Zircon dating metamorphic rocks
We also offer bespoke dating of other mineral-isotope systems that may provide solutions to specific problems, including geochronological dating of igneous and metamorphic rocks.
It has been successfully employed in siliciclastic sediments for mapping reservoirs in the basins, tracing sedimentary pathways, recording denudation histories and dating volcano-magmatic events.
This approach identifies characteristic detrital zircon age spectra, compares them with those from other stratigraphic units in the basin and matches them with potential sediment source areas.
Scientists use this method to date rocks that formed from between 1 million to 4.5 billion years ago, and they estimate the Earth is 4.543 billion years old.
The oldest and most reliable method they use is called Uranium-lead (U-Pb) dating.
