直流激电法于60年代初便在四川开始使用。因方法设备笨重,工作效率低,电源功率有限,使用受到很大的限制,工作多在点上进行。那么,在四川山区用什么电法配合普查金属矿呢?为此,我队于1979年至82年在四川西南山区的赤铁矿、含铬超基性岩、含多金属的碱性超基性岩和铜锡成矿带上开展了交流激电法的试验和找矿工作。前后共作剖面(1∶2千—1∶5千)
The DC method started in Sichuan in the early 1960s. Due to bulky methods and equipment, low efficiency, limited power supply, the use of a great deal of restrictions, more work at the point. So, what kind of electric law in Sichuan mountain census metal mine with it? To this end, our team carried out the AC-Ag method on the hematite, chromic ultrabasic rocks, polymetallic alkaline ultrabasic rocks and copper-tin mineralization belts from 1979 to 1982 in the southwest mountainous area of Sichuan Province Test and prospecting work. Before and after a total cross-section (1: 2 thousand -1: 5 thousand)
