U-Pb ages of zircon in sediments are used to determine the provenance of the sediments. Fission-track analysis is useful in determining the thermal history of a sample or region.This method should also be applied only to minerals that remained in a closed system with no loss or gain of the parent or daughter isotope.Uranium-Lead Dating Uranium-Lead (U-Pb) dating is the most reliable method for dating Quaternary sedimentary carbonate and silica, and fossils particulary outside the range of radiocarbon.If the rock containing these minerals is heated, the tracks will begin to disappear.

If the rock is heated high enough, 120C for apatite, all tracks will disappear.In contrast to a method such as Radiocarbon dating, which measures the disappearance of a substance, K-Ar dating measures the accumulation of Argon in a substance from the decomposition of potassium.
