Unreliability of Radiometric Dating and Old Age of the Earth

Reference to a case where the given method did not work This is perhaps the most common objection of all. Creationists point to instances where a given method produced a result that is clearly wrong, and then argue that therefore all such dates may be ignored. Such an argument fails on two counts: First, an instance where a method fails to work does not imply that it does not ever work. The question is not whether there are “undatable” objects, but rather whether or not all objects cannot be dated by a given method. The fact that one wristwatch has failed to keep time properly cannot be used as a justification for discarding all watches.

The Age of the Earth

Outlook Other Abstract The Somerset Dam layered mafic intrusion in southeast Queensland, Australia, has been conventionally dated as Late Triassic by the apparently successful application of radioisotopic dating techniques. It is concluded that the Somerset Dam layered mafic intrusion has inherited the radioisotopic signature of its mantle source, and so the conventional radioisotopic dating techniques do not provide its true age. The outcrop is somewhat oval shaped, covering an area of about 4 km2 with a diameter of about 1.

It is a small layered gabbro intrusion with an exposed stratigraphic thickness of m on a steep hillside. It is a well-preserved, well-exposed, steep-sided, discordant intrusion which is undeformed and unmetamorphosed.

Blind Leading the Blind: Because radiometric dating utterly refutes their biblical interpretations, young-Earth creationists YECs are desperate to undermine the reliability of these dating methods. As part of their efforts, YECs clearly believe that they can discredit K-Ar dating if they can show that excess argon routinely enters rocks and minerals as they form.

That is, they believe that excess argon will cause rocks and minerals that are supposedly less than 10, years old to have ‘deceptively’ old K-Ar dates of millions or billions of years. In particular, YECs attempt to demonstrate that excess argon is a ‘problem’ for K-Ar dating by locating examples of historically erupted volcanics, which yield K-Ar dates that are hundreds of thousands or millions of years older than their eruption dates. The data were miscopied from Dalrymple Brent Dalrymple is a geochronologist with 40 years experience, a pioneer in the identification of excess argon in igneous samples, and an outspoken critic of young-Earth creationism e.

The Evolution of Early Man

Whenever the worldview of evolution is questioned, this topic always comes up. Let me first explain how carbon dating works and then show you the assumptions it is based on. Radiation from the sun strikes the atmosphere of the earth all day long. This energy converts about 21 pounds of nitrogen into radioactive carbon

The generally accepted age for the Earth and the rest of the solar system is about billion years (plus or minus about 1%). This value is derived from several.

Advanced Search Abstract Under particular climatic conditions, tetravalent K-Mn oxides can be formed during terrestrial chemical weathering of Mn ores. Some samples of dated cryptomelane had finely banded textures, and therefore might represent several generations. Total fusion age determinations of several groups of growth bands of a late Oligocene densely layered cryptomelane from the Woodie Woodie Mn deposit NW Australia suggest an averaged growth rate of 0.

Pro Radiometric dating is the method for establishing the age of objects by measuring the levels of radioisotopes in the sample. One example is carbon dating. Carbon 14 is created by cosmic rays in the upper atmosphere. It decays to nitrogen 14 with a half life of years. C14 is continually being created and decaying, leading to an equilibrium state in the atmosphere. When the carbon dioxide, containing C14 as well as stable C12 and C13, is taken in by plants it is no longer exposed to the intense cosmic ray bombardment in the upper atmosphere, so the carbon 14 isotope decays without being replenished.

Measuring the ratio of C14 to C12 and C13 therefore dates the organic matter for periods back to about eight half-lives of the isotope, 45, years. After a long enough time the minority isotope is in an amount too small to be measured. There are about two dozen decay pairs used for dating. Uranium decay to lead has a half-life of million years, so it is well suited to dating the universe.

Some radiometric dating methods depend upon knowing the initial amount of the isotope subject to decay.

The Age of the Earth

Even slight ranges of error in determining the “temperature history” of a specimen will result in huge “age” calculation errors. Calibrating for even a known temperature history also seems to be rather problematic. Consider that the rate of racemization for various amino acids is determined by placing a protein into a very high temperature environment between 95o and o C and then extrapolating these results to low temperature environments.

We argue that the D:

At the time that Darwin’s On the Origin of Species was published, the earth was “scientifically” determined to be million years old. By , it was found to be 1. In , science firmly established that the earth was 3. Finally in , it was discovered that the earth is “really” 4. In these early studies the order of sedimentary rocks and structures were used to date geologic time periods and events in a relative way.

At first, the use of “key” diagnostic fossils was used to compare different areas of the geologic column. Although there were attempts to make relative age estimates, no direct dating method was available until the twentieth century. However, before this time some very popular indirect methods were available. For example, Lord Kelvin had estimated the ages of both the Earth and the Sun based on cooling rates.

The answer of 25 million years deduced by Kelvin was not received favorably by geologists.

How old is that rock? In this blog I am going to talk about a specific dating technique called potassium-argon K-Ar dating. In terms of dating, one of the simplest geological events is a volcanic eruption, because these happen instantaneously on geological timescales. Volcanoes exist because of pockets of magma molten rock stored in the crust. As magma cools or changes pressure it starts to grow crystals. Some of these crystals contain K.

The Radiometric Dating Game Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years. We are told that these methods are accurate to a few percent, and that there are many different methods. We are told that of all the radiometric dates that are measured, only a few percent are anomalous.

This gives us the impression that all but a small percentage of the dates computed by radiometric methods agree with the assumed ages of the rocks in which they are found, and that all of these various methods almost always give ages that agree with each other to within a few percentage points. 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 million years old by radiometric methods, and some fossils are found in rocks that are dated to be billions of years old.
