The 40Argon/39Argon Dating Method

By Paul Nethercott

April 2014

 

How reliable is radiometric dating? We are repeatedly told that it proves the Earth to be billions of years old. If radiometric dating is reliable than it should not contradict the evolutionary model. According to the Big Bang theory the age of the Universe is 10 to 15 billion years.1 Standard evolutionist publications give the age of the universe as 13.75 Billion years. 2, 3

Standard evolutionist geology views the Earth as being 4.5 billion years old. Here are some quotes from popular text: “The age of the Earth is 4.54 ± 0.05 billion years.” 4 The Solar System, formed between 4.53 and 4.58 billion years ago.” 1 “The age of 4.54 billion years found for the Solar System and Earth.” 1 “A valid age for the Earth of 4.55 billion years.” 5, 6

                If we run the isotopic ratios give in standard geology magazines through the computer program Isoplot 7 we find that the Uranium/Thorium/Lead isotopic ratios in the rocks disagree radically other dating methods. The U/Th/Pb ratios give ages older than the evolutionist age of the Earth, Solar System, Galaxy and Universe. How can Earth rocks be dated as being older than the Big Bang? Here are examples of isotopic ratios taken from several articles in major geology magazines which give absolutely absurd dates.

 

 

207Pb/206Pb and 40Argon/39Argon ages from South West Montana

These rocks from North America were dated in 2002 using both 8 40Argon/39Argon and Lead-Lead dating methods. Again the no dates beside the 207Pb/206Pb ratios. If we add dates we soon see why. The first table in his article has dates 9 using the 40Ar–39Ar dating method. The third table 10 has the 207Pb/206Pb ratios.

If we use the computer program Isoplot and calculate the ages of the 207Pb/206Pb ratios we see why not dates have been put beside them. The Argon-Argon and Lead-Lead dating methods are extremely discordant. The author’s use of data is very selective. Dates that agree are added and those that do not are omitted. This happens over and over in geology magazines. We can see from the table below that many dates are older than the evolutionist view of the age of Earth. How can such an absurdity be possible? How can the Earth be older than itself?

Shocked Meteorites: Argon-40/Argon-39

Dated in 1997 by scientists 11 from Germany and France, these meteorite samples gave astounding results also. Many dates were older than the evolutionist age of the Solar System, older than the evolutionist age of the galaxy and older than the Big Bang. 12 Most age results that were hundreds or thousands of percent discordant.

U-Th-Pb Dating of Abee E4 Meteorite

This dating was done in 1982 by scientists from the NASA, Johnson Space Center, Houston Texas and the U.S. Geological Survey, Denver, Colorado.15 The two table below [Table 5, 6] are a summary of Argon dating done on different meteorite samples.16 Both sample record dates older than the evolutionist age of the solar system. The original article has undated 207Pb/206Pb ratios. If we run the through Isoplot 7 we find the ratios 17, 18 give the results in tables 7 and 8. All are much older than the evolutionist age of the solar system.

Ar-39/Ar-40 Dating of IAB Iron Meteorites

In 1979 this dating was carried out by the Department of Physics, University of California, Berkeley. 23 One of the meteorites was dated at almost ten billion years old. 24 I will use the following Argon/Argon dating formula 25 listed in Brent Dalrymple’s book:

 

 

Where T is the age in years and J is the special constant. If we run a list of eighty Argon 40/39 ratios listed 26 in Niemeyer’s article through Microsoft Excel we get eighty dates. The J value 24 is listed in the article as 0.03754.  Twenty six dates [32%] are over 4.6 billion years old. Twenty one dates [26%] are over 5 billion years old. Thirteen dates [16%] are impossible future ages. The dates vary from negative 2.42 billion to positive 9.59 billion years old. There is a 12 billion year range of dates. In the table below we can see the comparison between the so called “Model Age” 24 and dates calculated from the eighty ratios 26.
