Most of the chronometric dating methods in use today are radiometric that is to say and zircon crystals are datable with the fission track method. When we apply radiometric dating techniques to zircon crystals, we are generally looking at the decay products of uranium recall that uranium. Zircon (u-th)/he thermochronometry is an established radiometric dating technique used to place temporal constraints on a range of thermally sensitive geological events, such as crustal exhumation, volcanism, meteorite impact, and ore genesis. Scientists recently found the oldest thing on earth, a zircon crystal, and it dates back to 44 billion years ago carbon dating is a helpful tool in order t.
