四川拉拉铜矿构造变形与成矿的关系

四川拉拉铜矿是西南地区著名的大型铜矿床，矿区构造复杂，厘清矿区构造期次，能更好把握矿体的分布和演化。经资料收集、野外调查、数据统计及计算分类等，分析了矿区构造特征，并对区内构造运动矢量进行动力学反演，总结矿区构造变形特征，以此推断构造与成矿之间的关系。矿区构造以定向面理、顺层韧性滑动构造、平移断层、逆断层及正断层为主，可分为六期，主要受到NE向、SN向、EW向及NW向的作用力。其中前四期与成矿有重要影响，尤其是韧性剪切带对成矿起到至关重要的作用。 

Relation between Structural Deformation and Mineralization in Lala Copper Deposit,Sichuan

The Lala copper deposit is a well-known large copper deposit in the southwest China. The structure of the Lala copper mine area is complex. To clarify the structural stage of the mine area can better understand the distribution and evolution of the ore body. After data collection, field survey, data statistics and calculation classification, the structural movement vector in the area is dynamically inverted, and the structural deformation characteristics of the mining area are summarized to infer the relationship between the structure and the mineralization. The structure of the mining area is dominated by directional foliation, bedding ductile sliding structure, translational faults, reverse faults and normal faults. After analysis, it can be divided into six stages, which are mainly affected by NE, SN, EW and NW directions. Among them, the first four stages have important influence on mineralization, especially the ductile shear zone plays a vital role in the mineralization.
