The Glossary of Geology is a primary source for terminology in the field of the geosciences. The Glossary provides access to the more than 39,000 glossary entries contained in the fifth edition of the print glossary.
Users can learn the difference between look-alike pairs, such as sylvanite (a mineral) and sylvinite (a rock); the origin of terms; the meaning of abbreviations and acronyms common in the geoscience vocabulary; the dates many terms were first used; the meaning of certain prefixes; and the preferred term of two or more synonyms. Many Glossary entries contain a syllabification guide and background information.
The Glossary is searchable using terms, words within terms or definitions, categories and Spanish-language equivalents. Boolean operators (and/or/not) are available for each search field. Search fields may also be combined or may be browsed using a pop-up word wheel.
