Application Research Of Ground High-precision Magnetic Method In Aeromagnetic Anomaly Verification

Ground high-precision Magnetic Method is the most common method ofgeophysical exploration,which is mainly used in the search for iron,lead-zinc,coppermetal the mineral resources. And it is also used in geological structure investigatingand geologic mapping.The thesis introduces in detail ground precision magnetic survey in theaeromagnetic anomaly verification on the basis of comprehensive search and analysisdomestic and foreign means of existing achievements and relevant literatur of theaeromagnetic anomalies verification. Initially proposed and confirmed practicality andeffectiveness of the combination method in which Ground high-precision Magneticmeasurement combined with the field X-ray fluorescence measurements，gamma-ray spectrometry，shallow drill，indoor microbeam and microdomains X-ray mineralprobe measurement， wavelength dispersive X-ray fluorescence spectrometry.Ground high-precision magnetic measurement is primary task of theaeromagnetic anomaly verification, this measurements on the scale of1:10000weremade in Turks work area,XinJiang using WCZ-1proton magnetometer to delineatethe approximate range of the magnetic body. Secondly, From a computationalanalysis of rock body of magnetic parameters of magnetic prospecting combiningbasic knowledge on magnetic data to do smoothing, derivation, reduced to the pole, continuation and inversion. Not only can we get the distribution characteristics ofmagnetic anomalies but also get the approximate physical characteristics of themagnetic rock. Inaddition, provided the necessary prerequisite for developing latework.Finally, Comprehensive analysis explained the cause C-2011-4aeromagneticanomalies point the magnetic anomaly reasons by the combination method,which is ground high-precision magnetic measurement combined with the field X-rayfluorescence measurements，gamma ray spectrometry，shallow drill，microbeam andmicrodomains X-ray mineral probe measurement and wavelength dispersive X-rayfluorescence spectrometry. Clearly stated magnetic anomaly is caused by theremanence of andesite,which in the contact zone of Dahalajun formation andTiemulike formation.The iron content of surface rock samples up to10.34%.
