应重视地球物理方法在宁乡式铁矿找矿勘查中的应用

摘要

宁乡式铁矿是中国重要的铁矿类型,在找矿勘查中地球物理方法应用几乎是空白.针对两种成因类型的磁铁赤铁矿层,测定了部分磁性、电性参数值,结合少数应用实例综合分析,认为地球物理方法对宁乡式铁矿能取得较好的找矿效果,应在今后的找矿实践中予以应用,这将对宁乡式铁矿特别是隐伏矿找矿具有现实意义.%The Ningxiang-type iron deposit is major iron ore type and widely-spreading in China.The authors find two genetic types of magnetic-hematite beds and determine part of the magnetic,electrical parameter values,based on the some application examples of integrated analysis results,the authors think geophysical method can achieve better results for prospecting of Ningxiang type iron deposits and should be applied in practice in future prospecting.This will be of practical significance to the Ningxiang type iron deposit,especially concealed ore deposit prospecting.
