APPLICATION OF THE 5-MODE METHOD TO 3 GIT-IWG ROCK REFERENCE SAMPLES

The ''Five-Mode Method'' for evaluation of compiled data has been appl ied to three well-established GIT-IWG rock reference samples : Anortho site AN-G, Basalt BE-N and Granite MA-N, Results are compared to the a ccepted values, and where the two values are not in accord, a new proc edure, the Graphical Moving Mode, is introduced,It is used to provide a clearer picture of the nature of the distribution of the raw data fo r each constituent, and, possibly to demonstrate the advantages of usi ng the modal approach.
