How does carbon dating determine the age of fossils

While people are most familiar with carbon dating, carbon dating is rarely applicable to fossils. All of these methods measure the amount of radioactive decay of chemical elements; the decay occurs in a consistent manner, like a clock, over long periods of time. The age that can be calculated by radiometric dating is thus the time at which the rock or mineral cooled to closure temperature. This ratio turns out to be about one 14C atom for every 1 trillion 12C atoms. After an organism has been dead for 60, years, so little carbon is left that accurate dating can not be established. This scheme is used to date old igneous and metamorphic rocks , and has also been used to date lunar samples. The various confounding factors that can adversely affect the accuracy of carbon dating methods are evident in many of the other radioisotope dating methods. For dates up to a few million years micas , tektites glass fragments from volcanic eruptions , and meteorites are best used. If it sounds like circular reasoning, it is because this process in reality is based upon circular reasoning. All ordinary matter is made up of combinations of chemical elements , each with its own atomic number , indicating the number of protons in the atomic nucleus.

    In a hypothetical example, a rock formation contains fossils of a type of brachiopod known to occur between and million years. For since the creation of the world God's invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that men are without excuse.

    It is therefore essential to have as much information as possible about the material being dated and to check for possible signs of alteration. This restriction extends to animals that consume seafood in their diet.

    The proportion of carbon left when the remains of the organism are examined provides an indication of the time elapsed since its death.

    The interpretation of past events is in question. The following illustration demonstrates how the age is estimated using this ratio.

    By measuring the ratio of the amount of the original parent isotope to the amount of the daughter isotopes that it breaks down into an age can be determined. You can learn more about fossils, dinosaurs, radiometric dating and related topics by reading through the links on the next page.
