What type of rocks can be dated using radioactive dating.

Radioactive isotopes dating rocks

Clocks in the Rocks - HyperPhysics Concepts.

Radiometric dating is a method used to date rocks based on the known decay rate of radioactive isotopes. This method works because rocks are radioactive. Now, they do not give off enough radiation.

The earth is billions of years old. The most useful methods for measuring the ages of geologic materials are the radiometric methods-the ones that make use of radioactive parent isotopes and their stable daughter products, as preserved in rocks, minerals, or other geologic materials.

Nuclear Chemistry: Half-Lives and Radioactive Dating.

Radiometric dating (often called radioactive dating) is a technique used to date materials such as rocks or carbon, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.

What Is Radioactive Dating, and How Does It Work?

Carbon-14, the radioactive isotope of carbon used in carbon dating has a half-life of 5730 years, so it decays too fast. It can only be used to date fossils younger than about 75,000 years. Potassium-40 on the other hand has a half like of 1.25 billion years and is common in rocks and minerals.

Radiometric Dating: Problems with the Assumptions.

Radiometric Dating is the use of radioactive isotopes to measures the ages of rocks (or, more specifically, of minerals in the rocks). A number of different isotope combinations are used to seek a consistent answer, since all have their own sublties and difficulties that must be intercompared to give a meaningful answer.
