Abstract: The Hongqiling nickel orefield in Jilin Province is one of the significant mineralizing concentration zones of magmatic copper-nickel sulfide deposits in China. Of the three mafic-ultramafic rock belts outcropped in the area, some contain copper-nickel ore, while the others do not. Comparing the data from recent documents of prospecting for resourcescrisis mines across the country and the relationship between structural control, lithofacies control, mineralization and types of rocks, this paper summarizes the prospecting indicators in the mafic-ultramafic rocks in this area, to provide theoretical basis for the searching of concealed rocks and the evaluation of mineralization around the area in the future.
