Our "Top Picks" for geology-specific databases are a good place to start. Use the Tabs (top of this page) for additional resources. A few tips for your research:
1) Want to improve your search's relevance? Combine your subject (fluvial systems, isotope geochemistry, mineralization, etc.) with:
- Formation names--Fountain Formation; Pierre Shale; Dakota Group
- Structural or region--Paradox Basin; Front Range; Beartooth Uplift
- Locations--Jefferson County; Golden quadrangle
- Time periods--Upper Cretaceous; Precambrian
2) Some of your findings are "old"? Geology publications (field studies, observations, etc.) can still be valuable after decades.
3) Does your subject cross disciplines? Consider searching the literature of chemistry, engineering, environmental science.
4) Having trouble finding a specific publication? Check with a librarian--Some works (conference proceedings, field guidebooks, state documents, etc.) are quirky and can be difficult to discover.
