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".Radiocarbon dating is used in many fields to learn information about the past conditions of organisms and the environments present on Earth.Radiocarbon dating (usually referred to simply as carbon-14 dating) is a radiometric dating method.Nyerup's words illustrate poignantly the critical power and importance of dating; to order time.

These are are a mixture of different rock samples that have been "welded" together by the impact process.Radiometric dating, often called radioactive dating, is a technique used to determine the age of materials such as rocks.It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.It is the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and it can be used to date a wide range of natural and man-made materials.The best-known radiometric dating techniques include radiocarbon dating, potassium-argon dating, and uranium-lead dating.It uses the naturally occurring radioisotope carbon-14 (14C) to estimate the age of carbon-bearing materials up to about 58,000 to 62,000 years old. Carbon-14 has a relatively short half-life of 5,730 years, meaning that the fraction of carbon-14 in a sample is halved over the course of 5,730 years due to radioactive decay to nitrogen-14.

    Pleasure turned in astonishment and then in fear, when his thick finger popped her cherry, but his strong hands didn\'t let her go until he has fully enjoyed her gorgeous flesh!
