中文摘要:
      【】  文章在数十年的地质勘查与矿山探采资料的基础上,对渣滓溪大型脉状充填锑矿床的控矿构造与成矿作用做了详细阐述。矿床主要产于区域性2条NE向逆冲断层所挟持的抬升断块内,矿脉则无例外的均赋存于矿区NWW向F3导矿断层上盘之成组成带分布的次级NW-NWW向的扭性断裂面内。构造的特点和发展过程是:先在反扭挤压条件下形成,尔后顺扭上隆,在引张条件下张开和充填。研究表明,不同级次的构造彼此间具有良好的连通性,组成一个复杂的构造网,促使矿液上升、分配和沉淀,并逐级逐次地控制着矿床、矿脉和矿体的成生与分布。成矿具有沿倾向发育较深、侧伏延伸和柱状富集的特点。构造动力成矿作用是形成渣滓溪锑矿床柱板状矿体垂向延深超千米的主要因素。
英文摘要:
      Based on the prospecting reports and the mining producting data, detailing deseription the ore controlling structure and metallization of a large filling veins Sb deposit in Zhazixi. The deposit located between the 2 regional NE trend pressure-shear uplift fault block, NWW trend F3 is ore-leading fault, and the ore-veins occurres in F3 hanging wall, as group and belt distributed subsidiary NW-NWW trend shear plane, the space distribution evolution process of the different rank structure, that and governing ore bodies and veins generated and developed. At the start, anti-pressure shear come about, after the cis-shear upheaval, proced from the tension fissure and filling. The research shows that the different rank of structures excellent connectivity each other, composed the complicated structural network, take on ore-fluid rising up and setting. The deposit behave development of ore-body towart dipping, lateral trend extended and rich column of features. The prismatic ore-bodies extends vertically to for 1000m more than author consider that the structure is main ore-forming factor.
