503–525 (1998), and is reproduced here with the permission of the Creation Science Fellowship of Pittsburgh ( Ngauruhoe is an andesite stratovolcano of 2291 m elevation, rising above the Tongariro volcanic massif within the Tongariro Volcanic Center of the Taupo Volcanic Zone, North Island, New Zealand (fig.

Etna basalts (a 'date' of 150,000 years for a sample that erupted in 1792 AD and a K-Ar 'date' of 100,000 years for the other sample, which erupted in 122 BC), a plagioclase from Mt. Ngauruhoe in the Taupo Volcanic Zone, produced andesite flows in 19 and avalanche deposits in 1975.Potassium-argon “dating” of five of these flows and deposits yielded K-Ar model “ages” from Ar* content.Potassium decays into argon gas with a half-life of 1.251 billion years (we will round it up to 1.3 to keep things simple).That means, in 1.3 billion years, half of a potassium sample with decay to argon gas.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.

Then, in ANOTHER 1.3 billion years (2.6 total), the remaining half will decay.

Then, in ANOTHER 1.3 billion years (3.9 total), the remaining 1/4 will decay, and so on.

"If ye fulfil the royal law according to the scripture, Thou shalt love thy neighbour as thyself, ye do well: But if ye have respect to persons, ye commit sin, and are convinced of the law as transgressors." James 2:8 In "The Carbon Dating Game," we covered flaws, assumptions, and cherry-picking in dating methods that are said to be used for up to 50,000 years, which many evolutionists still use to say the dates of the Bible incorrect.

In this article, we will be going over potassium-argon dating (K-Ar) to explain the flaws, assumptions, and cherry-picking in dating methods that are said to be used in dating billions of years, and according to most evolutionists, "proof" of an old-earth.

Symbolically, the process of radioactive decay can be expressed by the following differential equation, where N is the quantity of decaying nuclei and k is a positive number called the exponential decay constant.
