When scientists at the University of Regina, Saskatchewan were asked what the results would be if these roots were dated by Potassium Argon method.Their response was that the results: Two well-documented examples of "heat contamination" are the 18 eruptions from two Hawaiian volcanoes.To do this they have selected a certain meteorite, which contained various types of lead (including lead 204, 206, 207 and 208) but no uranium, and they have assumed that this ratio is equivalent to the earth's original lead ratio.They did this because it is almost certain that these lead isotopes were all present in large quantities when the earth was created.The third assumption is that the sample has remained in a closed system.This is necessary due to outside influences such as heat and groundwater that can seriously alter the original material.And since the only rocks which yield ages in excess of 100,000 years are of volcanic origin, this method of dating the earth is not based on science, but rather speculation and subjective reasoning.
Leaching can also cause uranium to be leached into rocks that have little or no uranium in them.
Therefore, in virtually every case, scientists do not know what the original condition of the rock was; and, even if they did know, they don't any more due to heat contamination, mixing, and leaching. Snelling in an article on this topic Note: As for the few cases where scientists do know what the "original" condition (or date of eruption) was, they still have not been able to come up with the correct "date" for the age of the rock without all sorts of fancy footwork and massaging of data.
That's because radiometric dating (with the exception of Carbon 14) is almost always performed on igneous rocks (i.e. Also because, when different substances are in a liquid state, something known as mixing almost always takes place: meaning that whenever a liquid (or molten) rock is erupted out of the earth, both the mother and daughter elements will be "mixed" together, thus making it virtually impossible to determine the time that an eruption took place.
The following tables illustrate the highly questionable, if not totally unreliable, nature of the radiometric methods that are currently in use or have been used in the past to "date" volcanic materials. For the reasons discussed above, radiometric dating is not the absolute Time Clock that it has been portrayed to be by faithful evolutionists. 65,35) was not given, the ratios of Potassium -40 (K)/ Argon-40 (Ar) were listed in Table 1 on p. And though I agree with the writers of this article that this sample has an excess amount of Argon-40, I also think it is highly probable that the argon which contaminated this sample also contaminated all of the other samples, and that this breccia was simply "contaminated" with more Argon.
