Radiocarbon dating (14 C) is probably the most commonly used numeric dating method for geomorphological research and is outlined in more detail below. The isotopic dating method can also be based on certain cosmogenic nuclides (e.g., 10 Be, 21 Ne, 26 Al, 36 Cl) that form in situ in the upper few meters of the Earth's surface since the cosmic ray flux is attenuated at greater depths.

How Do Scientists Determine the Age of Dinosaur Bones.

Relative dating methods are used to work out the chronological sequence of fossils. They can be applied to fossils found at a particular site and can also be used to make comparisons between sites. Where possible, several different methods are used and each method is repeated to confirm the results obtained and improve accuracy.

The carbon-14 method was developed by the American physicist Willard F. Libby about 1946. It has proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old. The method is widely used by Pleistocene geologists, anthropologists, archaeologists, and investigators in related fields.

Amino Acid Geochronology: This is a relative, and sometimes absolute, dating method that relates the diagenesis of fossil protein preserved in carbonate materials with time (geologic age of the sample) and temperature (long term chemical temperature of the enclosing sediment). Stratigraphic applications of the method have been demonstrated from both marine and non-marine sequences all over.

Everything Worth Knowing About. Scientific Dating Methods.

Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby, who received the Nobel Prize in Chemistry for his work in 1960.
