Report (1980) on Three GIT‐IWG Rock Reference Samples: Anorthosite from Greenland, AN‐G; Basalte d'Essey‐la‐Côte, BE‐N; Granite de Beauvoir, MA‐N
Three rock reference samples, Anorthosite AN‐G, Basalt BE‐N and Granite MA‐N were analysed for their chemical composition by 122 laboratories belonging to the International Working Group “Analytical Standards of Minerals, Ores and Rocks” (IWG). 243 analysts took part in this first collaborative stud...

| Summary: | Three rock reference samples, Anorthosite AN‐G, Basalt BE‐N and Granite MA‐N were analysed for their chemical composition by 122 laboratories belonging to the International Working Group “Analytical Standards of Minerals, Ores and Rocks” (IWG). 243 analysts took part in this first collaborative study which lasted only nine months, from June 1979 to March 1980. Despite this very short period, it has been possible to harvest over 6000 units of analytical data on major, minor and 53 trace elements. This excellent performance of the IWG members has rendered possible the chemical characterization of the three samples for not only the usual major and minor elements but also for 30 trace elements. This first study by the IWG Members demonstrates well their immense analytical potential and is exemplary in many respects. |
