摘要	Metallogenic depth calculation is of great significance to ore deposit theory research and deep ore prospecting. The classical "pressure/specific gravity" calculation method, however, dose not consider the influence of tectonic stress on the mineralization process. Using this classical method, previous researchers had proposed the Jiaodong altered rock type gold deposit was Proterozoic metallogenic deposit with a depth of 6000-8000 m, and the quartz vein type gold deposit was Mesozoic metallogenic deposit located below 3000 m. However, guided by a five-story vertical zoning model established according to the calculation, the actual deep prospecting exploration was not successful. In recent years a new calculation method has been developed gradually, it uses tectonic correction in metallogenic depth calculation by canceling out additional tectonic stress before calculating metallogenic depth. In this paper, we introduce this new method, point out its application conditions and discuss its prediction significance. The application protocol entails (1) determining the metallogenic pattern; (2) conducting field survey on the tectonic deformation lithofacies; (3) measuring the rock/mineral strain, restoring the metallogenic-tectonic stress field, calculating the additional hydrostatic pressure due to tectonic stress; and (4) calculating the metallogenic depth. Using this method, the metallogenic depths of several typical gold deposits in Jiaodong were calculated and the results are: (1) Xiadian, 1979.51-3014.72 m; (2) Jiaojia, 1632.4-2331.6 m; (3) Dayingezhuang, 2775.4-4164.5 m; (4) Xincheng, 1781.29-2750.0 m; and (5) Linglong, 720.55-3454.97 m. Accordingly, the Jiaodong gold deposits are considered belonging to the epithermal shear zone type deposit with a metallogenic depth of 1000-4500 m. Therefore, it is inferred that the main orebody of the typical gold deposits in Jiaodong remains buried in the deep. Combined with the geological, geophysical and geochemical exploration information, we predicted a "second deep enrichment metallogenic zone" of gold deposit in Jiaodong, and this prediction has been confirmed by deep ore exploration effect. © 2022, Editorial Office of Earth Science Frontiers.
