I also cannot think of a single geological process that is inconsistent with an Earth that is many millions of years old. Hebert emphasized two examples of discordancy: Flaws in a Young-Earth Argument, Part 1 of 2.
To summarize, the YEC team used the present high rate of heat flow in this geothermal field and applied this to the entire thermal history of the area, rather than a thermal history model that takes into account the fact that these rocks have been much cooler for most of their history.
Warm mineral grains lose helium much more rapidly than cool grains do. This is another example of YECs using a distorted version of uniformitarianism by extending the present blindly into the past as the foundation for their young-Earth arguments. All of this biased the results in favor of a younger Earth. Hebert stated that radiocarbon dating assumes the same ratio of carbon radiocarbon in the atmosphere for thousands of years. I was really surprised that he said this; perhaps my notes are wrong. Hebert stated that there should be no carbon in samples over , years old. He then stated that carbon has been found in coal, dinosaur bones, diamonds, and petroleum, all of which are believed to be millions of years old.
It is true that any traces of original carbon in a sample should be gone after , years. But there are a number of perfectly reasonable ways for more recently-formed carbon to be present in ancient deposits. One is by groundwater contamination, which brings atmospheric carbon into underground systems. This would be particularly effective at bringing carbon into coal. But the most likely source for carbon in these samples is laboratory contamination.
Most of the carbon detected in YEC experiments has been at levels that push the limits of detection. It is impossible to completely clear mass spectrometers and other laboratory equipment of residues from previous analyses, and so chances are, virtually any sample analyzed will register at least some miniscule trace of carbon whether or not there was any actual carbon in the sample.
Hebert listed three conditions he called them assumptions that must be true in order for radiometric dating to work:. The first of these is true for some radiometric techniques, but not for all. In many cases, we know that there was some of the daughter isotope present in the sample when it formed. In both of these cases, the mathematics of the technique reveals the amount of daughter element that was present when the sample formed.
If you disagree, then your problem is with math, not with geology. The second condition must be fulfilled in order to determine an accurate radiometric date. Geochronologists will generally avoid samples that have obviously been altered since formation, as these are likely to have experienced gain or loss of either the parent or daughter nuclide.
Instead, they know that it is best to analyze samples that appear fresh, unaltered, and unweathered. For isochron techniques, the graphs produced by the analyses will usually reveal whether any parent or daughter elements have been added or removed. The third condition—constant decay rates—must also be true in order for radiometric dating to work. YECs have spent much effort trying to demonstrate that radioactive decay has greatly accelerated in the past, and have thus far been unsuccessful.
Other discordant dates, such as where K-Ar dates do not agree with Rb-Sr dates, are not uncommon in geological research, but they are also the exception in radiometric dating rather than the rule. For instance, when an igneous rock forms from magma, both the K-Ar and Rb-Sr clocks are set to zero. If the rock is re-heated but not melted millions of years later, such as by contact metamorphism, the Rb-Sr clock may keep on running, but argon may be driven out of the rock, resetting the K-Ar clock.
This will result in two discordant, but highly useful, dates: The scientist just has to be smarter than the rocks.
