Radio potassium dating is a type of relative geology
radiocarbon dating also referred to as carbon dating or carbon14 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 by willard libby who received the nobel prize in chemistry for his work in 1960 it is based on the fact that radiocarbon 14.
Chronological dating or simply dating is the process of attributing to an object or event a date in the past allowing such object or event to be located in a previously established chronologythis usually requires what is commonly known as a dating method several dating methods exist depending on different criteria and techniques and some very well known examples of disciplines using.
