Ongoing Research and Projects

Reality of Isotopic Dating

Investigating the truthfulness of known isotopic ages of ancient rocks and minerals using computer simulations by subjecting them to the geological histories suggested by others. If truthful, one should be able to reproduce present-day isotopic compositions of those materials on computer.

Isotopic Evolution of crustal and mantle materials

Developing better models to understand isotopic evolution of crustal and mantle material.

‘Truthful’ Ages From Computer Simulations of Zircons

Simulation of natural zircon U-Pb data using computer to suggest alternatives to geological evolution
