Potassium dating accuracy

Rated 4.47/5 based on 793 customer reviews

Different methods have their own limitations, especially with regard to the age range they can measure and the substances they can date.

A common problem with any dating method is that a sample may be contaminated with older or younger material and give a false age.

How do they know the decay rate has been the same for millions or billions of years? A portion of this sample was crushed, sieved, and processed into a whole rock powder as well as four mineral concentrates. " Design Science Association, retrieved Dec 19, 2012, [ See also Hans-Joachim Zillmer, Volcanic (igneous) rock, according to evolutionists, is the best way to date ages with K-Ar dating because, theoretically, when a volcano erupts, all the argon gas is released from the rock, and resets the clock back to zero.

To put it bluntly, the evolutionists have no clue, but "In June of 1992, Dr. -Keith Swenson, author who went on the expedition to gather igneous rock with Dr. This all sounds good in theory, but in practice, like with the rock in Mount St.

This process is used by evolutionists to claim dates to the earth going back 4.6 billion years. Bring decay rates into a court of law to be put under real scrutiny, and a good case could be made against them, but I don't think that's necessary to show the major problems evolutionists already have with what they are claiming, so in this instance, I won't be arguing what they claim as a current decay rate for K-Ar.

Evolutionists today see a half-life decay rate of potassium to argon at 1.3 billion years.

Familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.

One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.

People wonder how millions of years could be squeezed into the biblical account of history. Christians, by definition, take the statements of Jesus Christ seriously.

Sedimentary rocks are rarely useful for dating because they are made up of bits of older rocks.

Uranium is present in many different rocks and minerals, usually in the form of uranium-238.

Since there doesn't seem to be any systematic error that could cause so many methods to agree with each other so often, it seems that there is no other rational conclusion than to accept these dates as accurate.

However, this causes a problem for those who believe based on the Bible that life has only existed on the earth for a few thousand years, since fossils are found in rocks that are dated to be over 500 million years old by radiometric methods, and some fossils are found in rocks that are dated to be billions of years old.
