| 摘 要： | 四方山铁矿经历了三期变形。第一期,当太古宙表壳岩形成后,来自东西向挤压作用,地层和矿体(S0)形成近南北向紧密褶皱构造。第二期,来自北西—南东方向挤压作用,使已经变形地层和矿体(S1)又一次变形,形成走向北东—南西叠加褶皱构造,这一期为四方山铁矿主期构造。第三期,来自北—西向和南东向不对称推力作用,使已经历二次变形地层、矿层均形成了S形,使S2又一次变形。 |
| 关 键 词： | 四方山铁矿 表壳岩 变质变形 背斜 向斜 叠加褶皱 |

| Abstract: | Sifangshan iron ore had experienced three phases of deformation. The first period, the strata and ore bodies （S0） occurred near South-North tight folds by pressed from E-W extrusion effect, after the formation of Archean supracrustal rocks, The second stage, deformed the strata and ore bodies（S1） were deformed again , from the North West-South East direction compression, this period was Sifangshan iron main structure. The third stage , the strata and ore bodies which had experienced twice deformation formed an S shape, due to the asymmetric thrust from the North-West and South East direction , so that S2 deformed. once again. |
| Keywords: | Sifangshan iron supracrustal rocks metamorphism and deformation anticline syncline superimposed folds |
