- Uranium/lead dating provides most accurate date yet for Earth's largest extinction

Uranium-lead dating techniques have also been applied to other minerals such as calcite/aragonite and other carbonate minerals. These minerals often produce lower precision ages than igneous and metamorphic minerals traditionally used for age dating, but are more common in the geologic record.

(Lead is the final stable product of the Thorium series, so is not used in uranium-lead dating.) The two uranium-lead dates obtained from U and U have different half-lives, so if the date obtained from the two decays are in agreement, this adds confidence to the date.

Uranium-lead Dating,

The reliability of radiometric dating is subject to three unprovable assumptions that every geologist must make when using the radioactive “clock”. Radioactive rocks offer a similar “clock.” Radioactive atoms, such as uranium (the parent isotopes), decay into stable atoms, such as lead (the daughter isotopes), at a measurable rate.
