Dating the grand canyon bad speed dating stories


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.That data is lacking from Austin's published works.Besides, this line of argument does not address the fact that the result is a known and expected behavior of isochrons.One particular Precambrian layer known as the Cardenas Basalt has been dated by radiometric methods to about 1.1 billion years in age.The Cenozoic flows sampled by ICR thus are claimed to yield an age which is about 200 million years older than the Cardenas Basalt.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).

It also be the age of the flows, but it does not have to be.They believe that when different radio-dating methods are used on the same rocks, they will all yield the same age.But the quest to test this belief by sampling rocks from deep within Grand Canyon has found it is not true.Further, there is no material in Austin's book which legitimizes the false and misleading claims in his articles (which are free and available online) receive much wider distribution than Austin's book (which costs ).Many people, including many scientists, accept these dates as absolute truth.Even young-earth creationists would agree with this relative sequencing of events.
