V. Examples and further references

Examples presented in Table 3 have been selected in such a way as to show the flexibility of choice between various formulae (notations) as well as the flexibility in amount of information included or omitted, depending on the purpose of the study. It should be noted that at some stage of simplification the formulae may describe a group of structure types related through common crystal-chemical features rather than a single structure type.

A glossary of the principal English, German, French, Russian and Spanish nomenclature terms used in this report is provided in Table 4 for the convenience of the reader.

 

Table 4: Glossary of the main nomenclature terms used in this report

Thiis Subcommittee has not considered certain aspects of the notation in detail, especially those which deal with very complex topics that are either not yet developed in sufficient detail or to which a number of different approaches exist. In order to assist the reader, the following reference list is given. Many citations contain further extensive reference lists.
