| 摘要: |
| The Geological Characteristics and Metallogenesis of Gold Deposits in Bayanhongor Area, Mongolia |
| Bayankhongor area is located in southern Central Mongolia. Owing to its complex tectonic movement, Bayankhongor area has developed multi-period tectonic magmatic activities and granitiod-related gold deposits. Gold deposits are of quartz vein type, porphyry type and skarn type. Main gold mineralization is related to Permian magnetite-series granitoids, whereas ilmenite-series granitiod-related mineralization is less seen. Ore-forming chronology shows that gold deposits should have been formed earlier than Triassic, i.e., they occurred mainly in Carboniferous and Permian, resulting from the magmatic activity during the tectonic conversion process of the micro-continental collision period. These gold deposits constitute a gold ore belt with the best gold potential in Mongolia. |
