An additional problem with carbon-14 dates from archeological sites is known as the "old wood" problem. In archaeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates (coins and written history ). This is a radiometric technique since it is based on radioactive decay. Archaeology: Down to Earth (Fifth edition.

When an organism dies, control over the configuration of the amino acids ceases, and sexanzeigen niedersachsen the ratio of D to L moves from a value near 0 towards an equilibrium value near 1, a process called racemization. This process frees electrons within minerals that remain caught within the item. However, it can be used to confirm the antiquity of an item. "Amino Acid Racemization on Mars: Implications for the Preservation of Biomolecules from an Extinct Martian Biota" (PDF). During sediment transport, exposure to sunlight 'zeros' the luminescence signal. The half-life of potassium-40.3 billion years, far longer than that of carbon-14, allowing much older samples to be dated.

Argon, a noble gas, is not commonly incorporated into such samples except when produced in situ through radioactive decay. The date measured reveals the last time that the object was heated past the closure temperature at which the trapped argon can escape the lattice. 4 Amino acid dating edit Main article: Amino acid dating Amino acid dating is a dating technique used to estimate the age of a specimen in paleobiology, archaeology, forensic science, taphonomy, sedimentary geology and other fields.

Cosmic radiation entering the earths atmosphere produces carbon-14, and plants take in carbon-14 as they fix carbon dioxide. Radiation levels do not remain constant over time. Thus, measuring the ratio of D to L in a sample enables one to estimate how long ago the specimen died. "Archaeological Applications of Amino Acid Racemization".
