The USGS Radiocarbon Dating laboratory, located in Reston, Virginia, is part of the Eastern Geology and Paleoclimate Science Center. The objective of this lab is to provide prompt, accurate and precise radiocarbon (14C) accelerator mass spectrometry (AMS) analyses on a wide variety of geologic materials in support of Climate and Landscape Change research. Support is also provided to other USGS mission areas as resources permit. Sample selection and analysis is carried out in close contact with project scientists. Established analytical procedures for radiocarbon dating are carefully applied to every sample the laboratory processes. New methods are developed and tested as necessary to meet specific dating needs and to improve the overall accuracy and precision of the lab.
