USGS Geochemical Reference Materials and Certificates
The USGS Geochemical
Reference Materials project provides geochemical reference materials for use
by scientists in all areas of earth science. The majority of USGS reference
materials are based on silicate rocks that were collected from the continential
United States and Hawaii and range in composition from basalt to shale. The
composition of these reference materials has been determined through rigorous
testing procedures by multiple laboratories using a wide variety of analytical
techniques. The reference materials are suitable for use in calibration of
analytical instrumentation, testing analytical methodologies, and for use as
quality control samples. For more information on this program please see our Fact
Sheet.
