The mineralization of wolframite and molybdenite mainly occurs within aplite and granite porphyry, with minor occurrences in hornfels. Twenty wolframite vein ore bodies have been identified in the mine, with an average grade of 1.25% WO3 and an estimated resource of 18,500 t of WO3. Additionally, minor scheelite ore bodies in the Xiuning Formation have been observed, with an average grade of 0.153% WO3. The host rock experienced extensive hydrothermal alterations in the Langcun deposit, including K-feldsparization, silicification, sericitization, chloritization, epidotization, and carbonation, among which silicification and sericitization are particularly associated with W and Mo mineralization. The deposit suggests four continuous mineralization stages:
Stage I: Quartz–K-feldspar stage.
Stage II: Quartz–sericite–molybdenite stage.
Stage III: Quartz–chlorite–pyrite stage.
Stage IV: Calcite stage.

The petrographic observation shows that the daughter minerals in type-LDV inclusions at the early stage are both transparent and opaque. SEM analysis results reveal that the daughter minerals include the following: (1) halite,(2) strontianite,(3) ilmenite, (4) sericite occurs with other daughter minerals, such as calcite, chalcopyrite, and pyrite, 5) chalcopyrite, can coexist with sericite and rhodochrosite and (6) pyrite.
