摘要 50年来,我国铁矿勘查工作取得了丰硕成果,经历了露头矿到隐伏矿的找矿、从经验找矿到理论指导找矿的过程。在勘查过程中,通过不断地研究和总结,对沉积变质型铁矿提出了向斜控矿模式及斜磁化模型;对接触交代型铁矿提出了"邯邢式"模式和低缓磁异常模型,以及"大冶式"模式和次级磁异常模型;对与陆相火山岩有关的铁矿提出了"玢岩型"模式及磁异常模型。同时在勘查过程中提出了综合找矿,综合评价的认识。这些勘查理论的建立对我国铁矿勘查工作起到了巨大的推动作用,初步统计,以这些理论为指导,发现了多个超大型和大中型铁矿,新增储量达150亿t以上,为我国钢铁工业的发展提供了资源保障。 In the past 50 years, great achievements and many iron deposits have been obtained by the exploration of iron deposits in China. The course of ore-search is changed from outcrop ores to hidden ores under the direction of empirical prospecting into theoretical prospecting methods. During exploration of iron deposits some metallogenic models are established such as synclinal ore-control model and diagonal occurrence model corresponding to iron deposits of sedimentary-metamorphic type; ' Hanxing type' model and rolling magnetic anomaly model, ' Daye type' model and secondary magnetic anomaly model corresponding to contact metasomatic iron deposits type; porphytite model and magnetic anomaly model corresponding to continental volcanic rock type through incessant analysis and investigation. The cognition of integrated prospecting and evaluation are also put forward while the exploration of iron deposits. The establishment of the exploration theories plays a very important role for the development of iron exploration in China. Then, according to pri- mary statistic, many super large-scale and large-middle scale iron mines have been detected with added reserves of 15 billion tons, offeting a guarantee for the progress of iron and steel industry.
