The Early Paleozoic Shiti-Shenhe area belongs to the South Qinling orogenic belt and has the characteristics of the so-called “chert-limestone-mudstone” sedimentary edifice in deep-water setting. It was a rifting basin formed in the extensive structural regime, and there coexisted the classic deep-water sedimentation, volcanic exhalative sedimentation and hydrothermal sedimentation, producing the special and unique polymetallic field composed mainly of barite and magnetite. The facies of hydrothermal sedimentary mineralization basin show distinct several-dimensional associations comprising structural deformation, petrologic composition, geochemical signature and features of sedimentary rocks. The analysis and identification show that the third-grade hydrothermal sedimentary mineralization basin is controlled by the syngenetic faults and the volcanic actions, having the geographic features of the sedimentary rocks, association of hydrothermal sedimentary rock, exhalation association, obvious mineralization and distribution of geophysical and geochemical anomalies.
