| 摘 要： | 采用构造－沉积综合分析的方法，研究了金顶超大型铅锌矿床成矿的盆地、构造和深部地质背景。研究表明，控矿的古新世－中始新世盆地为走滑拉张盆地，研究区先后经历了古新世－中始新世早期的走滑和拉伸，中始新世－渐新世的挤压推覆和中新世的隆升和走滑，分析了盆地演化、沉积体系、同生断裂活动和逆冲推覆等对金顶超大型铅锌矿床的控制作用，探讨了可能的成矿过程。 |
| 关 键 词： | 走滑拉张盆地 同生断裂 逆冲推覆 成矿过程 沉积体系 铅锌矿床 成矿地质背景 |

| Abstract: | A comprehensive method of tectonic and sedimentation analysis is employed to study the geological setting of basin, tectonics and depth process in the Jinding superlarge Pb Zn deposit. The studies indicate that the basin containing ore deposits is of strike slip extension from Paleocene to Early Middle Eocene, involving strike slip and extension, compression and thrusting nappe, and uplift and strike slip during Paleocene to Early Eocene, Middle Eocene to Oligocene, and Miocene to now, respectively. The effects of the evolution of basin, sedimentary system, activities of synsedimentary fault and thrusting nappe on the formation of the Jinding superlarge Pb Zn deposit, are revealed, and a possible process of mineralization is also suggested. |
| Keywords: | Jinding Pb Zn deposit strike slip extension basin synsedimentary fault thrusting nappe mineralization process |
