Radioctive dating against evolution

Addresses and refutes the common defensive statements used by proponents of the dating methods.

Special emphasis is on demonstrating that discrepant results are not the exception, but the rule, and that arguments used to justify so-called good dates are, when closely examined, arbitrary and without foundation. But the reality of the day is that any method based on assumptions can never offer absolute results.

By dating these surrounding layers, they can figure out the youngest and oldest that the fossil might be; this is known as "bracketing" the age of the sedimentary layer in which the fossils occur.

It is clear that the sedimentary rock was deposited and folded before the dyke was squeezed into place.

By looking at other outcrops in the area, our geologist is able to draw a geological map which records how the rocks are related to each other in the field.

Nearly 50 years after Darwin published , research on radioactive elements in rocks provided the first reliable evidence that the earth was old enough to accommodate the evolution of complex organisms.

Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geological time scale.

Among the best-known techniques are radiocarbon dating, potassium-argon dating and uranium-lead dating.

Their method, a type of radiometric dating called uranium-lead (U-Pb) dating, relies on the fact that uranium isotopes radioactively decay to form lead isotopes.

By comparing the amount of each isotope in a sample, the age of the sample can be calculated.
