Isotopic dating of the earth


In general, in one half-life, half of the parent will have decayed. If that happens to be billions of years, then the young-Earth is in big trouble. Modern counting instruments, available for more than two decades, are capable of counting the 14C activity in a sample as old as 35, years in an ordinary laboratory, and as old as 50, years in laboratories constructed with special shielding against cosmic radiation. The following was sent to me by a friend: Assuming we start out with pure parent, as time passes, more and more daughter will be produced. In between Russell's estimate and roughly World War II, a number of similar chemical ages for the Earth's crust were computed and published. By , increased confidence in radioisotope dating techniques and the demands of evolution theory for vast amounts of time led to the establishment of an expanded geological time scale. It is therefore essential to have as much information as possible about the material being dated and to check for possible signs of alteration. For dates up to a few million years micas , tektites glass fragments from volcanic eruptions , and meteorites are best used. In the ideal case, the geologist will discover a single rock unit with a unique collection of easily observed attributes called a marker horizon that can be found at widely spaced localities.
