The Altay area is an important rare metal, non-ferrous metal, gemstone and industrial muscovite metallogenic belt. Based on the 1︰1 000 000 geochemical mapping data across the boundary between China and Mongolia, the authors calculated background values of 69 elements in the catchment sediments. The median values of the dataset after disposable eliminating outliers from the original dataset with X±3S as the critical values were used as estimated values of the geochemical background values. The results show that the geochemical distribution of elements in different geotectonic units is different due to different geological backgrounds. These background values can be used as basic data for comparison for further development and utilization of geochemical mapping data across the boundary between China and Mongolia.
