently inclined main fault, and the quartz vein type gold deposit occurs in the steep extensional fracture in the footwall of the main fault. Several altered rock type deposits constitute a giant gold deposit with gold resources of nearly 600 tons. The deposit forms three mineralization enrichment zones within 2500 m vertically. The depth of I- 2 main ore body is between - 44 m and - 2333 m, the maximum strike length is 4750 m, the maximum dip depth is 2430 m, the average thickness of the ore body is 11.50 m, and the average grade of the ore is 3.15 g/t. Based on the previous research results, it is considered that the gold mineralization occurred at ca. 120 Ma. The ore- forming fluid is the hydrothermal solution of H2O- CO2- NaCl±CH4 system under medium- high temperature, low salinity and reduction conditions. Most of the H- O isotopic composition is cast between the magmatic water and the meteoric water line. The S and Pb isotopic characteristics of the ore are similar to those of the host rock. The ore- forming material mainly comes from the lower crust with a small amount of mantle derived components. It is found that the large altered rock type gold ore bodies mainly occur in the parts with the change of fault dip angle, forming a stepped metallogenic model. The reason is that the change of fault dip angle causes the fluctuation of fluid pressure and gold precipitation. The ore body characteristics of quartz vein type and altered rock type gold deposits are obviously different. The latter has slow dip angle, large scale, low grade, and low content of sulfide in the ore, fine particle size of gold minerals, and the occurrence gold minerals is mainly interstitial gold. The geochemical characteristics of the two types are slightly different. The fluid inclusions in the altered rock type are relatively single, and the salinity and temperature are relatively low. The H- O isotopic composition of quartz vein type ore is closer to magmatic water, and the altered rock type ore is inclined to meteoric water. The S isotopic composition of quartz vein type ores is similar to that of Jiaodong rock group, while the S isotopic composition of altered rock type ores is closer to that of Late Mesozoic Magmatic Rocks. These differences show that quartz vein type and altered rock type gold deposits are the products of the same metallogenic event, with different metallogenic methods and different structural positions. The comprehensive analysis shows that the large- scale crust mantle mixed source magmatism in Jiaodong area provides thermodynamic conditions, migration channels and some fluid sources for the activity of ore- forming fluids. The rapid uplift of magma caused detachment faults and related extensional structures in the shallow crust, which provided a favorable space for fluid accumulation and mineralization.
