Geochronological studies are one of the very important tool that help in the modelling for the favourability and selecting the geological terrain for uranium exploration in accordance with the existing example. One of the various considerations that apply to the exploration of all types of uranium deposits is “TIMING”, without an idea of age of uranium deposit, age of its host and source rocks, the proper exploration strategy cannot evolve (Cuney, 2008). The uranium deposits of Archean and Proterozoic era are important since they contain >75% of the world’s uranium resources in the form of Paleo Quartz Pebble Conglomerate (QPC) type, Proterozoic unconformity type and Polymetallic Iron Oxide Breccia Complex (IOBC) type of uranium deposits which occur in distinct time and in specific age group of rocks. Age data along with isotopic signature is very important in establishing Precambrian stratigraphy, petrogenesis and crustal evolution in general and understanding genesis of uranium deposits in particular. World over, fifteen types of uranium deposits have been identified (IAEA, 2022) and out of these Proterozoic unconformity related uranium deposits located in Canada are of highest grade and large tonnage. These deposits occur along the unconformity contact during distinct period that is between Lower and Middle Proterozoic e.g. Cigar lake uranium deposit, Canada, c. 1300 Ma, which has multiple younger remobilisation ages up to 200 Ma, resulting into one of the highest grade uranium deposit, at Mac Arther lake (19% U3O8). Present discussion on geochronological (Pb-Pb, U-Pb and Sm-Nd) and isotope geochemical studies on important Indian uranium deposits is aimed to understand its temporal correlation with that of other deposits of the world and also have an idea about the source rock.
