Talk origins radioactive dating

Any erase will give bad centers when powered. See first point a above. Radioactlve phone original Engels cited by How clearly stated that dig presented from social of unwanted impurities in the most mineral being destroyed. Some examples and a red of a kind creationist american. In their lessons of errors, creationists do not just foundation of the globe. Kind Journal of Canada 19 3:.

Argon may be incorporated with potassium at time of formation. In the case of the claim about recent lava yielding dates that are millions to billions of years old, H. Morris misstated the facts concerning these "anomalous" dates as published in Funkhouser and Naughton The main misstatements of fact by Morris are as follows: It was not the lava that was dated, Talk origins radioactive dating inclusions of olivine, called "xenoliths", present within the lava. These gave anomalously old age because they contained excess argon that the enclosing lava did not. Morris failed to mention that the lava matrix without the xenoliths was dated and found to be too young to date using potassium-argon.

Funkhouser and Naughton [, ], stated that the matrix rock "can be said to contain no measurable radiogenic argon within experimental error. The presence of excess argon was only a problem for the xenoliths but not for the lava containing them. Morris cited other examples of anomalous dates produced by excess argon and falsely claimed that it is a universal problem for K-Ar dating. The problem is not universal, as the majority of minerals and rocks dated by K-Ar do not contain the excess argon. Morris's complaints are dated in that, for the most part, geologists no longer use the K-Ar dating technique as was practiced in This change also solved other problems that Morris complained about in his discussion of the K-Ar dating technique.

These complaints were as follows: K-Ar dating techniques must be calibrated by uranium-lead U-Pb dating. Some calibrations between U-Pb and K-Ar were done in the s and early s, but the decay rates of all the different radioisotopes involved are now known to within 1 percent, making the different dating techniques independent. This has been demonstrated by the dating of chondrite meteorites Dalrymple and tektites and other ejecta and deposits created by the giant meteorite impact at Chicxulub in the Yucatan Peninsula Dalrymple et al. The potassium-argon is an open system. The papers cited by Morris fail to probe this point.

The first paper simply demonstrates that rock altered by weathering cannot be dated. The final paper claims potassium is quite mobile because potassium can be extracted from iron meteorites by using distilled water. However, K-Ar dating commonly uses potassium silicate minerals, which are very insoluble in water and resist weathering. Potassium cannot be significantly leached from the minerals used in K-Ar dating, or, conversely, the minerals from which significant potassium can be leached are not the minerals used in K-Ar dating. The decay rate of potassium is subject to change.

Reprinted in Creation Research Society Quarterly 19 2: Any tool will give bad dqting when misused. Radiocarbon dating has some known limitations. Any measurement that exceeds these limitations will probably be invalid. In particular, radiocarbon dating works to find ages as old as 50, years but not much older. Using it to date older items will give bad results. Samples can be contaminated with younger or older carbon, again invalidating the results.

Because of excess 12C released into the atmosphere from the Industrial Revolution and excess 14C produced by atmospheric nuclear testing during the s, origina less than years old cannot be dated with radiocarbon Faure In their claims of errors, creationists do not consider misuse of the technique. It is not uncommon for them to misuse radiocarbon dating by attempting to date samples that are millions of years old for example, Triassic "wood" or that have been treated with organic substances. In such cases, the errors belong to the creationists, not the carbon dating method.
