The Fengxian coal-based graphite deposit in Shaanxi province is located in the southern western section of the Northern Qinling Massif in Shaanxi Province and is an important graphite metallogenic belt in the Qinling massif. The results show that the main structural styles of the graphite deposit in Fengxian county, Shaanxi province are “S” - type folds, nappe structure and superimposed fold. After mineralization, it has experienced at least two strong tectonic movements. In the early stage, the compressive stress is dominated by near-NS direction, while in the later stage, the compressive stress is dominated by NWW direction, which is superimposed with the near-East-west fold. Combined with the characteristics of structural ore control, it is found that the focus of ore prospecting in the study area lies in the 5th and 6th strata of Caoliangyi Formation, east of Laochang.
