Mineral-supported microbial functional differentiation across a vertical gradient in a vanadium-titanium magnetite mine.
Vanadium-titanium magnetite (VTM) mines are often associated with metal contamination, organic carbon depletion, and ecological degradation, yet how indigenous microbiomes respond to vertical geochemical heterogeneity remains poorly understood. Here, we investigated a ∼260 m vertical gradient in the Zhulan Iron Mine, C...
