Accurate dating methods

When a new fossil is discovered, geologists assign a date for when they think the plant or animal lived. They normally use radiometric dating methods to date the fossil, and many promote these methods as being accurate. Yet when you look into the technical papers on these discoveries, you find that these dates are often questionable and are sometimes clearly in error.

Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4. Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free. These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth's surface is moving and changing.

Here I want to concentrate on another source of error, namely, processes that take place within magma chambers. To me it has been a real eye opener to see all the processes that are taking place and their potential influence on radiometric dating. Radiometric dating is largely done on rock that has formed from solidified lava.

Interest in the origins of human populations and their migration routes has increased greatly in recent years. A critical aspect of tracing migration events is dating them. Inspired by the Geographic Population Structure model that can track mutations in DNA that are associated with geography, researchers have developed a new analytic method, the Time Population Structure TPSthat uses mutations to predict time in order to date the ancient DNA.

Radiometric dating is a much misunderstood phenomenon. Evolutionists often misunderstand the method, assuming it gives a definite age for tested samples. Creationists also often misunderstand it, claiming that the process is inaccurate.

It is an accurate way to date specific geologic events. This is an enormous branch of geochemistry called Geochronology. There are many radiometric clocks and when applied to appropriate materials, the dating can be very accurate.

Smith is known as the Father of English Geology. Source: Oxford Library. Our understanding of the shape and pattern of the history of life depends on the accuracy of fossils and dating methods.

Many people think that radiometric dating has proved the Earth is millions of years old. Even the way dates are reported e. However, although we can measure many things about a rock, we cannot directly measure its age.

The good dates are confirmed using at least two different methods, ideally involving multiple independent labs for each method to cross-check results. Sometimes only one method is possible, reducing the confidence researchers have in the results. Kidding aside, dating a find is crucial for understanding its significance and relation to other fossils or artifacts. Methods fall into one of two categories: relative or absolute.
