北山内蒙古地区铁矿成矿特征及其找矿前景

北山地区是中国一个重要的成矿区,内蒙古西部是该成矿区的一部分,其中矿产资源丰富.目前已发现的矿种中,以铁矿规模最大、类型最复杂、矿点最多,但由于地表条件较差,其工作程度均较低.作者对该区铁矿资源的成矿规律、潜力评价等方面开展了大量工作,首次将该区铁矿床划分为6大类型,并对每类铁矿床的成矿特征、成矿环境等进行了较详细的研究.从地质历史发展角度,对各个时期铁矿床的形成背景、成矿条件等做了深入分析,指出了北山内蒙古地区铁矿的找矿方向,这对该区今后找矿工作具有指导意义.

Iron metallogenic characteristics and prospecting potential of Beishan area, Inner Mongolia

As a part of Beishan area, an important metallogenic area in China, western Inner Mongolia has abundant mineral resources. Of all the mineral species discovered in this area, iron is the largest in scale, the most complex in metallogenic type, and the most numerous in number of ore spots. Because of the poor outer conditions,geological work has been rather insufficient. Based on a lot of research work on metallogenic regularity and potential evaluation of iron ore resources, the authors divided the iron ore deposits into six types and made detailed investigations into the ore-forming characteristics and metallogenic environment of each type. From the angle of geological history and development, the authors deeply analyzed the iron metallogenic environment and conditions of each epoch and, on such a basis, pointed out the orientation of iron ore prospecting in Beishan area of Inner Mongolia. The work done by the authors has an important guiding significance for future prospecting work in this area.
