Carbon 14 dating is the best known example of radiometric dating, but there are many others.
Another example of radiometric dating is the dating of the age of geological formations on earth. The oldest known rocks on the earth that have been analyzed, have been dated back some 4.404 billion years.
Two major dating methods applied to artifacts and fossils are stratagraphic dating (based upon the particular layer of rock of sediment in which the object is found) or radiometric dating (which is based on the decay rates of certain radioactive isotopes). The type of radiometric dating used depends greatly on the approximate time period you are studying and so varies depending on if the material you are studying is an artifact or a fossil. The method most commonly used in archaeology is carbon dating.
If radioactive decay rates were not constant, the passage of time inferred from radiometric dating would be inaccurate. Changes in decay rates would affect the ratio of parent to daughter isotopes used in dating, leading to flawed age calculations. The fundamental assumption of radiometric dating is that decay rates remain constant over time.
Carbon-14 dating would be the most appropriate radiometric dating method for dating artifacts found at effigy mounds. This method is commonly used for dating organic materials such as wood, charcoal, or bone, which are typically found in archaeological sites like effigy mounds.
Radiometric dating is possible because the rates of decay of radioactive isotopes are constant and predictable over time. By measuring the amount of remaining parent and daughter isotopes in a sample, scientists can determine the age of the sample.
The most often used radioactive elements used in radiometric dating are carbon, potassium-argon and uranium-lead.Other elements are not, or very rarely used.

Carbon-14 is an example of radioactive dating.
Radiometric dating is the term for a method to determine the age of an object based on the concentration of a particular radioactive isotope contained within it. Example sentence:One of the early tests of radiometric dating was to estimate the age of the wood from an ancient Egyptian artifact, for which the age was already known from historical documents.
Radio metric dating.
Radiometric dating is the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and can be used to date a wide range of natural and man-made materials.

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.
Yes, carbon-14 dating is a form of radiometric dating. It relies on measuring the decay of carbon-14 isotopes in organic materials to determine their age.
Radiometric measurement is based on the decay of certain elements, the rate of which is a known scientific fact.
Archaeology
Radiometric dating is least useful for dating sedimentary rocks because they are formed from the accumulation of sediments, making it difficult to determine the original isotopic composition.
Radiometric dating can give us the absolute age of the rock. Trace fossils and the Law of Superposition can only provide the relative age of the rock. Radiometric dating is far more specific in formation analysis.
