What does radiometric dating tell us. Radiometric dating | the institute for creation research
Thus later lava flows give younger K-Ar ages. Regardless of what method we use, we must start with assumptions and interpret the facts accordingly.
Modern lava flows often come down the sides of volcanoes, and thus become separated from their source by large distances. However, dating of bones can be more problematic, as bones are more susceptible to contamination by the surrounding soils. It is not clear to me, also, how often such a test for initial argon 40 is performed.
For each geologic period and each dating method, we will get a distribution of values. Here is another quote from Woodmorappe about isochrons, since some people think that mixing scenarios or other age-altering scenarios are unlikely: He simply gives the correct value for the K-Ar system.

The overall result is that no one has found any evidence of changes in fundamental constants, to an accuracy of about one part in per year. Thus we can get an apparent correlation of different methods without much of a real correlation in nature.
Helium escapes from the crystals at a known, measurable rate. The construction of this time scale was based on about radioisotope ages that were selected because of their agreement with the presumed fossil and geological sequences found in the rocks.
Samples with flat plateaus which should mean no added argon can give wrong dates. Thus, a large amount of Ar40 was present in the beginning. Thus radiometric dating methods appear to give evidence that the earth and meteorites are old, if one accepts the fact that decay rates have been constant.
Potassium 40 K40 decays to argon 40, which is an inert gas, and to calcium.

So the loss of a tiny amount of argon can have significant effects over long time periods. These will be discussed in the next section.
I suppose earthquakes could also allow the release of argon from the magma. Evolutionists assume the layers, called varves, roughly correspond to years based on assumptions about present processes. Do all scientists accept the carbon dating method as reliable and accurate? It is interesting that Woodmorappe gives a number of cases in which standard geological tests are ignored.
Here are a couple of more Boy dating girl games about anomalies: The rapid cooling might mean that any enclosed argon is retained, but if not, the fact that this cooling occurs near the volcano, with a lot of argon coming out, should guarantee that these beads would have excess argon.
Creation scientists suggest that there are two possible times that God supernaturally intervened on a global scale—during Creation Week and the Flood. Varves are also used to date other lakes around the world to the time of the last ice age—supposedly 10, years ago. Because it would take an extremely elaborate scheme to make up his existence, including forgeries, fake photos, and many other things, and besides, there is no good reason to simply have made him up.
