The results are given for all the determinations made by the co‐operating laboratories of major elements in the six NIMROC rock samples (granite, syenite, lujavrite, norite, pyroxenite and dunite) prepared by the National Institute for Metallurgy in 1966. Relevant statistical data are given for the sets of results for each major constituent, and recommended values for all constituents except Al 2 0 3 , Na 2 0, K 2 0and CO 2 in dunite, Fe 2 O 3 , MgO and CO 2 in the granite, Fe 2 3 and CO 2 in the norite and CO 2 in the pyroxenite. This report and that on the trace and minor elements issued in 1978 complete the revision of the recommended values. It is suggested that analysts should concentrate rather on those constituents for which the results have shown such a wide scatter that they can be of no usc for reference purposes, than on those for which the ualues are fairly well established.
