| Abstract: | The sedimentary rocks of Silurian, Carboniferous, Permian, Devonian and Triassic are distributed in Qinling area; Devonian and Triassic are the main ore-hosted formation, secondly Silurian, Carboniferous and Permian formation.The gold mineralization is divided into five types: deformation-metamorphic and thermodynamic gold deposit hosted in fine clastic rocks, ductile shear zone - controlled gold deposit hosted in clastic rocks with intercalated limestone, thermal exhalation gold deposit hosted in albite breccia, epithermal gold deposit hosted in clastic-carbonate formation and nappe-controlled gold deposit hosted incarbon-bearing argillaceous rocks. The ore-controlling factors are summarized as uplift of basin margin, denudational fault at margin of thermal uplift,nappe of interface of different strata and multiphase deep-seated fault. |
