| Abstract: | In order to study the combination of effective geophysical and geochemical prospecting methods in mineral inspection work in arid desert areas and to achieve regional mineral prospecting breakthroughs,the authors conducted the mineral survey work in an arid desert area in the Heiyingshan area of Inner Mongolia.Geophysical and geochemical methods were used in search for copper polymetallic deposits.Geological survey,high-power IP,high-precision magnetic survey at a scale of 1∶10000 and thermomagnetic component soil measurement(1∶50000)were carried out in the survey area.IP anomalies and magnetic anomalies were delineated,and characteristics of multi-element combination were revealed after data processing.The controllable source audio magnetotelluric sounding profiles were arranged in the locations of the IP anomalies and the anomaly concentration places of the elements to determine the downward distribution of the two high conductivity anomalies.The trench reveals that strong silicification,skarnization and malachite mineralization occur at the contact zone between the albite-actinolite-schist mixed with metamorphic quartz sandstone in the Gongpoquan Formation and the marble.The content of Cu and Ag in the samples reaches the boundarygrade.The ore-search prospects in the survey area are good and further work should be carried out. |
