Rb sr method of dating

An angular unconformity is the result of tilting and eroding of the lower layers before the upper ones are deposited.These tilted and eroded layers are Precambrian in age (blue in Figure 1, above).In this article I shall point out some other dating methods which work the same way as the Rb-Sr method.The reader who has not read the article on the Rb-Sr method will find this present article almost completely incomprehensible, and should go back and read it.The attempt to abuse the meaning of a single contrived date -- which was produced only by a sample selection geared to dating a different event, and only for samples whose results were known by Austin in advance -- says a lot more about the level of competence or honesty in this creation "science" research program, than it says about the validity of isochron dating methods.Even if given credit for discovering this case (which he clearly doesn't deserve, as his use of Leeman's data proves), Austin has only managed to "call into question" a particular sampling technique.The ICR's Grand Canyon Dating Project does not strike a telling blow against the reliability of isochron dating.

Furthermore, the half-life is far too long for any practical hydrologic application.But the Cardenas Basalt cannot be younger than the plateau flows, due to the geological relationships discussed in the first section of this document.Austin says that his isochron age is the result of a "" (1992, p. In other words, Austin claims that he has produced a seemingly reliable isochron age which must necessarily be wrong, and therefore the Rb-Sr isochron dating method, which is considered to be among the more reliable of radiometric dating methods, must be considered suspect.The canyon must be younger than the rock layers that it cuts into.The sediments above the angular unconformity must be younger than the sediments below it.
