A few principles were recognized and specified later.
An early summary of them is found in Charles Lyell's .
I've been reading a lot of stuff lately about people frustrated with dating.
It comes from both sides of the aisle: women who are frustrated that they simply can't find dateable men, and men who are frustrated that women are far too picky, and complaining there aren't any dateable men, when they seemingly just skip right over these all men who, on paper, meet all of those girls' supposed requirements. I researched dating and romantic history quite heavily for the relationship book I was writing last year (that I've since put on hold - I'm not in a position to effectively market another book just yet), and while a lot of male-female complaints are as old as time itself, I can tell you that this one - that there just aren't any dateable men, and that the women themselves are far too picky - is one I haven't encountered in the literature prior to the advent of the modern dating and relationship system in the early 20th century.
In no way are they meant to imply there are no exceptions.
There are situations where it potentially fails -- for example, in cave deposits.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.Geochronologists do not claim that radiometric dating is foolproof (no scientific method is), but it does work reliably for most samples.To get to that point, there is also a historical discussion and description of non-radiometric dating methods.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).My thanks to both him and other critics for motivating me.Much of the Earth's geology consists of successional layers of different rock types, piled one on top of another.If any portion of this agreement is deemed unenforceable by a court of competent jurisdiction it shall not affect the enforceability of the other portions of the agreement.his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale.It is these highly consistent and reliable samples, rather than the tricky ones, that have to be falsified for "young Earth" theories to have any scientific plausibility, not to mention the need to falsify huge amounts of evidence from other techniques.This document is partly based on a prior posting composed in reply to Ted Holden.
