List K - Sedimentary structures

List K-1  Sedimentary structures - alphabetical list
List K-2  Sedimentary structures - 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 sedimentary structures begins on page xii.

Under Indexing the current indexing practice is given. These notes should be read along with the instructions under the individual terms in the body of the Thesaurus.

Sedimentary structures
Two lists are provided, an hierarchical list and an alphabetical list with a table of the structure type that the specific structure is grouped under. Where the group names do not autopost, it is noted.

Searching
Search for specific or general structure types as applicable.

For specific searches on a structure, use the structure name, truncated to find all variants.

Indexing
Index the specific structure from the alphabetical 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.
