uranium and polonium
You can date rock layers by radioactive dating using half-life in the igneous rock layers that contain radioactive isotopes like uranium or potassium. These isotopes decay at a known rate to stable daughter isotopes, allowing scientists to determine the age of the rock based on the ratio of parent to daughter isotopes present. Sedimentary rock layers cannot be dated directly using radioactive dating due to the possibility of contamination and the absence of radioactive isotopes in the rock itself.
Radioactive dating of rock samples determines the age of rocks from the time it was formed. Geologist determine the age of rocks using radioactive dating. The radioactive dating relies on spontaneous decomposition into other element. The spontaneous decomposition is called radioactive decay.
The most reliable way to determine the age of a rock is through radiometric dating methods, such as carbon-14 dating or uranium-lead dating. These methods measure the decay of radioactive isotopes in the rock to calculate its age with high accuracy.
Sedimentary rock is not original source material, its rock that got ground into sand, settled (usually under water), got buried, and then got heated and squeezed back into a form of rock. Lots of sources.
The heaviest rock in the world is probably the Baobab granite in Australia, which weighs about 1,500 tonnes. This massive rock formation is still attached to the ground and has not been moved from its original location.
A radioactive rock is one which contains traces of radioactive isotopes. These isotopes release radiation in its various forms. Any rock can be radioactive, but in particular igneous rocks tend to have radioactive properties. This is because they may have radon gas trapped in their crystals, which, under pressure, is released (this is why radon gas is used as an indicator of an upcoming earthquake). Radon gas is radioactive, and this causes the rock to be radioactive also.
i think it's plutonium
Their radioactive clock is set when they solidify from magma or lava.

granite
Plutonium is an artificial, radioactive metal.
Rocks in general are not dated, but a fossil would be.
Absolute dating is a radioactive isotope the geologist can use to learn the exact age of the rock.

Most metals are stable and thus not radioactive.
