A Review on PGEs Geochemical Reference Materials in the World
The analysis of platinum group elements (PGEs) is one of the most challenging tasks in geoanalysis. It is also the bottleneck for the investigation, evaluation and related research of PGEs minerals and natural resources. In this paper, the authors review all certified values of PGEs in four series, totaling 21, of PGEs reference materials (ultrabasic rocks and chromite ores PGEs reference materials, geochemical PGEs reference materials, ores PGEs reference materials and Co-rich seamount crust PGEs reference materials) and other geochemical reference materials prepared by
