| 中文摘要: |
| 锡矿山锑矿田是世界级的超大型矿床，由北往南，由稻草湾、老矿山、童家院、物华、飞水岩五个矿床组成。以往工作的重点放在飞水岩矿床，对矿田北倾伏端Ⅳ号矿体未开展系统研究工作，导致对含矿层位及矿体屏蔽层的认识不足。近年施工的钻孔在北倾伏端——老矿山矿床取得重要突破，首次揭露了赋存于佘田桥组龙口冲砂岩段与棋梓桥组灰岩层间破碎带内富、厚的Ⅳ号工业矿体。通过详细的钻探地质编录、镜下鉴定、岩矿测试等工作，对Ⅳ号矿体含矿层位沉积相及矿体顶部的屏蔽层开展研究，对主要控矿构造产出特征及控矿关系展开讨论，表明Ⅳ号矿体严格受层位及断裂控制，对明确矿田北倾伏端下一步找矿方向有重要指导意义。 |
| 英文摘要: |
| Xikuangshan antimony ore field is a world-class super large deposit, from north to south, by Daocaowan, Laokuangshan, Tongjiayuan, Wuhua, Feishuiyan five deposits. Previous work focused on the Feishuiyan deposit, but no systematic research was carried out on the Ⅳ orebody at the north dip tip of the ore.eld, resulting in insu.cient understanding of ore-bearing horizon and orebody shielding layer. Drilling in recent years has made an important breakthrough in the Laokuangshan deposit at the north dip tip, and revealed for the .rst time the rich and thick industrial orebody Ⅳ occurring in the broken zone between the Longkouchong sandstone member of Shetianqiao Formation and the Qiziqiao limestone layer. Through detailed drilling geological record, microscopic identi.cation, testing, etc, to Ⅳ ore body of ore-bearing bed, the orebody at the top of the shielding layer and sedimentary facies research, the main ore-controlling structure output characteristics and the controlling relationship discussion, suggests Ⅳ ore bodies are strictly controlled by the strata and fracture, it has important guiding signi.cance to de.ne the prospecting direction of the north dip tip of ore .eld. |
