List N - Sediments

List N  Sediments - hierarchical list

General notes
These thesaurus lists, lists A-R, are used by GeoRef indexers for selecting index terms and by searchers for additional information not necessarily found in individual term records in the body of the Thesaurus. In most cases, an hierarchical list is given. In some cases, an alphabetical or other list is provided.

The notes under Searching attempt to guide the searcher in the use of the list. Searchers might also read the notes on Indexing for further clues but should be aware that these notes reflect current practice which in some cases differs from past practice. Further notes on specific terms are in the body of the Thesaurus and additional notes on searching are in the GeoRef Thesaurus, 11th edition Introduction section on searching beginning on page x. Information specific to searching and the individual list topics is included, e.g., a section including sediments begins on page xii.

An hierarchical list is provided which includes an indication where the group names do not autopost.  

Where the process sedimentation is stressed, it is also used.

Papers with major emphasis on sediments can be retrieved by searching for sediments. For a thorough search of sediments, use all sediment types in stemmed form, plus the general term, sediments.

For specific searches on a sediment, use the sediment name, stemmed or truncated.

Index the specific sediment from the list with any needed broader terms. If the term does not appear in the list, index it in the singular with a higher level term that does.
