Geophysical and geochemical abnormal characteristics and Prospecting Prediction in Xujiazui mining area
Xujiazui copper and iron mining area of Daye City,Hubei Province is located in the northwest of Tonglushan ore field,In recent years,Three new industrial ore bodies were discovered,It was a great progress in prospecting for ore.theⅢ ore body is the main ore body and copper resources reached near-medium size.In the process of prospecting,We collected 1:1 million area gravity and magnetic data and primary halo anomalies data.The CSAMT electrical profiling and logging of geophysical exploration have been carried out.This paper systematically summarizes the physical characteristics of rock ore in the area and plane gravity and magnetic anomaly characteristics and geochemical anomaly characteristics of bedrock and element combination characteristics of ore body.On the basis of the above research results,We have carried out more in-depth data processing and anomaly extraction on the results of planar gravity and magnetic logging,CSAMT,three-component magnetic logging and drilling initial halo.At the same time,We conducted a comprehensive study in conjunction with geological conditions,We proposed a favourable site for prospecting and carry out prospecting prediction.The analysis shows that there is good prospecting potential in the southeast deep contact zone and the vergence direction of the north west ore body.It effectively guides the next step of prospecting work.
