| 中文摘要: |
| 安徽铜山铜矿已有近50年的开发历史。为建立具有预测能力新成矿模式，对该矿床的地质背景、矿体地质特征、控矿构造以及矿体定位空间的分布规律和形成机制进行了深入研究。认为矿体受与接触带套合的波状起伏的伸展断层控制，矿体的位置及规模受接触带断层的不均匀扩容制约。基于这些认识，建立了波状接触带-断层伸展剪切扩容构造控矿理论模式。根据这一理论模式，预测矿床的深部存在大规模隐伏矿体。钻探结果证实了这一预测结论，表明这一新的成矿理论模式将在铜山的深部找矿勘查中发挥重要作用。 |
| 英文摘要: |
| This study analyzed the geological setting, orebody features, and ore-controlling structures of the Tongshan copper deposit in Anhui Province. It also revealed the distribution regularity and formation mechanism of orebodies in this mine. The aim was to establish a metallogenic model with prediction capability for this deposit which has been explored and mined for almost 50 years. The results show that the orebodies are controlled by the wave-like undulating contact zones that are superposed by extensional faults. The position and scale of ore bodies are constrained by uneven dilation along the waved contact-faults. Based on this understanding, we established a model of orebodies controlled by dilation spaces along the waved contract-faults under extension-shear. This model predicts that there would be large-scale orebodies in the deep portion of the mine. The drilling holes encountered the ore bodies at depths predicted by the model, implying that this novel model would play an important role in searching for deep ore bodies in this mine. |
