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

See: 'What is a geologic map and what are they used for?' for a discussion of geologic maps.

Types of Geologic Maps

• 

  A simplified geologic map of NM.
  Statewide Geologic Maps of New Mexico:
  • The 1:500,000 Geologic Map of New Mexico provides a great overview of the geology of our state.
  • The Geologic Highway Map of New Mexico (1:1,000,000) is perfect for the glove compartment or the saddle bag.
• Geologic maps of 7.5-minute quadrangles:
  • Over a hundred and sixty Open File Geologic Maps have been projects of our STATEMAP Program over the last 14 years. The geologic field work and basic research are a primary source of geoscience information for our staff and other geoscientists throughout the region (see our index of STATEMAP open-filed geologic maps).
  • GM-series geologic maps from the NMBGMR are high-quality offset-printed paper maps. Our open-filed products will migrate to this series following rigorous review and cartographic production.
• Geologic Map compilations (open file reports): These maps reflect a new effort to assemble existing geologic data for an area of importance.  These maps build upon the latest mapping completed in the STATEMAP program.
• Our monograph series are another source for geologic maps (often included as plates) and detailed research.
• Most USGS geologic maps of New Mexico are available from our publications office (contact us to see if a map you need is in stock). You also may be interested in some of the NM-specific USGS map products available for free download.

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 (see above) most of our maps are of 7.5 minute quadrangles (search by name). Another good way to locate maps is to use the USGS National Geologic Map Database that catalogs maps by various search criteria and provides links to downloads when available.
