【摘要】 随着我国工业文明和经济实力的迅速发展，为保证钢铁资源持续增长的消费量，必须要充分立足国内发掘铁矿资源潜力，加强铁矿资源的地质勘查力度和相配套的各项研究工作。面临地表矿产和浅部矿产资源储量日益减少的现状，深部矿产的勘查已成为主要方向。研究一套针对深层矿有效的勘探和解释方法，对我国寻找隐伏矿等方面必将带来很大的效益。本论文依托《重、磁方法在山西铁矿和铝土矿勘查中的试验研究》项目，以山西省繁峙石河铁矿试验研究区为例开展重、磁联合勘探铁矿方法试验研究。针对沉积变质型铁矿重磁资料，进行了异常数据的提取、处理、转换、反演及综合解释推断，总结出一套行之有效的物探方法技术组合。本论文是在前人地质及地球物理工作的基础上，充分利用已有的地质资料、钻孔资料等，结合基础地质调查和矿产勘查工作成果，对地球物理异常特征进行定性及定量的解释及推断，利用RGIS软件对典型剖面进行定量2.5D重磁联合反演计算，通过剖面反演进而进行了研究区目标体磁力3D反演模拟与解释，明确了矿床资源的空间分布及其储量预计，为今后寻找具有类似地质条件、矿床类型相同、异常特征相似的其他铁矿起到一定的参考作用。更多还原

【Abstract】 To make sure the consumption of steel resources grows continuely together with therapid developments of industrial civilization and economic power, we need to improvegeological explorations of iron ore resources. Due to the situations that the shallow surfacemines and mineral resources drain eventually,deeper mineral exploration has already becomean important research field.This paper is based on previous geological and geophysical works.Using the existinggravity and magnetic data, dtilling data, geophysical data, and the basic geological andmineral exploration results,we give here the qualitative and quantitative explaination of thegeophysical anomaly characteristics. Using RGIS software,2.5D magnetic data of the typicalsections is inversed,and the3D inversion of the spatial distribution of the resources of ore isobtained, which could be used as references for the future iron ore explosition.This paper relies on the project of 《Experimental research of gravitational and magneticmethod in the exploration of Shanxi iron ore and bauxite》. A iron ore test field in Fanshi xianShanxi province is studied here. We extract, process, transform, inverse and interpretate of thegravitational and magnetic data of the sedimentary metamorphic type of the iron ore, andobtained an effective processing method.To make surethe consumption of steel resources grows continuely together with therapid developments of industrial civilization and economic power, we need to improvegeological explorations of iron ore resources. Due to the situations that the shallow surfacemines and mineral resources drain eventually, deeper mineral exploration has already becomean important research field..更多还原
