ABSTRACTThe essence of this paper is contained in 6 tables entitled: (1) the 5 groups of minerals and their members, some or all of which occur as essential meteoritic minerals; (2) the essential or Class I meteoritic minerals; (3) the primary accessory or Class II meteoritic minerals; (4) the secondary accessory or Class III meteoritic minerals (including both trace (t) and doubtful (d) minerals); (5) the subclasses of meteorites and their symbols (in the simplified classification of meteorites); and (6) the (2‐dimensional) classificational sequence of meteorites. These tables are described and discussed, and certain conclusions are drawn from them, especially from Table 6. An “Addendum on Certain Subclasses Not Mentioned in Table 5” is included between the main part of the paper and the “Notes and References” a
