| 中文摘要: |
| 秦岭地区沉岩包括扬子地台北缘志留纪裂陷沉积到晚古生代被动大陆边缘断陷－拗陷盆地沉积和二叠纪裂陷沉积。现有勘查资料表明秦岭地区沉积岩容矿金矿大多集中在泥盆系和三叠系，少量分布在志留系，石炭系和二叠系。 |
| 英文摘要: |
| 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. |
