Concordia
Isochron Dating
By Paul
Nethercott
May
2012
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
Evolutionists
give the age of the galaxy as “11 to 13 billion years for the age of the Milky
Way Galaxy.” 1,
7 Let us remember this as we look at the following dating
as given in secular science journals.
Age
and Mineralogy of Supergene Uranium
Theses
rocks from the Bohemian Massif, South East Germany 8 were dated in 2010 using
the Uranium-Lead dating method. The
table in the essay has three columns of isotopic ratios,
206Pb/238U, 207Pb/235U and
207Pb/206Pb. You will notice in Table 4 the original
article 9 that there are
dates besides the 206Pb/238U and
207Pb/235U ratios but no dates beside the
207Pb/206Pb ratios. The first two sets of ratios and dates
agree with each other between 94 and 101 percent accuracy. If we use the
computer program Isoplot 10
and calculate the ages of the 207Pb/206Pb ratios
we see why not dates have been put beside them. In Table 1 we can see that many
dates are negative. That is logically impossible. How can the rock have formed
millions of years in the future?

In Table 2 we can see that the
207Pb/206Pb dates are between 1,000 to 21,000
percent discordant when compared to the two Uranium-Lead dating methods. Here is
just one of many times where geology journals use selective evidence to try and
prove evolution. If the third column or ratios were dated and added to the essay
you can see how silly it would look.

207Pb–206Pb and
40Ar–39Ar ages from SW Montana
These rocks from
North America were dated in 2002 using both 11 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 12 using the
40Ar–39Ar
dating method. The third table 13 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
Potassium-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?

Diagram
1
According to the
Iscohron [1, 2 and 3] diagrams in the article 16 the meteorites are only supposed to be 200
million years old! This means that the dates are 4,800 million years in error.
The ratio of the so called “true” age versus the 207Pb/206Pb age is 25 to 1. The
author deliberately chose not to put the dates beside the isotopic ratios
because they would show how utterly ridiculous the whole system is.
According to the Iscohron diagram in the article, the maximum error level
is only 83 million years. The error level is 4934 years if we compare it to
the 207Pb/206Pb age.
This means the error level is 59 times in error.
Pb–Pb Dating Of
Chondrules
The meteorite
samples 17 were dates in 2009 by scientists form the Geological Museum, University of Copenhagen and The
University of Texas at Austin. If we use Isoplot and run some of the
207Pb/206Pb ratios given in the article 18
through Microsoft Excel we see that many of
the ratios produce ages over 5 billion years old.
Below we can see
a Concordia diagram taken from the article 19 that shows the age of
the rocks to be 4,565 million years old. As you can see the diagram claims that
the error margins is only 810,000 years! If
we add the 207Pb/206Pb
ratios dates we can see that the diagram is out by 550 million years. That means
the error margin given in the diagram is 677 times to
short!

Pb–Pb Dating

This
dating 20 was done in 2007 on meteorite samples by the Washington State
University, Department of Geology. We can see from table seven which data in my
essay the data was obtained from in Audrey Bouvier’s

Chondrules:

Pyroxenes: 4564.3 ± 0.8
Ma
Phosphates:
4562.7 ± 0.7 Ma
We are told that
the date of 4,565 million years old is only one million years in error at the
maximum. If run some of the
207Pb/206Pb ratios given in the article through Isoplot,
we see that many of the ratios produce ages over 5 billion years old. The oldest
is 5,379 million years. The error margin given in the article is 814 times in
error.

U–Th–Pb
Dating of Hydrothermal ore Deposits
This
dating 22 was done in
2010 on rocks from eastern China. If we look at one of the tables 23 in the original essay we
see four columns of isotopic data 207Pb/206Pb,
207Pb/235U, 206Pb/238U and
208Pb/232Th. Three have dates beside them but here are no
dates beside the 207Pb/206Pb ratios. If we run the
207Pb/206Pb ratios through Isoplot we soon see why there
are no dates beside them. According to the Concordia diagrams in the essay
24 the rocks are supposed to be 137 million years old with an average
age of 120 million years.

Some
of the dates listed in the article 23 are older than the age of
the Solar System and Galaxy! The author offers an explanation: “Due to the very
low Th contents in the calcite-hosted titanite, no meaningful 208Pb/232Th ages
were obtained.” 25
U–Th–Pb Dating
of Yucca Mountain, Nevada
This dating was
done 26 in 2008 by the
U.S. Geological Survey office in Denver, Colorado. You will notice in Table 1 the original article 27 that there are no dates
beside 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 dates are
between 5,450 and 8,186 million years old. The average age is 6,320 million
years old. Table 3 in the original article 28 has dates older than
the universe and extreme discordance with up to 2 million percent. The average
discordance is 212,000 perecent!
40Ar/39Ar
and U-Th-Pb Dating
This
meteorite sample 29 was
dated in 1983 by Donald Bogard from the Johnson Space Center, Houston Texas. If
we look in Table 5 in the original article we see that there are dates beside
the 207Pb/208Pb
ratios no dates beside the 207Pb/206Pb
ratios. If
we run the 207Pb/206Pb
ratios through Isoplot we see that they uniformly differ with the
207Pb/208Pb dates given in the essay. The author’s choice
to drop these dates and only have dates beside the
207Pb/208Pb ratios is just an arbitrary
choice.

Isotopic Lead
Investigations
These meteorite
samples were dated in 1975 by the Department of Geological Sciences, University
of California, Santa Barbara, California. 31 From Table 2 in the
original article we can calculate the 207Pb/206Pb ratios and then we run
them through Isoplot. The ages are
consistently older than the age of the Solar System.

Extraordinary Examples
Below are dates
calculated from Pb207/206 isotopic ratios listed in standard geology magazines.
The majority of ratios give dates of 5 billion years old. The model age put
forward is radically different.

Conclusion
Prominent
evolutionist Brent Dalrymple states: “Several events in the formation of the
Solar System can be dated with considerable precision.” 33
Looking at some
of the dating it is obvious that precision is much lacking. He then goes on:
“Biblical chronologies are historically important, but their credibility began
to erode in the eighteenth and nineteenth centuries when it became apparent to
some that it would be more profitable to seek a realistic age for the Earth
through observation of nature than through a literal interpretation of
parables.” 34
The Bible
believer who accepts the creation account literally has no problem with such
unreliable dating methods. Much of the data in Dalrymple’s book is selectively
taken to suit and ignores data to the contrary.
