Geologic Reference Library
Our geologic library contains a variety of information about the geology of Maine. Published information from state, federal, and private agencies has been collected and cataloged. The library also contains a wide range of open-file and unpublished maps, progress reports, theses, dissertations, and recent geologic journals. The library is for reference only; material cannot be signed out.
Maine Mineral Collection
A display and reference collection of rocks and minerals is open to the public during office hours. The rock and mineral collection contains specimens from localities in Maine and elsewhere in the country.
Collections of Maine Rocks and Minerals
Several collections of Maine rocks and minerals are available for loan to Maine teachers for periods up to a month. Each collection contains large specimens of 20 rocks and 20 minerals along with a study guide which describes each sample. Because of the size and weight of the collection, it is necessary to pick it up in person and have it signed out to you at our office, and bring the collection back to the Maine Geological Survey when done. Since there are only a few kits, please call first (207-287-7178) to inquire about availability and schedule a pick-up time.
