摘　　要：在野外调查和对已有地质资料进行研究的基础上,阐述了赤峰地区非金属矿成矿背景。分析了非金属矿的时空分布规律:在成矿时代上,中生代最为重要,古生代与前寒武纪次之,新生代成矿较少;在空间分布上,南部内蒙古地轴主要发育变质成因和火山—热液成因的非金属矿产,中部加里东褶皱带的非金属矿产以碳酸盐岩和萤石、玄武岩为主,北部晚华力西褶皱带的非金属矿产既有碳酸盐岩和火山一热液成因类型,也有与矽卡岩有关的成因类型。最后从含矿建造的角度,探讨了优势非金属矿产的找矿潜力。Based on field investigation and existed geological data researching, the background of nonmetallic mine＇s formation in Chifeng area is expatiated. By analysing the temporal and spatial distribution regularity of nonmetallic mine, following conclusion are gotten. The most important metallogenic time is the Mesozoic Era, subordinately the Paleozoic Era and Precambrian, lastly the Cenozoic Era. From the spatial distribution point of view, Inner Mongolian axis mainly develops the metamorphic and volcanic-hydrothermal genesis types of nonmetallic mine. Caledonian fold belt＇s mainly nonmetallic mine are earbonet rock ,fluorite and basalt. In the late Hercynian fold belt not only develops carbonet rock and volcanic-hydrothermal genesis mine, but also develops the genesis type related to skarn. In the end, from the ore-bearing formation point of view, the prospecting potential of preponderant nonmetallic mine is discussed.
