| 摘 要： | 赤峰北部大井多金属矿床为裂隙充填型脉状矿床，矿体主要受断裂构造控制，本文用岩组分析方法首次从微观角度对矿床成矿前及成矿期构造裂隙性质进行研究，阐明了矿床内各矿脉的控矿构造特征，此外，对矿床内断裂系统进行应力分析，提出了成矿裂隙的形成机制。

| Abstract: | Dajing polymetallic ore deposit, located in Northren Chifeng, is a vein filling type.The ore bodies are strictly controlled by the fractures.According to the field and laboratory work, especially determinnation of the optical axis of quartzes from the tectonic rock the authors for the first time dealt with fractures of pre-mineralization and fractures of syn-mineralization.In view of the above opinions ore-control structures are summed up.Finally, tectonic stress especially for fractures within the ore depositis analysed.And thena mechanism of formation for mineralization fractures is put out. |
