Geochronology & Isotope Geology Studies Back to Laboratory Facilities

Geochronology is the science of determining the age of rocks, fossils, and sediments using signatures inherent in the rocks themselves. Absolute geochronology can be accomplished through radioactive isotopes, whereas relative geochronology...

Laser Ablation Multi Collector Inductively Coupled Plasma mass Spectrometer (LA-MC-ICPMS)

MC-ICPMS is an instrument that measures isotopic ratios that are used in geochemistry, geochronology, and cosmochemistry. A MC-ICPMS is a hybrid mass spectrometer that combines the advantages of superior ionization of an inductively coupled plasma source and the precise measurements of a magnetic sector multicollector mass spectrometer

Isotope Ratio Mass Spectrometer

Isotope Ratio Mass Spectrometry (IRMS) is a specialized technique used to provide information about the geographic, chemical, and biological origins of substances. The ability to determine the source of an organic substance stems from the relative isotopic abundances of the elements which comprise the material

Optically Stimulated Luminescence Dating (OSL)

Optically stimulated luminescence (OSL) is a method for measuring doses from ionizing radiation. It is used in at least two applications: Luminescence dating of ancient materialse latter case thermoluminescence dating is used more often and radiation dosimetry which is the measurement of accumulated radiation dose in the tissues of health care, nuclear, research and other workers, as well as in building materials in regions of nuclear disaster

Radiocarbon Dating

Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon (14. C), a radioactive isotope of carbon.
