High Precision Magnetic Survey And Application Research On A Vanadium Titanium Magnetite In Sichuan Area

Magnetic prospecting mehod is a relatively mature and widely used geophysicaltechniques.In addition todetecting the magnetic geologic body directly,high precisionmagnetic survey can solve more geological problems. Without magnetic surveypremise for some geological body or geological problems,we can look for parageneticmineral,ore-controlling structure and alteration of surrounding rock which canproduce weak magnetic anomaly,based on geological and geophysical model,tosolve geological problem indirectly such as structure research, geological mapping,survey geological problems in prospecting, mining exploration, ect.High precisionmagnetic survey data is also important information for metallogenicprediction work.In this article, through the work area of field data acquisition and indoor useSurfer, Mapgis software to analyze the data after processing, such as the study areadelineated the20abnormal high precision magnetic survey and number of abnormal,by combining with the existing engineering data inversion and forward more detailedto make qualitative and quantitative analysis, the local anomalies of regionalgeological structure and occurrence of ore bodies to explain inference, provide thebasis for drilling verification. Further in the deep orebody in the deep part explorationcontrol exploration research work.Through this research work mainly made the following findings:1. Completed precision magnetic survey work in therock mass and surroundingground of the study area,there is a deeper understanding of basic-ultrabasicrock,which obviously play a guiding role in the following exploration work.2. Local discontinuous area Previous work area to get old and magnetic surveydata, this work USES the higher accuracy of RTK measurement equipmentarrangement, through comparison of old and new data fusion research, to explain thegeophysical data validation in the past, further pinpoint the location.3. In this paper,20magnetic anomalies in some of the local anomalies wereexplained more detailed in-depth comprehensive processing through the forward,inverse analysis methods such as mathematical physics, geology, geophysical datacomparison method technology, and three-component borehole magnetic survey Technical, on the interpretation of magnetic data inferred mineralization model forthe survey area were discussed, a clear sign prospecting, ore space shape more clarity,and the next step and put forward constructive comments.
