Terminology Do not use or introduce new and atypical terminology if you are not writing a technical paper. Introduction of new stratigraphic groups, formations and members must be exactly explained, including their limitations and should always be well justified, and must be suggested as proposals open to discussion. As a rule, national committees for stratigraphy are responsible for official stratigraphic subdivisions, which must fit much broader concepts than your paper might treat. Equally the introduction of uncommon terminology to underline the importance of your data and conclusions rather leads to confusion of the reader. Terms like ‘‘superbasins’’, ‘‘superoceans’’, ‘‘mega-continents’’, ‘‘mega-elements’’, ‘‘hyper-sequences’’ lack clear definition and should be avoided. A glossary of geology normally offers enough sound and well established alternatives.
