Interpretation Of Magnetic Anomaly In Halaganlawusu,Inner Mongolia

In recent years,from local and foreign mineral exploration work we can see that the geological prospecting work has been focusing on indirect inference theory of prospecting,high-precision magnetic survey plays an increasing role in the indirect prospecting areas.Studies of Halaganlawusu in Inner Mongolia are relatively low,in this paper,we mainly describe and analyze the applications of high-precision magnetic in the survey of Halaganlawusu.Halaganlawusu is located in the western margin of North China,which is an important part of Langshan-Zhaiertaishan ore concentration area,has a highly favorable regional mineralization background and ore-forming conditions.1:25000 high-precision magnetic measurements has been carried out in the area,which divided the region into three cells,then the data from the field measurement is processed by a serials of methods,including grid,sleek,filtering,analytical continuation and derivative conversion,etc,through which the interference information is suppressed while the deep anomaly is highlighted.Based on the data processing,we delineated the magnetic anomaly area and made an explanation of them,also determined the cause of the magnetic anomalies,meanwhile we concluded the distribution characteristics of concealed ore in the ground,including concealed magnetic body shape,depth,width,and so on,by using the method of semi-quantitative.Finally,combined with the geological and geochemical characteristics of the region and adjacent areas,we made a comprehensive mineral prediction and delineated mineralization prospects,which provides some beneficial information for subsequent mineral exploration and Summarizes some related geological conditions and geological background.In conclusion,all of those provide more favorable information to the peripheral and the deep prospecting work;it can be seen that high-precision magnetic survey has an important guiding significance for future exploration work in this area.
