Research on the application of multi-channel spread-spectrum IP method in mineral exploration
The Xitian mining area in Hunan Province has a good metallogenic background and rich polymetal-lic mineral resources,and it is of great significance to carry out mineral exploration for the development and utiliza-tion of Xitian mineral resources.In this paper,the large-pole multi-channel spread-spectrum IP measurement was carried out in the mining area,the large-pole multi-channel observation arrangement was designed to increase the exploration depth and improve the efficiency of field data collection,and two parallel large-pole multi-channel spread-spectrum IP profiles were deployed,with a total length of 2400 m,and the resistivity profile and amplitude-frequency profile of about 1200 m underground were obtained,and three ore veins were inferred based on geologi-cal data.The large-pole multi-channel spread-spectrum IP method has been applied well in the exploration of polymetallic minerals in Xitian,Hunan Province,which can reflect the IP anomaly caused by tungsten-tin polymetallic ore body,which provides a reference and basis for the development of deep polymetallic mineral resources in the area,and also provides a reference for the exploration of similar minerals.
