AGI's Glossary of Geology is the definitive reference for the geosciences, with over 39,000 authoritative definitions to terms used in the geosciences - including geology, geophysics, hydrology, oceanography, paleontology, mineralogy, and more.

Users of the Glossary of Geology App can both browse the reference alphabetically or do keyword searches with intelligent results based on relevance.

Used by professionals, students, policy-makers, and others with a need to understand the terminology of our planet, the Glossary of Geology, 5th Ed. is now even more accessible as an App designed both for the iphone/ipod as well as the iPad. And since the entire glossary is contained in the app, you can work offline in the library, field, or lab.
