| 摘 要： | 歪头山铁矿屑鞍山式沉积变质铁矿，褶皱、韧性剪切带、断裂是矿区的主要构造形迹。通过构造解析，将矿区鞍山运动中的构造变形划分为3幕。利用共轭节理和断层擦痕反演，对矿区构造应力场进行了定向、定时研究，确定了各期构造应力场。最后，提出了歪头山铁矿“褶皱 韧性剪切带”控矿模式，新模式对矿区的采矿平面设计及寻找可能的漏矿具有指导作用。

| Abstract: | Waitoushan Fe deposit is of the Anshan style sedimentary-metamorphic deposit. Fold, brittle shearing zone and fractures are the main structural features. Structural analysis reveals 3 episodes of deformation in Anshan movement. Inversion of the conjugate joints and striation is used to study orientation and timing of the tectonic stress field and define the stages of the field. Then a new ore-controling model of folding and brittle shear zone is drawn. The model may be helpful to locate the missed ore bodies. |
