WebRadiocarbon dating (usually referred to simply as carbon-14 dating) is a radiometric dating method. 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 has two stable, nonradioactive isotopes: carbon-12 (12C) and carbon-13 (13C). WebUsing this chronology, we can then identify when and where a particular sample of wood was from, simply by matching it to our library of tree patterns.

WebThe 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. WebCharcoal, wood, most peat, and textiles typically undergo the acid-alkali-acid (AAA) method before radiocarbon dating. In some literature, this method is called acid-base-acid (ABA). The AAA pretreatment involves washing the samples with hot hydrochloric acid (HCl) followed by a sodium hydroxide (NaOH) wash.
