摘要
吉林省铁矿资源贫乏,目前的矿石储量不能满足钢铁业的可持续发展.在成矿地质背景分析的基础上,对区域成矿规律、典型矿床特征及航磁异常、重力异常分析研究,认为吉林省具备铁矿成矿的地质条件,只要科学部署、加大勘查力度,实现铁矿找矿突破是完全可能的.找矿方向应以寻找沉积变质型铁矿为主,兼顾夕卡岩型铁矿及其他新类型,如岩浆型、火山型等.应该加强在吉南地台区、元古宇塔东群出露区、沿深大断裂分布的基性杂岩体及航磁、重力异常叠加区、玄武岩覆盖区及中生代沉积盆地结晶基底的找矿工作.
The iron resources in Jilin Province are not enough to satisfy the sustainable development of steel industry. On the basis of metallogenic geological setting, the regional metallogenic regularities, characteristics of typical deposits, aeromagnetic and gravity abnormity are studied. The result shows an essential condition for iron deposit metallogenesis. The targets of iron ore are suggested at meta-sedimentary type, followed by contaet metasomatic type, magmatic and volcanic types. The areas with aeromagnetic and gravity abnormity in Southern Jilin platform, Proterozoic Tadong group, and basic complex rock body distributed along large deep fault belts, especially basalt covered area and the crystalline basement of Mesozoic sedimentary basin, should by paid more attention.
