A recent geological time scale, based on Harland et al. A critique of conventional geologic time scale should address the best and most consistent data available, and explain it with an alternative interpretation, because that is the data that actually matters to the current understanding of geologic time. If there are good reasons to expect problems with a sample, it is hardly surprising if there are! It's easy to assert that radiometric methods don't work, but it's quite another thing to prove it. Note that chronologically, fossil succession was well and independently established long before Darwin's evolutionary theory was proposed in When this happens, any later dating attempt will yield the age of that metamorphic event rather than the original time of crystallization: Geologists do sometimes find events that are "diachronous" i. If the isochron line has a distinctly non-zero slope, and a fairly large number of data points, the nearly inevitable result of contamination failure of the system to remain closed will be that the fit of the data to a line will be destroyed. If the age of this unit were not so crucial to important associated hominid fossils, it probably would not have been dated at all because of the potential problems. Next we shall examine in detail some specific examples. Calibrating the Relative Time Scale For almost the next years, geologists operated using relative dating methods, both using the basic principles of geology and fossil succession biostratigraphy. This is known as isotope fractionation.

    In the last or more years of their application, they are often valid, but geologists do not assume they are.
