Relative rock dating methods

Geologists can employ two basic methods to dating rocks and fossils.Relative and absolute geologic dating practices have their strengths and weaknesses, which are inherent to their process.The example used here contrasts sharply with the way conventional scientific dating methods are characterized by some critics (for example, refer to discussion in "Common Creationist Criticisms of Mainstream Dating Methods" in the Age of the Earth FAQ and Isochron Dating FAQ).A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging.The primary issue is the lack of "real" dates, as in assigning a numerical value to the number of years that have passed since the formation of the rock sample.

To avoid this simple pitfall, a geologist must be sure to take mineral and rock samples from freshly broken pieces, rather than exposed or weathered surfaces.These are often characterised as the norm, rather than the exception.I thought it would be useful to present an example where the geology is simple, and unsurprisingly, the method does work well, to show the quality of data that would have to be invalidated before a major revision of the geologic time scale could be accepted by conventional scientists.Although this article highlights a brief overview of two basic types of geologic dating, it is not meant to represent all methods of dating, and it is also not meant to be a comprehensive review of relative and absolute methods.Rather, this is a simplified explanation paired with their apparent weaknesses.

his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale.
