Free 5-day trial Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.
Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson. As we age, our hair turns gray, our skin wrinkles and our gait slows.
The radiocarbon method was developed by a team of scientists led by the late Professor Willard F.
Libby of the University of Chicago in immediate post-WW2 years.
Desmond Clark (1979) wrote that were it not for radiocarbon dating, "we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation" (Clark, 1979:7).
Writing of the European Upper Palaeolithic, Movius (1960) concluded that "time alone is the lens that can throw it into focus".
Paleolithic is a word that comes from the two Greek words The first stone tools were used to meet people's three basic needs of food, shelter, and clothing.
These were difficult times; there were no stores to buy food, and people had to cooperate in small groups to make clothing and shelter.
Flaking involves using a hammer stone to form sharp edges on an object stone by striking it on its sides.
Nyerup's words illustrate poignantly the critical power and importance of dating; to order time.
Radiocarbon dating has been one of the most significant discoveries in 20th century science.
Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.
Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.
