From the fission track age determination of garnet occurring in copper ore deposits of Khetri copper belt, Rajasthan, it has been possible to reveal the metamorphism of copper ore formations of the area. The fission track age of 831 ± 132m.y. for garnet suggests that the copper ore formations in the region were subjected to a metamorphic episode which coincides with the Delhi Cycle.
