    Importance of potassium argon dating

    Relative dating methods do not tell archaeologists exactly how old things are, but only how old things are relative to each other.

    Archaeologists work on the principle that objects at the bottom of an undisturbed were put there before objects that are above them, so objects found in the lower levels of a site are usually older than objects found in higher levels.

    Third, evolution of living organisms into more advanced life forms by natural selection or mutations.

    This work explains these erroneous ages by « excess » argon (radiogenic and/or primeval) in volcanic rocks under study.

    This excess argon greatly alters the calculated age and puts into question the validity of the method.

    Anomalous « K/Ar model ages » are frequently reported in the literature.

    These assumptions are not demonstrated, only supposed to be true.

    To give an example of the complexity of this problem, this paper presents a study of the most popular dating method, potassium/argon.

    The belief that radiodating methods give absolute measurements of time is widespread as a result of scientific popularization in journals, conferences, and the media.

    In fact, due to the difficulties in applying the experimental method to events in the past, all chronometers based on natural or artificial nuclear disintegration need a calibration.
