Geology forms the basis of much of the subject matter about our physical earth. It is the key to a better understanding of the minerals and soils we use to sustain and improve human life on earth. If you have ever wondered why mountains exist, why a river follows a particular course or why some farmland is more productive the answer to your questions will be found in the subject of Geology.
United States Geology is a generalized view of the Geology of the United States.
State Level Geology Maps are available for all 48 contiguous states. These interactive maps present basic geology and other more detailed geologic data as it is available by state. Faults, dikes, higher resolution geology and localized geological studies can be found on some state maps.
Use our Geospatial Query function on all geology maps to query the USGS National Geologic Map Database and access geologic maps and reports for your area of interest.
This feature provides single click access to all Bedrock and Surficial Geologic Maps of various scales listed in the NGMDB catalog.
Land Matters Geologic Maps do not use traditional color based legends. These statewide maps are created from the combination of multiple localized studies. The classification of geologic formations is not standardized and color coded digital representation of these hundreds of classes is not effective.
The best way to present this geologic data is to provide direct access to the details of each individual feature.
Choose the Identify Tool and Click on the geologic feature you would like to know about. The results window will return basic information on the geologic classification you have selected. CLICK the link to read the full details, including map source and unit source references from the USGS
Click on a category on the right hand menu. A list will open below the menu item. When you scroll over the list items they will highlight in green. Click on the highlighted item of your choice and the map for that item will open in a new window.
