Dating methods based on radio active decay of certain elements provide data on near absolute ages. Radio Carbon Dating of Quaternary deposits and archaeological remains is done to understand the chronological sequence of biological events during the past 40,000 years.
Geochronometry started in the Institute with the establishment of Radio Carbon Dating Laboratory as a National facility in 1973. The absolute ages of the strata are obtained by the radiometric dating. The Radio Carbon (C-14) and Fission-Track dating methods are already established. Considering the increasing requirements of Quaternary workers the laboratory further took-up the Liquid Scintillation Counting of Benzene in 1997 using ultra low level counting system 'Quantulus' for more speedy work.
Atomic Absorption Spectrometer is available for elemental analysis which helps in the interpretation of chemical data to infer the climatic changes of the recent past.
