-argon and argon-argon dating of crustal rocks and the problem of excess argon. not only that, they have to show the flaws in those dating studies that provide independent corroborative evidence that radiometric methods work. 40ar/39ar dating into the historical realm: calibration against pliny the younger. in order to accomplish their goal of discrediting radiometric dating, however, creationists are faced with the daunting task of showing that a preponderance of radiometric ages are wrong — that the methods are untrustworthy most of the time. no — it is the result of extremely careful analyses using a technique that works.

ngauruhoe, new zealand,And the implications for potassium-argon ‘dating,’” in proceedings of the fourth. few verified examples of incorrect radiometric ages are simply insufficient to prove that radiometric dating is invalid. results of the manson impact/pierre shale dating study (izett and others 1998) are shown in figure 1. numerous thin beds of volcanic ash occur within these coals just centimeters above the k-t boundary, and some of these ash beds contain minerals that can be dated radiometrically. scientists who use radiometric dating typically use every means at their disposal to check, recheck, and verify their results, and the more important the results the more they are apt to be checked and rechecked by others.

many people, radiometric dating might be the one scientific technique that most blatantly seems to challenge the bible’s record of recent creation."excess argon": the "archilles' heel" of potassium-argon and argon-argon "dating" of volcanic rocks. second, the radiometric age measurements, 187 of them, were made on 3 different minerals and on glass by 3 distinctly different dating methods (k-ar and 40ar/39ar are technical variations that use the same parent-daughter decay scheme), each involving different elements with different half-lives. in 1997 a team of scientists from the berkeley geochronology center and the university of naples decided to see if the40ar/39ar method of radiometric dating could accurately measure the age of this very young (by geological standards) volcanic material. other creationists have focused on instances in which radiometric dating seems to yield incorrect results.

its exact location in the stratigraphic column at any locality has nothing to do with radiometric dating — it is located by careful study of the fossils and the rocks that contain them, and nothing more. some so-called creation scientists have attempted to show that radiometric dating does not work on theoretical grounds (for example, arndts and overn 1981; gill 1996) but such attempts invariably have fatal flaws (see dalrymple 1984; york and dalrymple 2000).'t radioisotope dating prove rocks are millions of years old? is not the only dating study to be done on an historic lava flow. tektites are easily recognizable and form in no other way, so the discovery of a sedimentary bed (the beloc formation) in haiti that contained tektites and that, from fossil evidence, coincided with the k-t boundary provided an obvious candidate for dating.
