Is radiometric dating flaws in the bible, search form

History of the Radioisotope based Geologic Time Scale Before the discovery of radioactivity in the late nineteenth century, a geological time scale had been developed on the basis of estimates for the rates of geological processes such as erosion and sedimentation, with the assumption that these rates had always been essentially uniform.

They would all have excess argon due to this movement.

Radiometric dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life.

The time machine is called the telescope. So to assume that the K-Ar dates, Rb-Sr dates, and U-Pb dates all reflect the age of the lava, one would have to assume that this lava had no Sr, no Pb, and that all the argon escaped when the beads formed. It is also being claimed that the standard deviations are not too large.

A ratio of zero means an age of zero. Billions of years are needed to make the evolution theory look good.

It only differs in degree.

The second thing is that some of the results have been repeated using the same technique, which is another check against analytical errors. Creationists who wants to dispute the conclusion that primitive meteorites, and therefore the solar amici di letto streaming megavideo yahoo dating, are about 4.

The fact that they soon are covered over means that the argon has a hard time escaping vertically from the lava, so argon coming up from the mantle will tend to enter the cooling rock. So one sees that there is a tremendous potential for age increases in this way.

The relationship between the data obtained and a specific event must be known. Furthermore, the question arises whether bentonite always gives correlated ages, and whether these ages always agree with the accepted ages for their geologic period.

This also could make flows on the land appear older than they are, since their Ar40 would also have a harder time escaping. Because of this, the uranium, and its contribution to the thorium abundance, can in many cases be ignored in sediments. This has been done for the "Methuselah of trees", the bristlecone pine trees, which grow very slowly and live up to 6, years.

If more excess argon were present, then we could get much older ages. And how do we know that it could not be a much larger quantity in other cases? What I can offer is my own experience as it relates to the accuracy of the Bible.

The cosmic-ray exposure ages of meteorites are usually around 10 million years, but can be up to a billion years for some iron meteorites.

Carbon Dating Flaws – Doesn’t Carbon Dating Disprove the Bible?

Is this just a coincidence? But argon does not need to move through all rock in order to influence radiometric dates, it only has to reach ancient lava flows. If you look at a periodic table you will notice that Carbon and Nitrogen are right next to each other.

Some are from primitive asteroids whose material is little modified since they formed from the early solar nebula. Many more, plus a discussion of the different types of meteorites and their origins, can be found in Dalrymple It is impossible to know how much carbon 14 was in it at death and it is impossible to know if carbon 14 has always decayed at the same rate.

For example, different kinds of quartz have different colors due to various impurities that are included but not part of the repetitive unit of the quartz crystal. Again it is obvious that they are not millions of years old.

The argon that may either diffuse into the minerals or may be occluded within them is derived by outgassing of K-bearing minerals in the crust and mantle of the Earth. Thus the temperature does not have to be very high for argon to move through rock. The rapid cooling might mean that any enclosed argon is retained, but if not, the fact that this cooling occurs near the volcano, with a lot of argon coming out, should guarantee that these beads would have excess argon.

First, we must assume that the rate of decay of U into Pb has remained constant over time.

This type of lava cools quickly, leaving little time for crystals to form, and forms basalt. In general, older rocks should have more argon because they have been subject to more exposure to such argon, but their true age is not necessarily related to their K-Ar radiometric age.

But since these multiple mixing tests are more difficult and expensive, they may not be done very often.

And yet the results are the same within analytical error. Neither date would necessarily be seen as anomalous. The K-T tektites were ejected into the atmosphere and deposited some distance away. Since Cambrian and later rocks are largely sedimentary and igneous volcanic rocks are found in Cambrian and later strata, if these rocks are really million years old, then life must also be at least million years old.

There is far too much Ar40 in the earth for more than a small fraction of it to have been formed by radioactive decay of K In addition, Woodmorappe gives over sets of dates "that are in gross conflict with one another and with expected values for their indicated paleontological positions.

For example, dates may be accepted even when there is evidence of weathering, and rejected when there is not. They made two bad assumptions after they came up with this calculation. It is not necessary for this increase in age to happen all at once; many events of this nature can gradually increase the K-Ar ages of rocks.

But it is more difficult to remove argon that has deposited on cracks in the mineral, which can be difficult to see. First, it provides no evidence whatsoever to support their claim that the earth is very young.

If these dates are correct, this calls the Biblical account of a recent creation of life into question. The answer is that these methods, are far from infallible and are based on three arbitrary assumptions a constant rate of decay, an isolated system in which no parent or daughter element can be added or lost, and a known amount of the daughter element present initially.

So the loss of a tiny amount of argon can have significant effects over long time periods. Cross-examination The Mobility of Argon Dr. It is derived from a transcript of Dr. Read Matthew chapter 14 and Like chapter 21 to see the change in conditions predicted for the time we live in and 2 Timothy Chapter 3 for the predictions of the increasing bad attitudes of PEOPLE in this time.

Samples giving no evidence of being disturbed can give wrong dates. Scientists have concluded that it is not; it is instead a consequence of the fact that radiometric dating actually works and works quite well.

Henke states that hornblendes retain argon very well, but then later says that they can easily absorb excess argon. During the ice age, long-lived trees grew in different areas than they do now.

The fatal flaw with radioactive dating methods – Biblical Geology

This will cause them to retain argon and appear too old. My answer is that it is similar to believing in other things of the past. A small amount of data beyond 40, years not shown in Fig.
