The Application Research Of Magnetic Exploration In Iron Survey And Seek In Dushikou, Chicheng Country, Hebei Province

Magnetic prospecting is a geophysics method which research the distribution rulesof geologic structure and mineral resource or other survey objects though theobservation and the analysis of magnetic difference of the rock, the ore or the othersurvey object. It plays an irreplaceable role in seeking for the magnetite and the paragenesis magnetic minerals. With the development of the investigation miningtechnology and the mineral reduce, prospecting in the depth portion and periphery ofmines attracted more and more attention, which need higher precision of dataprocessing.In this paper, we investigate the aeromagnetic abnormity in Dushikou,Chichengcountry,Hebei province through magnetic prospecting, and process the data of magneticprospecting. The data processing include smoothing、filtering、continuation、reductionto the pole、component conversion、forward and inverse and so on, for the sake ofmultiple maps for interpretation of magnetic anomaly. Then using the processing result,we investigate the correlation of aeromagnetic abnormity、volcanic rock and the ironresources, verify the aeromagnetic abnormity,and orientate the aeromagneticabnormity accurately.By the comparison of the results of data processing with different processingparameters, we research the influence of the processing parameter, and to divide thelocal anomalies and regional anomalies accurately. At last, we deduce the magneticanomaly combined with geologic and drilling data, to search the geological cause foranomaly, and to make sure whether iron resources exists. The research could providetechnical data and useful achievements for Ore Exploration in the north of Hebeiprovince, and produce up-to-date and basic information for seeking hidden ironresources in volcanic area.
