摘　　要：温都尔庙群铁矿分南带和北带,原始铁矿层为华北板块北缘陆坡带火山喷发-沉积产物,通过构造解析方法,恢复含铁层位及铁矿体构造形态,还原了褶皱控矿过程。研究认为,南带和北带的铁矿带分属于同斜地背斜的南北两翼,为同层褶曲构造现象,经历多期褶皱作用以及后期热液作用改造形成多个矿体并存。The iron deposits of Wenduermiao Group can be divided into southern and Northern belts.The original iron ore layer is the volcanic eruption-sedimentary product of the continental slope belt in the northern margin of the North China platform. By constructing analytic methods,the structure of iron bearing horizon and iron ore body was restored, and restore the process of fond-controlling deposit. The study shows that the iron ore belt in the south and north zone belongs to the north and south wings of the anticline with same isocline. The two belts are of the same layer fold structure phenomenon, many ore bodies coexist through multi-stage fold action and later hydrothermal transformation.
