Geologic Maps

Geologic mapping is central to much of the research at the New Mexico Bureau of Geology & Mineral Resources (NMBGMR). We have several types of maps that portray geologic information at various scales, both as printed maps and as PDF files (most of these files are free to download). Digital map files (GIS products) are available for many of these maps.

See: 'What is a geologic map and what are they used for?' for a discussion of geologic maps or 7.5-minute Geologic Quadrangles for more information about finding detailed geologic maps..


Types of Geologic Maps

But how do I find what I'm looking for?

Searching for geologic or other maps that cover a given area can be complicated because maps may cover unpredicable areas (e.g. quadrangles, counties, study areas, etc.) and be at various scales. Aside from our statewide maps, most of our maps are of 7.5 minute quadrangles (search by name). Another way to locate maps is to use either our Interactive Map Portal or the USGS National Geologic Map Database which catalogs maps in various searchable ways.
