The age dating strategy depends on the type of formation (magmatic, metamorphic or sedimentary), the sample composition and the age of formation. The concentration of the mother and daughter isotopes, as well as the apparent age can be determined with high precision. In many cases, however, the determined age may not be the real age of the geological event. The apparent age may be affected by the post-depositional or post-formation history of the rocks. Natural contamination of chemical sediments with detrital material can also affect the results of dating of diagenesis.

Advice concerning dating strategies and interpretation of data is provided as required. Discounts may be applicable for large age dating programs. For more information, please contact geochronology@actlabs.com
