摘　　要：目前,我国年钢铁产量快速增长,国内铁矿石供不应求,铁矿石价格快速上扬。铁矿作为北京市重要的矿产资源,保有储量(资源储量中经济可采部分,下同)不足2亿t,可供北京市现有矿山开采40年,形势不容乐观。因此,加强铁矿资源勘查力度,不断开发新的矿产地,是大势所趋。北京地区铁矿找矿方向,是在密云、怀柔北部山区的变质岩中寻找鞍山式铁矿。The annual steel output is increasing rapidly in our country at present and accordingly,domestic iron ore supply falls short of demand on the market,which leads to a sharp rise in the price of iron ore.As an important sort of mineral resources in Beijing,the retainable reserves of iron ore（profitable and being worth mining） is smaller than 2 hundred million tons in Beijing area,which will probably allow a relatively short 40-year exploitation for Beijing＇s existing mining corporations.The situation is tense.It is necessary to enhance the prospecting of iron ore deposits and find new ones so as to meet the steel demand for the iron ore supply.The northern mountain area of Miyun County and Huairou District is rich in metamorphic rocks,which is the main destination for iron ore deposit（AnShan type） exploration in Beijing.
