Digital data, image files, and text files describing data formats and survey procedures for an aeromagnetic survey covering the southwestern portion of Taos County west of the Town of Taos, New Mexico, conducted in October, 2006

Includes all geochemical data generated by each project partnership funded through Earth MRI and will be updated periodically as additional geochemical data from these projects becomes available.

Data from a study intended to explore how well the chemical analysis of water and sediment in an area reflects that of the rock from which the sediments are eroded and through which the water flows.

Geochemical data from selected USGS projects from the 1960s-1980s that were previously not published as digital data. Includes geochemical analyses from 36,498 samples of various types using analytical methods and instruments that were current when those studies were carried out. Data are provided in Microsoft Access, shapefile, and CSV formats.

Magnetotelluric sounding data collected in 2009 in this area to improve understanding of the hydrogeology of the Santa Fe Group and the nature of the sedimentary deposits comprising the principal groundwater aquifers of the Rio Grande rift.

Magnetotelluric sounding data collected in 2007 in this area to improve understanding of the hydrogeology of the Santa Fe Group and the nature of the sedimentary deposits comprising the principal groundwater aquifers of the Rio Grande rift.

Chemistry and geologic information for nearly 30,000 historic ore and ore-related rock samples from mineral deposits and mining districts in the United States. Data are provided in Microsoft Access and CSV formats.

Rock density and magnetic susceptibility measurements of samples drawn from this area. Data are provided in CSV format.

New data incorporated with existing data complete overall coverage of the basin, one of the largest associated with the Rio Grande rift.

Gravity data were collected from 2006 through 2015 to assist in mapping subsurface geology in this area. Includes principal facts for 567 new gravity stations that were acquired to fill in gaps in previously-available gravity data. Data are provided in CSV format.

Data from 102 magnetotelluric (MT) stations collected from 2012 through 2014 in this area to improve regional conductivity models of the western United States.
