Uranium-lead dating would be the best technique for dating volcanic rock containing uranium. This method is commonly used for dating ancient rocks due to the long half-lives of uranium isotopes and the presence of lead isotopes as decay products that allow for precise age determination.
Uranium-lead dating is often used for dating very old rocks, as it has a long half-life of about 4.5 billion years. This allows for dating rocks that are millions to billions of years old with good accuracy.
The technique used to date an object by examining the decay of uranium is called uranium-lead dating. This method relies on the radioactive decay of uranium isotopes (primarily Uranium-238 and Uranium-235) into stable lead isotopes over time. By measuring the ratio of uranium to lead in a sample, scientists can determine its age, with this technique being particularly useful for dating ancient rocks and minerals. It is one of the most reliable and widely used methods for geological dating due to its long half-life and the stability of lead isotopes.
Uranium isotopes, particularly Uranium-238 and Uranium-235, are often used in radiometric dating because they have long half-lives, allowing for the dating of geological formations that are billions of years old. Unlike carbon-14, which is effective for dating more recent organic material (up to about 50,000 years), uranium isotopes can provide age estimates for much older rocks and minerals. Additionally, the decay products of uranium isotopes, such as lead, allow for precise measurements that enhance the accuracy of age determinations in the context of Earth's history.
Uranium-238 dating is better than carbon-14 dating for dating older geological samples because its half-life is much longer (4.5 billion years compared to 5,730 years for carbon-14). This makes it ideal for dating rocks that are billions of years old, whereas carbon-14 dating is best suited for more recent materials up to about 50,000 years old.
Uranium dating methods were not used for fossils dating.

Uranium-lead dating would be the best technique for dating volcanic rock containing uranium. This method is commonly used for dating ancient rocks due to the long half-lives of uranium isotopes and the presence of lead isotopes as decay products that allow for precise age determination.
The uranium-lead dating equation is used to calculate the age of rocks and minerals by measuring the ratio of uranium to lead isotopes in a sample. This method is commonly used in geology to determine the age of Earth's oldest rocks.

Four types of radiometric dating are potassium-argon dating, uranium-lead dating, carbon-14 dating, and rubidium-strontium dating. These methods are commonly used to determine the age of rocks and fossils based on the decay of radioactive isotopes.
Uranium-lead dating is commonly used to date rocks. By measuring the ratio of uranium to lead in a rock sample, scientists can calculate its age based on the known decay rate of uranium isotopes.
