Aeromagnetic Anomalies Of Applied Research In Jiaduo Ling Conversion Of Iron Ore Prediction

With the demandof iron ore resources fornational economy, looking for the decrease of concealed mineral iron deposit has become the important task of mineral prediction. Magnetic prospecting has its unique advantages,It is easy operation, high efficiency, low cost; It is widely used in many areas, is not limited by region, application scope, will ground magnetic measurement data and aeromagnetic anomalies, establish using magnetic measurement, so that the model for iron ore to unknown area iron ore prediction, This paper is focus on the work of summaring typical iron ore bed with magnetic anomaly characteristics and metallogenic regularities related.Through the research area aeromagnetic data analysis, aeromagnetic anomalies processing and conversion, including the extremely (on aeromagnetic), upward continuation, horizontal first-order derivation and vertical first-order derivation of aeromagnetic data, reflects geological and prospecting information (especially in deep) have a more comprehensive understanding is gotten. According to the processing and conversion of prediction result, geological structure (especially concealed workspace analysis tectonic), was deduced for iron ore prediction of direct or indirect prospecting tectonic symbol. A reliable basis. on iron ore prospecting for delineating target is provided by the magnetic anomaly infomation.Various conversion of frequency domain theoretical basis, formulas, data processing, and the realization of applied to Jiaduo ling Bin rock type iron ore prediction area aeromagnetic data of various conversion process, using the above aeromagnetic anomalies conversion processing by the formation of the maps for magnetic field, zoning, fracture division, target area position delineated to provide the basis. Combining witn the geological data, it is concluded that Jiaduoling iron deposit is a magnetic deposit of bin rock type.Three places prospecting target area. are indicate by the characteristics of magnetic anomaly, structural features and metallogenic environment...
